CVE-2025-49242 describes a stored cross-site scripting vulnerability in the sevenspark Bellows Accordion Menu plugin (versions up to 1.4.3). The issue is caused by improper neutralization of input during web page generation, which allows an attacker with low privileges to inject malicious scripts that are stored and later executed in the context of users viewing the affected pages. The vulnerability has a CVSS 3.1 score of 6.5, reflecting medium severity with network attack vector, low attack complexity, required privileges, and user interaction. The vulnerability impacts confidentiality, integrity, and availability to a limited degree. No patch or vendor advisory is currently available, and no known exploitation has been reported.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of users visiting pages using the vulnerable Bellows Accordion Menu plugin. This can lead to limited confidentiality, integrity, and availability impacts such as session hijacking, defacement, or denial of service. However, exploitation requires user interaction and low privileges, which somewhat limits the risk. 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, users should consider disabling or removing the vulnerable Bellows Accordion Menu plugin or applying manual input sanitization if feasible. Monitor vendor channels for updates and apply patches promptly once available.
