CVE-2026-1755 is a stored cross-site scripting vulnerability in the Menu Icons by ThemeIsle WordPress plugin affecting all versions up to 0.13.20. The issue stems from improper neutralization of input in the '_wp_attachment_image_alt' post meta, allowing authenticated users with Author-level access or higher to inject arbitrary web scripts. These scripts execute when other users access the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity) with network attack vector, low attack complexity, privileges required, no user interaction, and impacts confidentiality and integrity with no availability impact.

An attacker with Author-level or higher privileges can inject persistent malicious scripts into pages via the '_wp_attachment_image_alt' meta field. When other users view these pages, the scripts execute in their browsers, potentially compromising user sessions or data confidentiality and integrity. There is no indication of availability impact. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Author-level access to trusted users only and consider disabling or removing the vulnerable plugin if possible.
