The vulnerability exists due to application generates excessive log entries when parsing form data. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Path traversal (CVE-ID: CVE-2026-24486)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to perform directory traversal attacks.
