Incorrect Authorization

OpenClaw versions prior to 2026.2.22 with the optional BlueBubbles plugin contain an access control bypass vulnerability where empty allowFrom configuration causes dmPolicy pairing and allowlist restrictions to be ineffective. Remote attackers can send direct messages to BlueBubbles accounts by exploiting the misconfigured allowlist validation logic to bypass intended sender authorization checks.Show less

Mattermost versions 10.11.x <= 10.11.10 fail to properly validate permission requirements in the team member roles API endpoint which allows team administrators to demote members to guest role. Mattermost Advisory ID: MMSA-2025-00531Show less

Craft CMS is a content management system (CMS). From version 4.0.0-RC1 to before version 4.17.6 and from version 5.0.0-RC1 to before version 5.9.12, a low-privilege user (or an unauthenticated user who has been sent a shared URL) can escalate their privileges to admin by abusing UsersController->actionImpersonateWithToken. This issue has been patched in versions 4.17.6 and 5.9.12.Show less

Mattermost versions 11.3.x <= 11.3.0, 11.2.x <= 11.2.2 fail to verify run_create permission for empty playbookId, which allows team members to create unauthorized runs via the playbook run API. Mattermost Advisory ID: MMSA-2025-00542Show less

FastMCP is the standard framework for building MCP applications. Prior to version 2.14.2, the server does not properly respect the resource parameter submitted by the client in the authorization and token request. Instead of issuing the token explicitly for the MCP server, the token is issued for the base_url passed to the OAuthProxy during initialization. This issue has been patched 2.14.2.Show less

Mattermost versions 11.3.x <= 11.3.0, 11.2.x <= 11.2.2, 10.11.x <= 10.11.10 fail to properly enforce read permissions in search API endpoints which allows guest users without read permissions to access posts and files in channels via search API requests. Mattermost Advisory ID: MMSA-2025-00554Show less

Mattermost versions 10.11.x <= 10.11.10 fail to validate user's authentication method when processing account auth type switch which allows an authenticated attacker to change account password without confirmation via falsely claiming a different auth provider.. Mattermost Advisory ID: MMSA-2026-00583Show less

Mattermost versions 11.3.x <= 11.3.0, 11.2.x <= 11.2.2, 10.11.x <= 10.11.10 fail to validate team-specific upload_file permissions which allows a guest user to post files in channels where they lack upload_file permission via uploading files in a team where they have permission and reusing the file metadata in a POST request to a different team. Mattermost Advisory ID: MMSA-2025-00553Show less

AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. In 1.11.1 and earlier, in multi-user mode, AnythingLLM blocks suspended users on the normal JWT-backed session path, but it does not block them on the browser extension API key path. If a user already has a valid brx-... browser extension API key, that key continues to work after suspension. As a result, a suspended user can still access browser extension endpoints, read reachable workspace metadata, and continue upload or embed operations even though normal authenticated requests are rejected.Show less

AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. In 1.11.1 and earlier, The two generic system-preferences endpoints allow manager role access, while every other surface that touches the same settings is restricted to admin only. Because of this inconsistency, a manager can call the generic endpoints directly to read plaintext SQL database credentials and overwrite admin-only global settings such as the default system prompt and the Community Hub API key.Show less

Mattermost versions 11.3.x <= 11.3.0, 11.2.x <= 11.2.2, 10.11.x <= 10.11.10 fail to restrict plugin installation on CI test instances with default admin credentials which allows an unauthenticated attacker to achieve remote code execution and exfiltrate sensitive configuration data including AWS and SMTP credentials via uploading a malicious plugin after changing the import directory. Mattermost Advisory ID: MMSA-2025-00528Show less

PyJWT is a JSON Web Token implementation in Python. Prior to 2.12.0, PyJWT does not validate the crit (Critical) Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT does not understand, the library accepts the token instead of rejecting it. This violates the MUST requirement in the RFC. This vulnerability is fixed in 2.12.0.Show less

Gokapi is a self-hosted file sharing server with automatic expiration and encryption support. Prior to 2.2.4, An insufficient authorization check in the file replace API allows a user with only list visibility permission (UserPermListOtherUploads) to delete another user's file by abusing the deleteNewFile flag, bypassing the requirement for UserPermDeleteOtherUploads. This vulnerability is fixed in 2.2.4.Show less

Tinyauth is an authentication and authorization server. Prior to 5.0.3, the OIDC token endpoint does not verify that the client exchanging an authorization code is the same client the code was issued to. A malicious OIDC client operator can exchange another client's authorization code using their own client credentials, obtaining tokens for users who never authorized their application. This violates RFC 6749 Section 4.1.3. This vulnerability is fixed in 5.0.3.Show less

A security vulnerability has been detected in projectsend up to r1945. The affected element is an unknown function of the component AJAX Endpoints. The manipulation leads to missing authorization. The attack can be initiated remotely. The identifier of the patch is 35dfd6f08f7d517709c77ee73e57367141107e6b. To fix this issue, it is recommended to deploy a patch.Show less

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.1, sensitivity checks for group encounters are broken because the code only consults form_encounter for sensitivity, while group encounters store sensitivity in form_groups_encounter. As a result, sensitivity is never correctly applied to group encounters, and users who should be restricted from viewing sensitive (e.g. mental health) encounters can view them. This vulnerability is fixed in 8.0.0.1.Show less

Copyparty is a portable file server. Prior to 1.20.12, there was a missing permission-check in the shares feature (the shr global-option). This vulnerability only applies when the shares feature is used for the specific purpose of creating a share of just a single file inside a folder or either the FTP or SFTP server is enabled, and also made publicly accessible. Given these conditions, when a user is browsing a share through either FTP or SFTP (not http or https), they can gain read-access to the remaining files inside the shared folder by guessing/bruteforcing the filenames. It was not possible to descend into subdirectories in this manner; only the sibling files were accessible. This vulnerability is similar to CVE-2025-58753 which was previously fixed for HTTP and HTTPS, but not for FTP. The FTPS server did not yet exist at that time. This vulnerability is fixed in 1.20.12.Show less

OliveTin gives access to predefined shell commands from a web interface. In 3000.10.2 and earlier, OliveTin’s live EventStream broadcasts execution events and action output to authenticated dashboard subscribers without enforcing per-action authorization. A low-privileged authenticated user can receive output from actions they are not allowed to view, resulting in broken access control and sensitive information disclosure.Show less

StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.3.1, the S3 storage manager's isAuthorized() function is declared async (returns Promise<boolean>) but is called without await in both the POST and PUT handlers. Since a Promise object is always truthy in JavaScript, !isAuthorized(type) always evaluates to false, completely bypassing the authorization check. Any authenticated user with the lowest visitor role can upload, delete, rename, and list all files in the S3 bucket. This vulnerability is fixed in 0.3.1.Show less
