This vulnerability in merzedes Custom Style (<= 1.0) is a Cross-Site Request Forgery (CSRF) issue that enables stored Cross-Site Scripting (XSS). An attacker can exploit this by inducing a victim to perform unintended actions that store malicious scripts within the application, potentially leading to session hijacking, data manipulation, or other client-side attacks. The CVSS 3.1 vector indicates the attack can be performed remotely over the network with low attack complexity and no privileges required, but user interaction is necessary. The vulnerability affects confidentiality, integrity, and availability to a limited extent.

Successful exploitation can result in stored XSS, allowing attackers to execute arbitrary scripts in the context of affected users, potentially leading to session theft, unauthorized actions, or data exposure. The CSRF aspect means attackers can coerce users into submitting malicious requests without their consent. The overall impact is rated high due to the combination of these factors, affecting confidentiality, integrity, and availability.

No official patch or remediation guidance is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, users should consider implementing CSRF protections such as anti-CSRF tokens and input validation to mitigate stored XSS risks. Monitoring vendor channels for updates is recommended.
