CVSS 7.4 · High EPSS 0,46%

Kerentanan Authentication Bypass by Spoofing. Skor CVSS 3.1 7.4 (High) menurut vulncheck.com.

Deskripsi (NVD)

BookStack before 26.05.5 contains an authentication bypass vulnerability in its social login implementation that allows unauthenticated attackers to sign in as arbitrary users by authenticating through a different social provider sharing the same driver_id namespace. Attackers can authenticate at one enabled social provider using a user ID that matches an account linked to a different social provider, bypassing credential verification entirely because the SocialAuthService::handleLoginCallback query ignores the driver column when retrieving linked account records.
