CVE-2026-49768 CRITICAL Act Now

Unauthenticated PHP Object Injection in the Happyforms WordPress plugin (versions <= 1.26.13) allows remote attackers to deliver attacker-controlled serialized objects that get deserialized by the plugin, potentially leading to remote code execution, file manipulation, or data compromise on the underlying WordPress site. No public exploit identified at time of analysis, but the CVSS 9.8 rating and unauthenticated network attack vector make this a high-priority issue for any site running the plugin. Reported by Patchstack with a corresponding advisory in their WordPress vulnerability database.
