CVE-2026-1496: Black Duck Coverity

Critical severity, CVSS 9.3. EPSS: 0.5% chance of exploitation in the next 30 days.

Vulnerable versions of Coverity Connect lack an error handler in the authentication logic for command line tooling that makes it vulnerable to an authentication bypass. A malicious actor with access to the /token API endpoint that either knows or guesses a valid username, can use this in a specially crafted HTTP request to bypass authentication. Successful exploitation allows the malicious actor to assume all roles and privileges granted to the valid user’s Coverity Connect account.

Affected products

• Black Duck Coverity: from 2024.3.0, before 2025.12.0 (fixed in 2025.12.0)
