CVE-2026-1496: Coverity CLI Authentication Bypass

• Severity: critical (CVSS 9.3 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-03-27 · updated 2026-10-26
• Weakness: CWE-639

Description

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.
