CVE-2026-10795Public exploitNetwork attack vector

Unauthenticated code execution via zero-key RPC forgery

Published Jun 11, 2026 · Updated Jun 11, 2026

Authentication bypass in TeamUpdraft UpdraftPlus 1.26.4 and earlier allows remote attackers to execute administrator RPC commands. UpdraftPlus_Remote_Communications_V2::wp_loaded accepts a failed RSA decryption result as a predictable all-zero symmetric key, allowing forged encrypted RPC messages to pass processing. Exploitation requires an active UpdraftCentral key or, in paid editions, an active Migrator key; successful commands can upload and activate attacker-controlled plugin code.
