      <title>CVE-2026-22728 — sealed-secrets /v1/rotate can widen sealing scope to cluster-wide via attacker-controlled template annotations</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-22728</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Bitnami sealed-secrets&lt;/p&gt;
&lt;p&gt;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 &amp;#34;strict&amp;#34; or
&amp;#34;namespace-wide&amp;#34; constraints, allowing the attacker to retarget and unseal
the secret in any namespace or under any name to recover the plaintext
credentials.&lt;/p&gt;</description>
