CVE-2026-82379 Apache Software Foundation CVE debrief

Who should care

Administrators and users of Apache Roller 6.1.5 with AtomPub API enabled and WSSE authentication configured should assess exposure. Operators managing Apache Roller 6.1.5 deployments, platform administrators, vulnerability management teams, and security teams should review and upgrade to Apache Roller 6.1.6 or later. Users with plaintext-compatible password storage configured are at risk and should verify authentication configurations to prevent

Why it matters

CVE-2026-82379 is an authentication bypass vulnerability in Apache Roller 6.1.5 that allows an attacker to capture and replay a valid WSSE digest authentication header to gain AtomPub authority. Only installations with the non-default AtomPub API, WSSE authentication, and plaintext-compatible password storage are affected. Users should upgrade to Apache Roller 6.1.6 or later to remove WSSE as an AtomPub authentication method.

• Verify authentication configurations to prevent unauthorized access
• Upgrade to Apache Roller 6.1.6 or later to remove WSSE as an AtomPub authentication method
• Review and update password storage and authentication methods

Technical summary

CVE-2026-82379 is an authentication bypass vulnerability in Apache Roller 6.1.5. The vulnerability allows an attacker to capture and replay a valid WSSE digest authentication header to gain AtomPub authority. This is possible because the authentication does not enforce nonce uniqueness or timestamp freshness. Only installations that enable the non-default AtomPub API with WSSE authentication and plaintext-compatible password storage are affected.

Defensive priority

Upgrade to Apache Roller 6.1.6 or later to remove WSSE as an AtomPub authentication method.

Recommended defensive actions

• Upgrade to Apache Roller 6.1.6 or later
• Review and update AtomPub API configurations
• Verify password storage and authentication methods
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
