Description

A path traversal vulnerability in the static file route handler allows any unauthenticated user to determine whether files exist anywhere on the server’s filesystem. By sending percent-encoded ../ sequences (%2E%2E%2F) in requests to static file routes, an attacker can check for the existence of files (404 if it doesn’t exist, 403 means it exists).

Recommendation

Update the sillytavern package to the latest compatible version. Followings are version details:

  • Affected version(s): <= 1.16.0
  • Patched version(s): 1.17.0
