Blocksy

CVE-2026-8365 Jun 09, 08:29 HIGH This Week

Authenticated PHP Object Injection in the Blocksy WordPress theme (versions ≤ 2.1.35) allows contributor-level users to escalate to remote code execution by storing a malicious serialized object in post meta that is later deserialized during the V200 database migration. Wordfence-reported flaw chains weak input sanitization in blocksy_sanitize_post_meta_options() with an unconditional @unserialize() call in SearchReplacer::run_recursively(), triggering RaiiPattern::__destruct() to invoke arbitrary callables via call_user_func(). No public exploit identified at time of analysis, but the low-privilege requirement and high impact make this a meaningful priority for sites running upgraded Blocksy installations.
