CVE-2026-40068 (GCVE-0-2026-40068)

Vulnerability from nvd – Published: 2026-05-05 20:52 – Updated: 2026-05-06 15:24

Title

Claude Code arbitrary code execution via git worktree commondir trust dialog bypass

Summary

In versions 2.1.63 through 2.1.83 of Claude Code, the folder trust determination logic used the git worktree commondir file without validating its contents. An attacker could craft a malicious repository with a commondir file pointing to a path the victim had previously trusted, causing Claude Code to bypass its trust confirmation dialog and immediately execute hooks defined in `.claude/settings.json`. Exploitation requires the victim to clone the malicious repository and run Claude Code within it, and the attacker must know or guess a path the victim had already trusted. This issue has been fixed in version 2.1.84.

Severity

7.7 (High)

CVE-2026-39861 (GCVE-0-2026-39861)

Vulnerability from nvd – Published: 2026-04-21 00:56 – Updated: 2026-04-21 13:44

Title

Claude Code: Sandbox Escape via Symlink Following Allows Arbitrary File Write Outside Workspace

Summary

Claude Code is an agentic coding tool. Prior to version 2.1.64, Claude Code's sandbox did not prevent sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code subsequently wrote to a path within such a symlink, its unsandboxed process followed the symlink and wrote to the target location outside the workspace without prompting the user for confirmation. This allowed a sandbox escape where neither the sandboxed command nor the unsandboxed app could independently write outside the workspace, but their combination could write to arbitrary locations, potentially leading to code execution outside the sandbox. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window to trigger sandboxed code execution via prompt injection. Users on standard Claude Code auto-update have received this fix automatically. Users performing manual updates are advised to update to version 2.1.64 or later.

CVE-2026-35603 (GCVE-0-2026-35603)

Vulnerability from nvd – Published: 2026-04-17 20:38 – Updated: 2026-04-20 14:57

Title

Claude Code: Insecure System-Wide Configuration Loading Enables Local Privilege Escalation on Windows

Summary

Claude Code is an agentic coding tool. In versions prior to 2.1.75 on Windows, Claude Code loaded the system-wide default configuration from C:\ProgramData\ClaudeCode\managed-settings.json without validating directory ownership or access permissions. Because the ProgramData directory is writable by non-administrative users by default and the ClaudeCode subdirectory was not pre-created or access-restricted, a low-privileged local user could create this directory and place a malicious configuration file that would be automatically loaded for any user launching Claude Code on the same machine. Exploiting this would have required a shared multi-user Windows system and a victim user to launch Claude Code after the malicious configuration was placed. This issue has been fixed on version 2.1.75.

Severity

CVE-2026-33068 (GCVE-0-2026-33068)

Vulnerability from nvd – Published: 2026-03-20 08:17 – Updated: 2026-03-20 13:48

Title

Claude Code has a Workspace Trust Dialog Bypass via Repo-Controlled Settings File

Summary

Claude Code is an agentic coding tool. Versions prior to 2.1.53 resolved the permission mode from settings files, including the repo-controlled .claude/settings.json, before determining whether to display the workspace trust confirmation dialog. A malicious repository could set permissions.defaultMode to bypassPermissions in its committed .claude/settings.json, causing the trust dialog to be silently skipped on first open. This allowed a user to be placed into a permissive mode without seeing the trust confirmation prompt, making it easier for an attacker-controlled repository to gain tool execution without explicit user consent. This issue has been patched in version 2.1.53.

Severity

7.7 (High)

CVE-2026-25724 (GCVE-0-2026-25724)

Vulnerability from nvd – Published: 2026-02-06 17:53 – Updated: 2026-03-27 21:11

Title

Claude Code Has Permission Deny Bypass Through Symbolic Links

Summary

Claude Code is an agentic coding tool. Prior to version 2.1.7, Claude Code failed to strictly enforce deny rules configured in settings.json when accessing files through symbolic links. If a user explicitly denied Claude Code access to a file (such as /etc/passwd) and Claude Code had access to a symbolic link pointing to that file, it was possible for Claude Code to read the restricted file through the symlink without triggering deny rule enforcement. This issue has been patched in version 2.1.7.

Severity

2.3 (Low)

CVE-2026-25725 (GCVE-0-2026-25725)

Vulnerability from nvd – Published: 2026-02-06 17:53 – Updated: 2026-02-06 19:15

Title

Claude Code Has Sandbox Escape via Persistent Configuration Injection in settings.json

Summary

Claude Code is an agentic coding tool. Prior to version 2.1.2, Claude Code's bubblewrap sandboxing mechanism failed to properly protect the .claude/settings.json configuration file when it did not exist at startup. While the parent directory was mounted as writable and .claude/settings.local.json was explicitly protected with read-only constraints, settings.json was not protected if it was missing. This allowed malicious code running inside the sandbox to create this file and inject persistent hooks (such as SessionStart commands) that would execute with host privileges when Claude Code was restarted. This issue has been patched in version 2.1.2.

Severity

7.7 (High)

Title

Claude Code Vulnerable to Command Injection via Piped sed Command Bypasses File Write Restrictions

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.55, Claude Code failed to properly validate commands using piped sed operations with the echo command, allowing attackers to bypass file write restrictions. This vulnerability enabled writing to sensitive directories like the .claude folder and paths outside the project scope. Exploiting this required the ability to execute commands through Claude Code with the "accept edits" feature enabled. This issue has been patched in version 2.0.55.

Severity

7.7 (High)

CVE-2026-25722 (GCVE-0-2026-25722)

Vulnerability from nvd – Published: 2026-02-06 17:52 – Updated: 2026-02-06 18:42

Title

Claude Code Vulnerable to Command Injection via Directory Change Bypasses Write Protection

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.57, Claude Code failed to properly validate directory changes when combined with write operations to protected folders. By using the cd command to navigate into sensitive directories like .claude, it was possible to bypass write protection and create or modify files without user confirmation. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.57.

Severity

7.7 (High)

Title

Claude Code has a Command Injection in find Command Bypasses User Approval Prompt

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.72, due to an error in command parsing, it was possible to bypass the Claude Code confirmation prompt to trigger execution of untrusted commands through the find command. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.72.

Vulnerability from nvd – Published: 2026-02-03 20:49 – Updated: 2026-02-03 21:22

Title

Cluade Code has a Path Restriction Bypass via ZSH Clobber which Allows Arbitrary File Writes

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.74, due to a Bash command validation flaw in parsing ZSH clobber syntax, it was possible to bypass directory restrictions and write files outside the current working directory without user permission prompts. Exploiting this required the user to use ZSH and the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.74.

Title

Claude Code has a Domain Validation Bypass which Allows Automatic Requests to Attacker-Controlled Domains

Summary

Claude Code is an agentic coding tool. Prior to version 1.0.111, Claude Code contained insufficient URL validation in its trusted domain verification mechanism for WebFetch requests. The application used a startsWith() function to validate trusted domains (e.g., docs.python.org, modelcontextprotocol.io), this could have enabled attackers to register domains like modelcontextprotocol.io.example.com that would pass validation. This could enable automatic requests to attacker-controlled domains without user consent, potentially leading to data exfiltration. This issue has been patched in version 1.0.111.

CVE-2026-21852 (GCVE-0-2026-21852)

Vulnerability from nvd – Published: 2026-01-21 20:42 – Updated: 2026-01-21 21:34

Title

Claude Code Leaks Data via Malicious Environment Configuration Before Trust Confirmation

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.65, vulnerability in Claude Code's project-load flow allowed malicious repositories to exfiltrate data including Anthropic API keys before users confirmed trust. An attacker-controlled repository could include a settings file that sets ANTHROPIC_BASE_URL to an attacker-controlled endpoint and when the repository was opened, Claude Code would read the configuration and immediately issue API requests before showing the trust prompt, potentially leaking the user's API keys. Users on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to version 2.0.65, which contains a patch, or to the latest version.

CVE-2026-40068 (GCVE-0-2026-40068)

Vulnerability from cvelistv5 – Published: 2026-05-05 20:52 – Updated: 2026-05-06 15:24

Title

Claude Code arbitrary code execution via git worktree commondir trust dialog bypass

Summary

In versions 2.1.63 through 2.1.83 of Claude Code, the folder trust determination logic used the git worktree commondir file without validating its contents. An attacker could craft a malicious repository with a commondir file pointing to a path the victim had previously trusted, causing Claude Code to bypass its trust confirmation dialog and immediately execute hooks defined in `.claude/settings.json`. Exploitation requires the victim to clone the malicious repository and run Claude Code within it, and the attacker must know or guess a path the victim had already trusted. This issue has been fixed in version 2.1.84.

CVE-2026-39861 (GCVE-0-2026-39861)

Vulnerability from cvelistv5 – Published: 2026-04-21 00:56 – Updated: 2026-04-21 13:44

Title

Claude Code: Sandbox Escape via Symlink Following Allows Arbitrary File Write Outside Workspace

Summary

Claude Code is an agentic coding tool. Prior to version 2.1.64, Claude Code's sandbox did not prevent sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code subsequently wrote to a path within such a symlink, its unsandboxed process followed the symlink and wrote to the target location outside the workspace without prompting the user for confirmation. This allowed a sandbox escape where neither the sandboxed command nor the unsandboxed app could independently write outside the workspace, but their combination could write to arbitrary locations, potentially leading to code execution outside the sandbox. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window to trigger sandboxed code execution via prompt injection. Users on standard Claude Code auto-update have received this fix automatically. Users performing manual updates are advised to update to version 2.1.64 or later.

Severity

Title

Claude Code: Insecure System-Wide Configuration Loading Enables Local Privilege Escalation on Windows

Summary

Claude Code is an agentic coding tool. In versions prior to 2.1.75 on Windows, Claude Code loaded the system-wide default configuration from C:\ProgramData\ClaudeCode\managed-settings.json without validating directory ownership or access permissions. Because the ProgramData directory is writable by non-administrative users by default and the ClaudeCode subdirectory was not pre-created or access-restricted, a low-privileged local user could create this directory and place a malicious configuration file that would be automatically loaded for any user launching Claude Code on the same machine. Exploiting this would have required a shared multi-user Windows system and a victim user to launch Claude Code after the malicious configuration was placed. This issue has been fixed on version 2.1.75.

Severity

5.4 (Medium)

CVE-2026-33068 (GCVE-0-2026-33068)

Vulnerability from cvelistv5 – Published: 2026-03-20 08:17 – Updated: 2026-03-20 13:48

Title

Claude Code has a Workspace Trust Dialog Bypass via Repo-Controlled Settings File

Summary

Claude Code is an agentic coding tool. Versions prior to 2.1.53 resolved the permission mode from settings files, including the repo-controlled .claude/settings.json, before determining whether to display the workspace trust confirmation dialog. A malicious repository could set permissions.defaultMode to bypassPermissions in its committed .claude/settings.json, causing the trust dialog to be silently skipped on first open. This allowed a user to be placed into a permissive mode without seeing the trust confirmation prompt, making it easier for an attacker-controlled repository to gain tool execution without explicit user consent. This issue has been patched in version 2.1.53.

Severity

7.7 (High)

Title

Claude Code Has Sandbox Escape via Persistent Configuration Injection in settings.json

Summary

Claude Code is an agentic coding tool. Prior to version 2.1.2, Claude Code's bubblewrap sandboxing mechanism failed to properly protect the .claude/settings.json configuration file when it did not exist at startup. While the parent directory was mounted as writable and .claude/settings.local.json was explicitly protected with read-only constraints, settings.json was not protected if it was missing. This allowed malicious code running inside the sandbox to create this file and inject persistent hooks (such as SessionStart commands) that would execute with host privileges when Claude Code was restarted. This issue has been patched in version 2.1.2.

CVE-2026-25724 (GCVE-0-2026-25724)

Vulnerability from cvelistv5 – Published: 2026-02-06 17:53 – Updated: 2026-03-27 21:11

Title

Claude Code Has Permission Deny Bypass Through Symbolic Links

Summary

Claude Code is an agentic coding tool. Prior to version 2.1.7, Claude Code failed to strictly enforce deny rules configured in settings.json when accessing files through symbolic links. If a user explicitly denied Claude Code access to a file (such as /etc/passwd) and Claude Code had access to a symbolic link pointing to that file, it was possible for Claude Code to read the restricted file through the symlink without triggering deny rule enforcement. This issue has been patched in version 2.1.7.

Severity

2.3 (Low)

CVE-2026-25723 (GCVE-0-2026-25723)

Vulnerability from cvelistv5 – Published: 2026-02-06 17:52 – Updated: 2026-02-06 18:40

Title

Claude Code Vulnerable to Command Injection via Piped sed Command Bypasses File Write Restrictions

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.55, Claude Code failed to properly validate commands using piped sed operations with the echo command, allowing attackers to bypass file write restrictions. This vulnerability enabled writing to sensitive directories like the .claude folder and paths outside the project scope. Exploiting this required the ability to execute commands through Claude Code with the "accept edits" feature enabled. This issue has been patched in version 2.0.55.

Severity

7.7 (High)

Title

Claude Code Vulnerable to Command Injection via Directory Change Bypasses Write Protection

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.57, Claude Code failed to properly validate directory changes when combined with write operations to protected folders. By using the cd command to navigate into sensitive directories like .claude, it was possible to bypass write protection and create or modify files without user confirmation. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.57.

Vulnerability from cvelistv5 – Published: 2026-02-03 20:50 – Updated: 2026-02-03 21:19

Title

Claude Code has a Command Injection in find Command Bypasses User Approval Prompt

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.72, due to an error in command parsing, it was possible to bypass the Claude Code confirmation prompt to trigger execution of untrusted commands through the find command. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.72.

Severity

7.7 (High)

Vulnerability from cvelistv5 – Published: 2026-02-03 20:49 – Updated: 2026-02-03 21:22

Title

Cluade Code has a Path Restriction Bypass via ZSH Clobber which Allows Arbitrary File Writes

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.74, due to a Bash command validation flaw in parsing ZSH clobber syntax, it was possible to bypass directory restrictions and write files outside the current working directory without user permission prompts. Exploiting this required the user to use ZSH and the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.74.

CVE-2026-24052 (GCVE-0-2026-24052)

Vulnerability from cvelistv5 – Published: 2026-02-03 20:49 – Updated: 2026-02-04 20:00

Title

Claude Code has a Domain Validation Bypass which Allows Automatic Requests to Attacker-Controlled Domains

Summary

Claude Code is an agentic coding tool. Prior to version 1.0.111, Claude Code contained insufficient URL validation in its trusted domain verification mechanism for WebFetch requests. The application used a startsWith() function to validate trusted domains (e.g., docs.python.org, modelcontextprotocol.io), this could have enabled attackers to register domains like modelcontextprotocol.io.example.com that would pass validation. This could enable automatic requests to attacker-controlled domains without user consent, potentially leading to data exfiltration. This issue has been patched in version 1.0.111.

Severity

CVE-2026-21852 (GCVE-0-2026-21852)

Vulnerability from cvelistv5 – Published: 2026-01-21 20:42 – Updated: 2026-01-21 21:34

Title

Claude Code Leaks Data via Malicious Environment Configuration Before Trust Confirmation

Summary

Claude Code is an agentic coding tool. Prior to version 2.0.65, vulnerability in Claude Code's project-load flow allowed malicious repositories to exfiltrate data including Anthropic API keys before users confirmed trust. An attacker-controlled repository could include a settings file that sets ANTHROPIC_BASE_URL to an attacker-controlled endpoint and when the repository was opened, Claude Code would read the configuration and immediately issue API requests before showing the trust prompt, potentially leaking the user's API keys. Users on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to version 2.0.65, which contains a patch, or to the latest version.

Severity

5.3 (Medium)
