CVE-2026-63158

Omnispace Agora Project < 26.10.0 Pass-the-Hash Authentication Bypass via Cookies

Assigner: VulnCheck
Reserved: 15.07.2026 Published: 13.10.2026 Updated: 14.10.2026

Omnispace Agora Project before 26.10.0 contains an authentication bypass vulnerability that allows attackers possessing a user's stored bcrypt password hash to authenticate as that user without knowing the actual password, caused by the legacy AGORAP_LOG/AGORAP_PASS cookie mechanism treating the stored hash as a directly replayable bearer credential. Attackers can set the AGORAP_LOG/AGORAP_PASS cookies with a stolen password hash to impersonate any user, including administrators, and gain unauthorized access to the application.
