CVE-2026-7659 is a stored cross-site scripting vulnerability in the Advanced Social Media Icons WordPress plugin by riotweb. It affects all versions up to and including 1.2. The issue is caused by improper neutralization of input during web page generation, specifically insufficient input sanitization and output escaping of user-supplied attributes in the 'social' shortcode. Authenticated users with Contributor-level privileges or higher can exploit this to inject arbitrary scripts that execute in the context of other users viewing the injected pages. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, scope change, and limited confidentiality and integrity impact without availability impact.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who view the compromised pages, potentially leading to session hijacking, defacement, or other client-side impacts. The vulnerability affects confidentiality and integrity but does not impact availability. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the Advanced Social Media Icons plugin if feasible. Monitor official riotweb or WordPress security advisories for updates.
