cPanel CVE-2026-41940 actively exploited, authentication bypass enables potential RCE

  • Announced
  • Action required
  • High importance

CVE-2026-41940 affects cPanel control-panel interfaces and has been observed in active exploitation campaigns, with incident activity reported in Australia. The flaw allows an unauthenticated attacker to bypass authentication controls and potentially achieve remote code execution against exposed hosting management panels. Singapore's Cyber Security Agency (CSA) issued an advisory flagging the active exploitation and urging administrators to verify patched status and review internet-exposed control-panel surfaces. Organizations running cPanel-based hosting infrastructure should immediately audit exposed management interfaces, apply available patches, and check for signs of compromise. Given the active exploitation status and the nature of cPanel deployments — often managing large numbers of hosted sites — the blast radius of a successful attack can be significant. Hosting providers and managed service operators should treat remediation as a priority item.
