  "description": "Two critical bugs in the self-hosted Postiz social media scheduler, both reported with working PoCs by Anthropic. Postiz signed session, invite and password-reset tokens with one shared secret and no purpose marker, and an extension-refresh route signed request data, so any registered user could forge tokens and become super admin of another organization (CVE-2026-115933, CVSS 9.9). A separate path traversal in post media let a registered user have the worker send any server file, including the JWT secret and env file, to their own Discord server (CVE-2026-115932, CVSS 9.6). Both are fixed in Postiz 2.25.3; self-registration is open by default, so upgrade now.",
