Published Updated By the CyberSecBulletin desk

CVE-2026-63158 is a high-severity use of password hash instead of password for authentication vulnerability in Agora Project from Omnispace, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 26.10.0 as the first without the flaw, so updating Agora Project to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.42% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

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.

The underlying weakness: Use of Password Hash Instead of Password for Authentication

The product includes a client that computes a hash of a password and sends the hash to another component, which compares the supplied hash to the hash obtained from a data store of password hashes.
