CVE-2025-61779
HighCVSS 8.7Exploitation Probability (EPSS)
Low risk27th percentile - higher than 27% of all known CVEs
Summary
The Trustee project in Confidential Containers before version 0.15.0 did not check if the kbs-client submitting a request to the attestation-policy endpoint was authenticated. This allowed any kbs-client to change the attestation policy.
Risk Assessment
An unauthenticated client can alter the attestation policy, potentially compromising the integrity of the attestation process and leading to exposure of confidential data.
Recommendation
Upgrade Trustee to version 0.15.0 or later, which fixes the issue. Ensure client authentication is enforced.

Original NVD description (English source)
Confidential Containers's Trustee project contains tools and components for attesting confidential guests and providing secrets to them. In versions prior to 0.15.0, the attestation-policy endpoint didn't check if the kbs-client submitting the request was actually authenticated (had the right key). This allowed any kbs-client to actually change the attestation policy. Version 0.15.0 fixes the issue.
