Authentication Bypass and RCE in UpdraftPlus WordPress Plugin
CVE-2026-10795 is a critical authentication bypass vulnerability in the UpdraftPlus: WP Backup & Migration Plugin for WordPress affecting all versions up to and including 1.26.4. The flaw is in the UpdraftPlus_Remote_Communications_V2::wp_loaded function and stems from insufficient validation of the remote communications message format used by UpdraftCentral-related RPC handling. According to the provided content, signature verification can be bypassed and unchecked decryption return values can collapse to a predictable all-zero encryption key. As a result, an unauthenticated attacker can forge arbitrary remote procedure call messages that are accepted and executed as the connected administrator. The described attack path includes issuing RPC commands to upload and activate a malicious plugin, which then leads to remote code execution on the target WordPress site.
