Site compromise via exposed REST deserialization
Published Jul 9, 2024 · Updated Aug 1, 2024
Object injection in SEOPress before 7.9 allows remote attackers to compromise WordPress sites through exposed REST API routes. The posts/{id}/title-description-metas route stores an attacker-supplied serialized title, and the posts/{id}/content-analysis route later unserializes it. The two-step path requires a published post and a suitable PHP gadget chain, and the resulting impact depends on the chain available on the site.
