{"id":"AZL-91397","summary":"CVE-2026-54369 affecting package acl for versions less than 2.4.0-1","details":"acl before version 2.4.0 contains a symlink traversal vulnerability in the libacl pathname-based functions acl_get_file(), acl_set_file(), acl_extended_file(), and acl_delete_def_file() that allows local attackers to escalate privileges by replacing any pathname component with a symbolic link. Attackers who control any component of a pathname processed by a privileged caller can redirect ACL read or write operations to arbitrary files or directories, enabling unauthorized manipulation of access control lists and local privilege escalation.","modified":"2026-08-30T05:26:50Z","published":"2026-06-29T14:16:57Z","upstream":["CVE-2026-54369"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54369"}],"affected":[{"package":{"name":"acl","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/acl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91397.json"}}],"schema_version":"1.9.0"}
