CVE-2026-63160 Omnispace CVE debrief

Who should care

Defenders responsible for Omnispace Agora Project deployments should assess exposure and prioritize updating to version 26.10.0 or later. This vulnerability allows attackers to authenticate as users without their passwords if they gain access to stored remember-me tokens.

Why it matters

CVE-2026-63160 allows attackers to authenticate as users without their passwords if they gain access to stored remember-me tokens in Omnispace Agora Project before version 26.10.0. Defenders should assess exposure, prioritize updating, and monitor for unauthorized authentication attempts.

• Attackers can authenticate as users without their passwords if they gain access to stored remember-me tokens
• Requires verification of affected versions and remediation priority
• Defenders must monitor for unauthorized authentication attempts
• Updating to version 26.10.0 or later is necessary to fix the vulnerability

Technical summary

The Omnispace Agora Project before version 26.10.0 stores persistent remember-me tokens verbatim server-side, making the stored value identical to the bearer credential held in the user's cookie. This allows attackers who gain access to the stored token, such as through database or backup disclosure, to replay the plaintext value and authenticate as the victim user without needing their password. The vulnerability is characterized by its impact on authentication mechanisms and the potential for unauthorized access. Defenders should focus on updating to version 26.10.0 or later and enhancing monitoring for suspicious authentication attempts.

Defensive priority

High

Recommended defensive actions

• Review and update Omnispace Agora Project to version 26.10.0 or later
• Restrict access to stored remember-me tokens
• Monitor for unauthorized authentication attempts
• 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

Evidence notes
