Bitnami Sealed Secrets is vulnerable to a scope-widening attack during the secret rotation (/v1/rotate) flow. The rotation handler derives the sealing scope for the newly encrypted output from untrusted spec.template.metadata.annotations present in the input SealedSecret. By submitting a victim SealedSecret to the rotate endpoint with the annotation sealedsecrets.bitnami.com/cluster-wide=true injected into the template metadata, a remote attacker can obtain a rotated version of the secret that is cluster-wide. This bypasses original "strict" or "namespace-wide" constraints, allowing the attacker to retarget and unseal the secret in any namespace or under any name to recover the plaintext credentials.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
