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.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bitnami/sealed-secrets","events":[{"introduced":"7f8477cf1ebc23f00a23f19e9b776c88bb7ea0c4"},{"fixed":"97e5023c97fa29a5a91706c6d140851fa282bae7"}],"database_specific":{"extracted_events":[{"introduced":"0.35.0"},{"fixed":"<0.36.0"}],"source":"AFFECTED_FIELD"}}],"versions":["helm-v2.18.1","v0.35.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-22728.json"}}],"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"}],"database_specific":{"cna_assigner":"vmware","cwe_ids":["CWE-284"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22728.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"}]}
