State changes via non-SameSite authentication cookie
Published Nov 13, 2021 · Updated Aug 3, 2024
CSRF in ShowDoc 2.9.12 and earlier allows remote attackers to submit state-changing requests through an authenticated user's browser. UserController sets the cookie_token authentication cookie without a SameSite attribute, so browsers can attach it to cross-site requests. Exploitation requires an authenticated user to follow attacker-controlled content; the affected action and resulting data change are not publicly specified.
