CVE-2025-1559 is a stored cross-site scripting vulnerability in the clearcodehq CC-IMG-Shortcode WordPress plugin affecting all versions up to 1.1.0. The issue stems from improper neutralization of input during web page generation, specifically insufficient input sanitization and output escaping on the 'img' shortcode attributes. Authenticated attackers with contributor-level permissions or higher can inject arbitrary JavaScript that executes in the context of users viewing the compromised pages. This vulnerability can lead to information disclosure or session hijacking but does not affect availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required, no user interaction, and scope change.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the 'img' shortcode. These scripts execute in the browsers of users who visit the infected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not impact system availability. There are no known exploits in the wild at this time.

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 removing or disabling the CC-IMG-Shortcode plugin if possible. Monitor vendor channels for updates regarding a security patch.
