CVE-2026-75109 determined-ai CVE debrief

Who should care

Defenders and administrators of Determined deployments should assess exposure and prioritize verification of API endpoint authorization. This includes reviewing API handler configurations and ensuring proper authorization for task management. Affected operator, platform, vulnerability-management, and security-team impact should be considered when assessing exposure and prioritizing verification.

Why it matters

CVE-2026-75109 allows authenticated attackers to disrupt other users' workloads by terminating, pausing, or unpausing tasks they do not own. Defenders should assess exposure, prioritize verification of API endpoint authorization, and review API handler configurations.

• Disruption of user workloads through task termination, pause, or unpause
• Potential for lateral movement or privilege escalation
• Need for verification of API endpoint authorization
• Possible impact on system availability and user productivity

Technical summary

Determined fails to authorize requests on the generic task kill, pause, and unpause endpoints in the API handlers. Authenticated attackers can disrupt other users' workloads by terminating, pausing, or unpausing tasks they do not own. The vulnerability affects Determined deployments, and defenders should assess exposure and prioritize verification of API endpoint authorization. The CVE record and NVD entry provide details on the vulnerability, but additional verification is required for versions, exploitation, impact, or remediation.

Defensive priority

Authenticated attackers can disrupt other users' workloads by terminating, pausing, or unpausing tasks they do not own. Defenders should assess exposure and prioritize verification of API endpoint authorization.

Recommended defensive actions

• Verify API endpoint authorization for task management
• Assess exposure of Determined deployments
• Review and update API handler configurations
• 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

The CVE record and NVD entry provide details on the vulnerability. However, the corpus does not establish versions, exploitation, impact, or remediation, which require verification from the supplied official sources.
