CVE-2026-63158 Oct 13, 20:17 CRITICAL PATCH Act Now

Authentication bypass in Omnispace Agora Project before 26.10.0 allows anyone holding a user's stored bcrypt password hash to log in as that user - including administrators - by replaying the hash inside the legacy AGORAP_LOG/AGORAP_PASS cookies, never needing the plaintext password. The flaw maps to CWE-836 (use of a password hash instead of the password) and is scored 9.1 in CVSS 4.0 with PR:N, meaning no application login is required to launch the attack; however, the practical gate is a prerequisite credential disclosure, since the attacker must first obtain a valid hash from the Agora credential store (database compromise, exposed backup, or SQL injection), which is why the AC:H assessment applies. The vendor addressed it in release 26.10.0 (vendor-released patch: 26.10.0); no public exploit code has been identified at time of analysis and no EPSS score was supplied.

CVE-2026-9222 Jun 26, 00:16 CRITICAL Act Now

Authentication bypass in the Setracker2 Android companion app (com.tgelec.setracker) versions 3.1.5 and prior lets an attacker who possesses a user's stored password hash authenticate directly to the backend and gain full account access. Because the backend treats the password hash itself as the secret credential, the hash is password-equivalent and does not need to be cracked back to plaintext. No public exploit identified at time of analysis; the issue was disclosed through CISA/ICS-CERT (advisory VA-26-176-01) and carries a high CVSS 4.0 score of 9.2.

CVE-2025-64471 Dec 09, 18:16 HIGH This Week

FortiWeb appliances running versions 8.0.0-8.0.1, 7.6.0-7.6.5, 7.4.0-7.4.10, 7.2.0-7.2.11, or 7.0.0-7.0.11 accept a stored password hash as a direct authentication credential, enabling an attacker who has obtained a valid hash out-of-band (e.g., from a leaked configuration or backup) to authenticate as that user via crafted HTTP/HTTPS requests without knowing the cleartext password. The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N (base 7.5 HIGH) indicates a network-reachable, low-complexity, unauthenticated flaw with high integrity impact; the primary hurdle is acquiring the hash, and the primary exposure is a network-reachable FortiWeb management interface. No public exploit identified at time of analysis.
