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.","published":"2023-07-27T18:07:13.283Z","modified":"2026-10-28T02:31:02.166490491Z","cvss":{"score":8.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Go","name":"github.com/crossplane/crossplane","fixedVersion":"1.11.5"},{"ecosystem":"Go","name":"github.com/crossplane/crossplane","fixedVersion":"1.12.3"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/crossplane/crossplane/blob/ac8b24fe739c5d942ea885157148497f196c3dd3/security/ADA-security-audit-23.pdf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/38xxx/CVE-2023-38495.json"},{"type":"ADVISORY","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:02.166490491Z"}}
