Published Feb 26, 2026 CWE-284 EPSS 0.35% (28th pctl)

Overview

CVE-2026-22728 is a medium-severity vulnerability. It was published on February 26, 2026 and has a CVSS 3.1 base score of 4.9 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.9, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical Description

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.

Remediation
