{"id":"GHSA-pj4x-2xr5-w87m","summary":"Possible image tampering from missing image validation for Packages","details":"### Impact\n\nCrossplanes image backend does not validate the byte contents of Crossplane packages. As such, Crossplane does not detect if an attacker has tampered with a Package.\n\n### Patches\n\nThe problem has been fixed in 1.11.5, 1.12.3 and 1.13.0, all the supported versions of Crossplane at the time of writing.\n\n### Workarounds\n\nOnly using images from trusted sources and keeping Package editing/creating privileges to administrators only, which should be both considered already best practices.\n\n### References\n\nSee `ADA-XP-23-11` in the Security Audit's [report](https://github.com/crossplane/crossplane/blob/ac8b24fe739c5d942ea885157148497f196c3dd3/security/ADA-security-audit-23.pdf).\n\n### Credits\n\nThis was reported as `ADA-XP-23-11` by @AdamKorcz and @DavidKorczynski from Ada Logic and facilitated by OSTIF as part of the Security Audit sponsored by CNCF.","aliases":["BIT-crossplane-2023-38495","CVE-2023-38495","GO-2023-1980"],"modified":"2026-07-17T21:16:23.170111981Z","published":"2023-07-28T15:33:38Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2023-07-28T15:33:38Z","nvd_published_at":"2023-07-27T19:15:10Z","cwe_ids":["CWE-20"]},"references":[{"type":"WEB","url":"https://github.com/crossplane/crossplane/security/advisories/GHSA-pj4x-2xr5-w87m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-38495"},{"type":"PACKAGE","url":"https://github.com/crossplane/crossplane"},{"type":"WEB","url":"https://github.com/crossplane/crossplane/blob/ac8b24fe739c5d942ea885157148497f196c3dd3/security/ADA-security-audit-23.pdf"}],"affected":[{"package":{"name":"github.com/crossplane/crossplane","ecosystem":"Go","purl":"pkg:golang/github.com/crossplane/crossplane"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.11.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/07/GHSA-pj4x-2xr5-w87m/GHSA-pj4x-2xr5-w87m.json"}},{"package":{"name":"github.com/crossplane/crossplane","ecosystem":"Go","purl":"pkg:golang/github.com/crossplane/crossplane"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.12.0"},{"fixed":"1.12.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/07/GHSA-pj4x-2xr5-w87m/GHSA-pj4x-2xr5-w87m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
