CVE-2026-22333Network attack vector

Administrator-level object injection via unsafe deserialization

Published Feb 19, 2026 · Updated Feb 19, 2026

PHP object injection in YITH WooCommerce Compare 3.6.0 and earlier allows remote authenticated users to inject objects through untrusted data. Public advisories do not identify the input field, endpoint, or deserialization call that accepts the attacker-controlled serialized value. Administrator access is required, and harmful effects require a POP chain from another installed plugin or theme; the available chain determines whether file deletion, data disclosure, or code execution follows.
