Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2025-58362)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to improper input validation in the getPath utility function when parsing malformed absolute-form request-uris. A remote attacker can send a specially crafted request to disclose sensitive information.

Exploitation may enable bypass of proxy-level ACLs protecting sensitive endpoints such as /admin, and the impact depends on the application and environment because many standards-compliant runtimes and reverse proxies reject such malformed requests.
