CVE-2026-93697· CVE.org (no NVD analysis yet)· CNA hackerone

There is a stored XSS vulnerability allowing arbitrary code execution in the WHM Mass Modify Accounts interface.

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.52% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Webpros cPanel 11.110.0.148, 11.134.0.61, 11.136.0.45; Webpros WP Squared 11.138.1.13.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Webpros cPanel 11.110.0.148, 11.134.0.61, 11.136.0.45; Webpros WP Squared 11.138.1.13 or later.
