EUVDB-ID: #VU59689
Risk: Medium
CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-21682
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when flatpak-builder applies "finish-args" last in the build. A remote authenticated attacker can send a specially crafted HTTP request and create arbitrary files on the system.
MitigationUpdate the affected package flatpak to the latest version.
