CVE-2026-67399 Sep 14, 20:53 CRITICAL PATCH Act Now

Remote code execution in WebPros WHMCS allows unauthenticated network attackers to run arbitrary code on affected installations by feeding crafted serialized data into a code path that deserializes untrusted input (CWE-502). All WHMCS builds from 9.0.0 up to (but not including) 9.0.8, and from 8.0.0 up to (but not including) 8.13.7, are affected; the vendor vector (PR:N/UI:N/AC:L) indicates no authentication or user interaction is required and that default configurations may be exposed, although the specific vulnerable endpoint or feature is not named in the advisory. No public exploit identified at time of analysis - CISA's SSVC assessment records Exploitation: none and EPSS is 0.69% (51st percentile), but the SSVC Technical Impact is rated total and Automatable is yes, so patching should be treated as high priority.
