{"id":"CVE-2026-1496","state":"PUBLISHED","title":"Coverity CLI Authentication Bypass","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
