The HTTP Basic Authentication modules in ((OTRS)) Community Edition 6 and prior accept the authenticated username from either the REMOTE_USER or HTTP_REMOTE_USER environment variable. In CGI and mod_perl based deployments, HTTP request headers may be mapped to corresponding HTTP_* environment variables, so an unauthenticated remote attacker can supply a crafted Remote-User request header which is exposed to the application as HTTP_REMOTE_USER. When HTTP Basic Authentication is configured as the authentication backend, OTRS trusts this value as an already authenticated username and does not perform an additional password verification.
- CVE-2026-78357Critical
In OTRS, previously issued authentication tokens (JWT) are not immediately invalidated when an agent or customer user account is deactivated or its password is changed. A token may remain valid until its regular expiration time, approximately 16 hours. An attacker who previously obtained a valid token can continue to access OTRS with the privileges of the affected account.

- CVE-2026-108860Critical
BotSharp through 5.2.0 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to forge bearer tokens using the hard-coded Jwt:Key in WebStarter appsettings.json. Attackers can sign tokens with the committed HMAC secret and fixed botsharp issuer and audience to impersonate any known user, including administrators, on Authorize-protected API routes.
- CVE-2026-108753Critical
Agnaistic agnai through 1.0.555 contains a hard-coded credentials vulnerability in self-host.docker-compose.yml, which sets a fixed admin password and public JWT secret. Unauthenticated attackers can log in as admin or sign their own JWT with admin: true to impersonate users, reset passwords, and change server configuration.
- CVE-2026-108576Critical
A vulnerability was found in TOZED X300 up to 6.01.3. This vulnerability affects the function process_ping of the component IPPingDiagnostics Handler.

Original NVD description (English source)
Starting with Firefox 142, it was possible for a compromised child process to trigger a use-after-free in the GPU or browser process using WebGPU-related IPC calls. This may have been usable to escape the child process sandbox. This vulnerability was fixed in Firefox 144.0.2.
