CVE-2026-1496
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVulnerable 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceCoverity Connect command line tooling has a missing error handler in the authentication logic for the /token API endpoint. An attacker who knows or can guess a valid username can send a specially crafted HTTP request to bypass authentication entirely and assume all roles and privileges of that user's account.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Coverity Connect installation and versionLocate the Coverity Connect installation directory and run 'coverity --version' or check version metadata files in the installation pathAffected if The installed version is any version prior to the patched release containing proper error handling in /token endpoint authentication
-
Verify network exposure of the /token API endpointCheck network configuration and firewall rules to determine if the Coverity Connect web interface (typically on port 8080 or 8443) and specifically the /token endpoint is accessible from untrusted networksAffected if The /token endpoint is exposed to network segments where untrusted users could send HTTP requests
-
Review authentication logs for anomalous requestsExamine Coverity Connect server logs for failed authentication attempts that succeeded unexpectedly, or requests to /token endpoint with valid usernames but missing or malformed credentialsAffected if Logs show authentication successes on /token that lack proper credential submission or show patterns of username enumeration
-
Check for unauthorized role or privilege escalationReview audit logs and user activity records for accounts exhibiting privileges or data access inconsistent with their expected role assignmentsAffected if User sessions or actions are recorded with roles/permissions that do not match the legitimate authentication context for that user
A user is affected if Coverity Connect is running and its /token endpoint is network-accessible to potential attackers, regardless of version, since the vulnerability allows bypassing authentication by knowing a valid username.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch from Synopsys for Coverity Connect to fix the authentication bypass; until patched, consider rate-limiting or restricting access to the /token endpoint to prevent exploitation.
