A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Muneeb Layer Slider WordPress plugin versions 1.1.9.7 and below. The vulnerability was identified on January 18, 2023, and publicly disclosed on June 28, 2023. This security issue affects users with contributor-level privileges and above (Patchstack).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) with a CVSS v3.1 base score of 5.4 (MEDIUM) according to NIST, and 6.5 (MEDIUM) according to Patchstack.

The vulnerability could allow malicious actors to inject malicious scripts, including redirects, advertisements, and other HTML payloads into the website. These injected scripts would be executed when visitors access the affected site (Patchstack).

Currently, there is no official fix available for this vulnerability. However, Patchstack has issued a virtual patch to mitigate the issue by blocking potential attacks until an official fix becomes available (Patchstack).
