Object injection via serialized specific_terms input
Published Aug 18, 2026 · Updated Aug 20, 2026
PHP object injection in Auto Terms in TaxoPress before 3.52.0 allows remote authenticated users to inject PHP objects via crafted specific_terms input. The 3.52.0 fix shows that the specific_terms setting previously accepted serialized strings; TaxoPress added taxopress_sanitize_specific_terms to reject serialized payloads before normalizing that field. Reachability depends on access to TaxoPress Auto Terms management, which the CNA record describes as Editor-level, and follow-on impact depends on whether the WordPress stack provides a usable gadget chain.
