CVE-2026-58047 is an HTTP request smuggling vulnerability in cPanel that could allow attackers to cause a leak of credentials. HTTP request smuggling typically exploits discrepancies in how front-end and back-end servers parse HTTP requests, potentially enabling unauthorized access or data leakage. This vulnerability is classified under CWE-444. There is no explicit information on affected versions or available patches. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, and limited confidentiality and integrity impact, with high scope impact. No known exploits in the wild have been reported.

The vulnerability may allow an attacker to leak credentials by exploiting HTTP request smuggling in cPanel. This could lead to unauthorized disclosure of sensitive authentication information. However, the impact is limited to credential leakage without direct evidence of further privilege escalation or system compromise. No known active exploitation has been reported.
