CrowdStrike has confirmed the widespread exploitation of CVE-2026-41940, an authentication bypass vulnerability in cPanel. The vulnerability was disclosed on April 28, 2026, and exploitation began on April 30, 2026.

A technical blog published on April 29, 2026, provided exploitation guidance for CVE-2026-41940. Attackers modified a purported detection-artifact generator to exploit CVE-2026-41940.

CrowdStrike noted that 91% of vulnerabilities with public POC code were exploited within 48 hours. The publication of POC code is often treated as a 'starting gun' for attackers, who use public vulnerability research as a basis for launching attacks. This dual nature of vulnerability research presents both opportunities and challenges for the security community.
