The Ocean Social Sharing plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, social icon titles are not adequately sanitized or escaped, allowing authenticated users with Contributor-level privileges or above to inject arbitrary scripts. These scripts execute in the context of any user who accesses the compromised page, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all versions up to and including 2.2.1. No known exploits are reported in the wild as of the publication date.

An attacker with Contributor-level or higher access can inject malicious JavaScript into pages via social icon titles. This script executes in the browsers of users who visit the infected pages, potentially compromising user sessions or performing unauthorized actions within the context of the affected site. The impact is limited to confidentiality and integrity of user data (low-level impact), with no direct availability impact reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the Ocean Social Sharing plugin if possible. Monitor vendor channels for updates and apply patches promptly once released.
