CVE-2025-5116 is a stored cross-site scripting vulnerability in the WP Plugin Info Card WordPress plugin. It affects all versions up to and including 5.3.1 and involves improper neutralization of input in the 'containerid' parameter. Authenticated attackers with Contributor-level privileges or higher can exploit this flaw to inject arbitrary web scripts that execute in the context of users viewing the injected pages. The vulnerability results from incomplete remediation of a prior XSS issue (CVE-2025-31835), leading to insufficient input sanitization and output escaping.

Successful exploitation allows authenticated users with Contributor or higher privileges to inject persistent malicious scripts into pages. These scripts execute in the browsers of users who access the compromised pages, potentially leading to session hijacking, unauthorized actions, or other client-side attacks. The vulnerability does not affect availability but impacts confidentiality and integrity of user sessions and data.

No official patch or fix is currently available as no patch links or vendor advisories have been provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the affected plugin to prevent exploitation.
