Vulnerability details
The vulnerability allows a low-privileged authenticated attacker to read and overwrite project translations without the required editing or language-specific permissions.
The vulnerability exists due to missing authorization checks in Tolgee's MCP translation tools when they bypass permission checks enforced inside the corresponding REST handlers. A low-privileged authenticated attacker can invoke these tools using credentials with any project scope, including view-only access, to access translation text or overwrite translations in any language.
