CVE-2026-90768 kevoreilly CVE debrief

Who should care

Defenders responsible for CAPEv2 deployments, especially in environments where multiple users have access to the system, should assess exposure and prioritize remediation. This includes operators, platform administrators, vulnerability management teams, and security teams who need to ensure system integrity and protect against potential exploitation. They should review system configurations, user access controls, and monitoring capabilities to mitigate the

Why it matters

Defenders should prioritize verifying and remediating this vulnerability in CAPEv2 deployments, especially in environments where multiple users have access to the system, as it allows authenticated users to read and delete analyses submitted by other users.

• Authenticated users can read analyses submitted by other users
• Authenticated users can delete arbitrary analyses

Technical summary

CAPEv2 through commit 471ee4b fails to validate task ownership in REST API endpoints, allowing authenticated users to read and delete analyses submitted by other users. Attackers can exploit this vulnerability to enumerate all tasks in the system and delete arbitrary analyses by sending requests to task view and delete endpoints without ownership verification. This could lead to unauthorized data access and deletion, impacting system integrity. The vulnerability has a CVSS score of 8.6, indicating high severity. Defenders should prioritize verifying and remediating this vulnerability in CAPEv2 deployments, especially in environments where multiple users have access to the system.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability in CAPEv2 deployments, especially in environments where multiple users have access to the system.

Recommended defensive actions

• Verify CAPEv2 deployments for the missing ownership check vulnerability
• Remediate vulnerable deployments by updating to a fixed version
• Monitor system logs for potential exploitation attempts
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including its description and CVSS score of 8.6. However, the exact scope of affected deployments and versions requires further verification. The vulnerability affects CAPEv2 through commit 471ee4b, and defenders should verify system configurations and user access controls. Additional sources may be needed to fully understand the vulnerability's impact and to confirm affected versions.
