Authenticated object injection via unsafe deserialization

Published Mar 31, 2024 · Updated Apr 28, 2026

PHP object injection in Websupporter Filter Custom Fields & Taxonomies Light 1.05 and earlier allows remote authenticated users to inject objects. Public records do not identify the vulnerable function or input field; they disclose only that untrusted data is deserialized into a PHP object. Contributor-level access is required, and file deletion, sensitive-data retrieval, or code execution also requires a POP chain from another installed plugin or theme.
