The rotation handler derives the\nsealing scope for the newly encrypted output from untrusted\nspec.template.metadata.annotations present in the input SealedSecret.\nBy submitting a victim SealedSecret to the rotate endpoint with the\nannotation sealedsecrets.bitnami.com/cluster-wide=true injected into the\ntemplate metadata, a remote attacker can obtain a rotated version of the\nsecret that is cluster-wide. This bypasses original \"strict\" or\n\"namespace-wide\" constraints, allowing the attacker to retarget and unseal\nthe secret in any namespace or under any name to recover the plaintext\ncredentials.","published":"2026-02-26T00:50:00.863Z","modified":"2026-07-31T18:30:13.393421572Z","cvss":{"score":4.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/bitnami-labs/sealed-secrets","fixedVersion":"0.36.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22728.json"},{"type":"ADVISORY","url":"https://github.com/bitnami-labs/sealed-secrets/security/advisories/GHSA-465p-v42x-3fmj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22728"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-31T18:30:13.393421572Z"}}
