cPanel/WHM Patches Three New Vulnerabilities Including CVSS 8.8 Code Execution and Privilege Escalation
cPanel has released security updates addressing three new vulnerabilities distinct from the previously covered CVE-2026-41940 zero-day: CVE-2026-29202 (CVSS 8.8, Perl code execution), CVE-2026-29203 (CVSS 8.8, symlink-based privilege escalation), and CVE-2026-29201 (CVSS 4.3, arbitrary file read). Web hosting providers running cPanel/WHM should apply the updates urgently given the platform's current elevated threat posture following mass exploitation in May 2026.

CVE-2026-41940, a CVSS 9.8 authentication bypass in cPanel and WHM web hosting control panel software, was exploited in the wild before the vendor issued a patch. All versions from 11.40 onwards are affected. Proof-of-concept code is now public. Web hosting providers, managed service providers, and any organisation running cPanel/WHM for server management should apply the emergency patch immediately.
