Authenticated users with Administrator or higher privileges can craft input to instantiate malicious PHP objects. However, the plugin contains no built\u2011in Proxy\u2011Object\u2011Pattern (POP) chain, so the vulnerability alone does not enable arbitrary code execution.

Exploitation requires Administrator\u2011level access, meaning an attacker must already have authenticated session or credentials to the WordPress site. The EPSS score is unavailable and the vulnerability is not catalogued in KEV. Attackers with site admin privileges can inject objects; if a POP chain is present elsewhere on the system, the consequences may include file manipulation, data theft, or code execution. The risk is mitigated only if the site runs a later plugin version without the vulnerability or lacks a compatible POP chain."}}}}, "created": "2026-04-14T16:15:52.630248+00:00", "updated": "2026-04-14T16:30:49.206447+00:00", "vendors": ["shapedplugin", "shapedplugin$PRODUCT$post_grid\\,_post_carousel\\,_\\&_list_category_posts", "wordpress", "wordpress$PRODUCT$wordpress"]}
