CVE-2026-54371 | BDVDB-2026-344021 Detail
attr projectattr
Description#
attr before version 2.6.0 contains a symlink traversal vulnerability in the getfattr and setfattr utilities that allows local attackers to escalate privileges by replacing a pathname component with a symbolic link during directory hierarchy traversal. Attackers who control a pathname component can redirect getfattr and setfattr operations to arbitrary files by substituting a symlink, leading to local privilege escalation when getfattr or setfattr is invoked by a privileged process over an attacker-controlled path.
Impact#
Per CVSS v3.1: confidentiality impact high, integrity impact high, availability impact none. Attack vector: local.
Weaknesses#
- CWE-59 Improper Link Resolution Before File Access ('Link Following')
