Starting in version 0.10.0 and prior to version 1.20.3, malcontent could be made to expose Docker registry credentials if it scanned a specially crafted OCI image reference. malcontent uses google/go-containerregistry for OCI image pulls, which by default uses the Docker credential keychain. A malicious registry could return a `WWW-Authenticate` header redirecting token authentication to an attacker-controlled endpoint, causing credentials to be sent to that endpoint. Version 1.20.3 fixes the issue by defaulting to anonymous auth for OCI pulls."}], "lastModified": "2026-02-20T20:24:15.000", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:chainguard:malcontent:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B26FE904-C57A-4E90-AF6C-21261E98B0F8", "versionEndExcluding": "1.20.3", "versionStartIncluding": "0.1.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
