{"id":"CVE-2026-24845","aliases":["GHSA-9m43-p3cx-w8j5","GO-2026-4392"],"url":"https://o3.security/vulnerability/CVE-2026-24845","summary":"malcontent's OCI image scanning could expose registry credentials","details":"malcontent discovers supply-chain compromises through. context, differential analysis, and YARA. 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.","published":"2026-01-29T21:02:24.371Z","modified":"2026-08-12T03:51:42.730473099Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},"epss":{"score":0.0035,"percentile":0.28504,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/chainguard-dev/malcontent","fixedVersion":"1.20.3"}],"fix":{"url":"https://github.com/chainguard-dev/malcontent/commit/538ed00cdc639d687a4bd1e843a2be0428a3b3e7","label":"chainguard-dev/malcontent@538ed00"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24845.json"},{"type":"ADVISORY","url":"https://github.com/chainguard-dev/malcontent/security/advisories/GHSA-9m43-p3cx-w8j5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24845"},{"type":"FIX","url":"https://github.com/chainguard-dev/malcontent/commit/538ed00cdc639d687a4bd1e843a2be0428a3b3e7"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:42.730473099Z"}}
