Exploitation Probability (EPSS)

Low risk
0.37%

31th percentile - higher than 31% of all known CVEs

Summary

Yeti through 2.11.0 fails to validate caller permissions in the DELETE /api/v2/rbac/{id} endpoint, allowing users with read access to delete access control relationships. Attackers can revoke the owner's grant and permanently lock legitimate owners out of objects.

Risk Assessment

Low-privileged users can modify access control, revoking owners' rights and causing permanent loss of access to objects. This leads to a breach of data integrity and availability.

Recommendation

Upgrade Yeti to a version newer than 2.11.0 and implement caller permission validation in the DELETE /api/v2/rbac/{id} endpoint.
