Private Pages access via cross-domain token replay
Published Apr 4, 2022 · Updated Aug 2, 2024
Improper authorization in affected GitLab Pages releases allows remote attackers to read private sites by replaying a stolen session token. A service worker on an attacker-controlled private Pages domain intercepts the OAuth callback at /auth, while the server fails to bind the resulting session cookie to its issuing subdomain. The victim must be signed in, have access to the attacker's private Pages project, and visit that site; the stolen cookie then opens other private Pages sites available to the victim.
