Title
Apache Airflow: Log server JWT authorization bypass via Python lstrip() character stripping allows cross-Dag log access
Summary
Exploitation requires the attacker to already be an authenticated Airflow worker holding a valid Log-server JWT issued for at least one Dag. Apache Airflow's Log server authorized JWT tokens against Dag IDs by applying Python's `str.lstrip()` to the requested path segment when verifying the JWT's `sub` claim. `str.lstrip()` strips any of a *set* of characters from the left (not a prefix), so a JWT issued for a Dag named e.g. `dag_a` would authorize log access to any other Dag whose name began with any subset of the characters `{d, a, g, _}` (e.g. `dag_attacker`, `aaaa_target`, `_dag_secret`). Such an authenticated worker could enumerate and read worker logs of other Dags whose names happened to share that character-class prefix, leaking task output and error traces beyond the documented per-Dag isolation boundary. Affects deployments relying on per-Dag log-access scoping (multi-team, shared-executor, shared-worker topologies). Users are advised to upgrade to `apache-airflow` 3.2.2 or later.

Title
Open WebUI: Jupyter code execution works despite `ENABLE_CODE_EXECUTION=false` — feature gate bypassed
Summary
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.8.12, the /api/v1/utils/code/execute endpoint executes arbitrary Python code via Jupyter for any verified user, even when the admin has set ENABLE_CODE_EXECUTION=false. The feature gate is not enforced on the API endpoint — the configuration says "disabled" but code still executes. This vulnerability is fixed in 0.8.12.

CVE-2026-45718 (GCVE-0-2026-45718)

Title
Budibase: Row Action Trigger Bypasses View Row Filter Security Boundary Allowing Action on Out-of-Scope Rows
Summary
Budibase is an open-source low-code platform. Prior to 3.38.1, the row action trigger endpoint (POST /api/tables/:sourceId/actions/:actionId/trigger) fails to validate that the user-supplied rowId is within the scope of the view's row filters. A user with access to a filtered view can trigger row actions on any row in the underlying table, including rows explicitly excluded by the view's security filters. This vulnerability is fixed in 3.38.1.

Title
phpMyFAQ - Unauthenticated Information Disclosure via getIdFromSolutionId Permission Bypass
Summary
phpMyFAQ before 4.1.2 contains an information disclosure vulnerability in the getIdFromSolutionId() method that lacks permission filtering, allowing unauthenticated attackers to enumerate restricted FAQ entries and read their titles via the /solution_id_{id}.html endpoint. Attackers can sequentially iterate solution IDs to discover all FAQs including those restricted to specific users or groups, leaking sensitive metadata through redirect Location headers and page canonical links.

CVE-2026-47101 (GCVE-0-2026-47101)

Vulnerability from cvelistv5 – Published: 2026-05-21 20:33 – Updated: 2026-05-23 03:55 X_Open Source

Title
LiteLLM < 1.83.14 Privilege Escalation via API Key Generation
Summary
LiteLLM prior to 1.83.14 allows an authenticated internal_user to create API keys with access to routes that their role does not permit. When generating a key, the allowed_routes field is stored without verifying that the specified routes fall within the user's own permissions. A key created with access to admin-only routes can then be used to reach those routes successfully, bypassing the role-based access controls that would otherwise block the request, enabling full privilege escalation from internal_user to proxy_admin.

CVE-2026-47102 (GCVE-0-2026-47102)

Vulnerability from cvelistv5 – Published: 2026-05-21 20:34 – Updated: 2026-05-23 03:55 X_Open Source
VLAI
Title
LiteLLM < 1.83.10 Privilege Escalation via User Update
Summary
LiteLLM prior to 1.83.10 allows a user to modify their own user_role via the /user/update endpoint. While the endpoint correctly restricts users to updating only their own account, it does not restrict which fields may be changed. A user who can reach this endpoint can set their role to proxy_admin, gaining full administrative access to LiteLLM including all users, teams, keys, models, and prompt history. Users with the org_admin role have legitimate access to this endpoint and can exploit this vulnerability without chaining any additional flaw.

CVE-2026-48064 (GCVE-0-2026-48064)

Title
pam_usb: PAM_RHOST check skipped when deny_remote=false allows XDMCP authentication bypass
Summary
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, when a PAM service is configured with deny_remote=false in pam_usb (commonly done for display managers such as gdm-password or lightdm to bypass process/TTY heuristics for local sessions), the PAM_RHOST check in pusb_do_auth() is also skipped. PAM_RHOST is set by remote daemons (sshd, XDMCP servers) to identify the remote client address. Because the check is gated inside if (opts.deny_remote), a genuine remote XDMCP connection reaches the USB device authentication step instead of being rejected. This vulnerability is fixed in 0.9.1.

CVE-2026-48152 (GCVE-0-2026-48152)

Title
Budibase: Basic app users can exfiltrate stored REST datasource auth by rewriting datasource base URL
Summary
Budibase is an open-source low-code platform. Prior to 3.39.0, the single-datasource GET and PUT routes are guarded by generic TABLE READ, not by Builder/Admin permission or datasource-specific ownership/resource checks. The built-in Basic app user role maps to the WRITE permission set, which includes table read/write and query write. A Basic user can therefore read an existing REST datasource, receive redacted authConfigs values, submit an update that changes only config.url while keeping the redacted placeholders, and trigger an existing saved relative-path REST query. During update, mergeConfigs() restores the old stored secret when it sees the redaction placeholder. During query execution, Budibase prefixes the attacker-controlled datasource config.url to the relative query path and applies the resolved stored auth headers. The result is server-side disclosure of the builder-configured REST Authorization secret to an attacker-controlled listener. This vulnerability is fixed in 3.39.0.

Mitigation

Phase: Architecture and Design

Description:

  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation

Phase: Architecture and Design

Description:

  • Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation ID: MIT-4.4

Phase: Architecture and Design

Strategy: Libraries or Frameworks

Description:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation

Phase: Architecture and Design

Description:

  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation

Phases: System Configuration, Installation

Description:

  • Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
