    Title
    SmarterMail < Build 9777 Stale JWT Role Claim Privilege Escalation via Refresh Token
    Summary
    SmarterMail before build 9777 contains a privilege escalation vulnerability where JWT access and refresh tokens embed a role claim at issuance that is not revalidated against the account's current role when redeemed through POST /api/v1/auth/refresh-token. Attackers who capture a refresh token issued before an administrator demotion, or a demoted user whose session was not actively polling at the time of demotion, can replay the stale token to obtain a new access token retaining the higher-privilege role (such as DomainAdmin or SysAdmin) until natural token expiry.

    Title
    SmarterMail < Build 9777 Stored Mutation XSS via MathML Foreign Content
    Summary
    SmarterMail before build 9777 contains a stored mutation cross-site scripting vulnerability that allows remote attackers to inject executable script by placing payloads inside a <style> element nested within MathML foreign content (<math><mtext><mglyph>), which the custom HTML sanitizer treats as inert CDATA text but browsers reparse as live markup. Attackers can deliver a crafted calendar (iCal) message containing an <img src=x onerror=...> payload that executes automatically in the recipient's webmail session at /interface/message-iframe when the message is opened, enabling script execution and data exfiltration unconstrained by the interface's permissive Content-Security-Policy.

    CVE-2026-104082 (GCVE-0-2026-104082)

    Title
    SmarterMail < Build 9777 SysAdmin Remote Code Execution via Volume Mount
    Summary
    SmarterMail before build 9777 contains a remote code execution vulnerability that allows an attacker holding a SysAdmin-scoped access token to bypass the Volume Mount script-directory containment control by provisioning a new mail domain with an arbitrary FileStore root path inside the trusted Scripts directory via the domain-put endpoint. Attackers can disclose the Scripts path through the AddOrUpdateMount endpoint, clear the upload extension blacklist via the global-mail endpoint, then upload a malicious script through the ordinary mail file-storage upload API so that saving a CommandMount triggers RunScript before validation, resulting in a reverse shell executing as the SmarterMail service account with SYSTEM-level privileges.

    CVE-2026-40514 (GCVE-0-2026-40514)

    Vulnerability from nvd – Published: 2026-04-27 14:21 – Updated: 2026-07-14 20:00
    VLAI
    Title
    SmarterTools SmarterMail < Build 9610 Cryptographic Weakness via Weak RNG
    Summary
    SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000 possible values. An unauthenticated attacker can use the attachment download endpoint as an oracle to determine the seed in use and derive encryption keys and initialization vectors to forge sharing tokens for arbitrary emails, attachments, or file storage contents without prior access to the targeted content.

    CVE-2026-25067 (GCVE-0-2026-25067)

    Vulnerability from nvd – Published: 2026-01-29 03:38 – Updated: 2026-03-05 01:30

    Title
    SmarterTools SmarterMail < Build 9518 Unauthenticated background-of-the-day Path Coercion
    Summary
    SmarterTools SmarterMail versions prior to build 9518 contain an unauthenticated path coercion vulnerability in the background-of-the-day preview endpoint. The application base64-decodes attacker-supplied input and uses it as a filesystem path without validation. On Windows systems, this allows UNC paths to be resolved, causing the SmarterMail service to initiate outbound SMB authentication attempts to attacker-controlled hosts. This can be abused for credential coercion, NTLM relay attacks, and unauthorized network authentication.

    CVE-2026-23760 (GCVE-0-2026-23760)

    Vulnerability from nvd – Published: 2026-01-22 14:35 – Updated: 2026-08-04 03:56 X_Known Exploited Vulnerability
    VLAI CISA Shadowserver Previdian
    Title
    SmarterTools SmarterMail < Build 9511 Authentication Bypass via Password Reset API
    Summary
    SmarterTools SmarterMail versions prior to build 9511 contain an authentication bypass vulnerability in the password reset API. The force-reset-password endpoint permits anonymous requests and fails to verify the existing password or a reset token when resetting system administrator accounts. An unauthenticated attacker can supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance. NOTE: SmarterMail system administrator privileges grant the ability to execute operating system commands via built-in management functionality, effectively providing administrative (SYSTEM or root) access on the underlying host.

    Vulnerability from cvelistv5 – Published: 2026-10-09 15:08 – Updated: 2026-10-09 19:38
    VLAI
    Title
    SmarterMail < Build 9777 Stale JWT Role Claim Privilege Escalation via Refresh Token
    Summary
    SmarterMail before build 9777 contains a privilege escalation vulnerability where JWT access and refresh tokens embed a role claim at issuance that is not revalidated against the account's current role when redeemed through POST /api/v1/auth/refresh-token. Attackers who capture a refresh token issued before an administrator demotion, or a demoted user whose session was not actively polling at the time of demotion, can replay the stale token to obtain a new access token retaining the higher-privilege role (such as DomainAdmin or SysAdmin) until natural token expiry.

    Title
    SmarterMail < Build 9777 Stored Mutation XSS via MathML Foreign Content
    Summary
    SmarterMail before build 9777 contains a stored mutation cross-site scripting vulnerability that allows remote attackers to inject executable script by placing payloads inside a <style> element nested within MathML foreign content (<math><mtext><mglyph>), which the custom HTML sanitizer treats as inert CDATA text but browsers reparse as live markup. Attackers can deliver a crafted calendar (iCal) message containing an <img src=x onerror=...> payload that executes automatically in the recipient's webmail session at /interface/message-iframe when the message is opened, enabling script execution and data exfiltration unconstrained by the interface's permissive Content-Security-Policy.

    Title
    SmarterMail < Build 9777 SysAdmin Remote Code Execution via Volume Mount
    Summary
    SmarterMail before build 9777 contains a remote code execution vulnerability that allows an attacker holding a SysAdmin-scoped access token to bypass the Volume Mount script-directory containment control by provisioning a new mail domain with an arbitrary FileStore root path inside the trusted Scripts directory via the domain-put endpoint. Attackers can disclose the Scripts path through the AddOrUpdateMount endpoint, clear the upload extension blacklist via the global-mail endpoint, then upload a malicious script through the ordinary mail file-storage upload API so that saving a CommandMount triggers RunScript before validation, resulting in a reverse shell executing as the SmarterMail service account with SYSTEM-level privileges.

    CVE-2026-40514 (GCVE-0-2026-40514)

    Vulnerability from cvelistv5 – Published: 2026-04-27 14:21 – Updated: 2026-07-14 20:00
    VLAI
    Title
    SmarterTools SmarterMail < Build 9610 Cryptographic Weakness via Weak RNG
    Summary
    SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000 possible values. An unauthenticated attacker can use the attachment download endpoint as an oracle to determine the seed in use and derive encryption keys and initialization vectors to forge sharing tokens for arbitrary emails, attachments, or file storage contents without prior access to the targeted content.

    CVE-2026-25067 (GCVE-0-2026-25067)

    Vulnerability from cvelistv5 – Published: 2026-01-29 03:38 – Updated: 2026-03-05 01:30

    Title
    SmarterTools SmarterMail < Build 9518 Unauthenticated background-of-the-day Path Coercion
    Summary
    SmarterTools SmarterMail versions prior to build 9518 contain an unauthenticated path coercion vulnerability in the background-of-the-day preview endpoint. The application base64-decodes attacker-supplied input and uses it as a filesystem path without validation. On Windows systems, this allows UNC paths to be resolved, causing the SmarterMail service to initiate outbound SMB authentication attempts to attacker-controlled hosts. This can be abused for credential coercion, NTLM relay attacks, and unauthorized network authentication.

    CVE-2026-23760 (GCVE-0-2026-23760)

    Vulnerability from cvelistv5 – Published: 2026-01-22 14:35 – Updated: 2026-08-04 03:56 X_Known Exploited Vulnerability
    VLAI CISA Shadowserver Previdian
    Title
    SmarterTools SmarterMail < Build 9511 Authentication Bypass via Password Reset API
    Summary
    SmarterTools SmarterMail versions prior to build 9511 contain an authentication bypass vulnerability in the password reset API. The force-reset-password endpoint permits anonymous requests and fails to verify the existing password or a reset token when resetting system administrator accounts. An unauthenticated attacker can supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance. NOTE: SmarterMail system administrator privileges grant the ability to execute operating system commands via built-in management functionality, effectively providing administrative (SYSTEM or root) access on the underlying host.
