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.
