Hi, The following vulnerability was published for pcs. Unfortunately according to the Red Hat bug, the commit referenced is not yet public? CVE-2026-84828[0]: | A flaw was found in PCS (Pacemaker Configuration System). A local | attacker with membership in the 'haclient' group can exploit the | 'pcs host auth --token' command to read the contents of arbitrary | files on the filesystem, provided the files are shorter than 256 | bytes. The file contents are read with root privileges by the pcsd | daemon and can be exfiltrated by the attacker through subsequent | cluster node communication. This allows disclosure of sensitive data | such as API keys, tokens, or configuration secrets that would | otherwise be inaccessible to the attacker. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
