CVE-2026-73834

Credential disclosure via unredacted wrapper CRs

Published Aug 18, 2026 · Updated Aug 20, 2026

Cleartext exposure of secrets in Red Hat Advanced Cluster Management for Kubernetes 2 allows local users to read credentials from must-gather archives. The ACM must-gather component collects certain wrapper Custom Resources that embed Secret data and writes them into the archive without redaction. Exposure requires an administrator to run must-gather and an attacker to obtain the resulting archive; the documented impact is credential and token disclosure, not data modification or service interruption.
