Quick assessment

Affected
Unknown Master Slider
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

**Master Slider WordPress 插件（版本 3.11.2 及以下）在将部分短代码（shortcode）属性输出到内联脚本（inline script）上下文时，未对其进行清理和转义。这可能导致拥有“Contributor（贡献者）”及以上权限的用户发起“存储型跨站脚本攻击（Stored Cross-Site Scripting, XSS）”。当浏览受影响的帖子时，该攻击将得以执行。 目前尚无已发布的修复版本。在官方发布修复版本之前，建议将“Contributor”角色限制给受信任的用户，或直接停

Vulnerability Title
Master Slider <= 3.11.2 - Contributor+ Stored XSS via ms_slider Shortcode Attributes
Source: CVE Program / CVE List V5
Vulnerability Description
The Master Slider WordPress plugin through 3.11.2 does not sanitise and escape some of its shortcode attributes before outputting them in an inline script context, which could allow users with the Contributor role and above to perform Stored Cross-Site Scripting attacks that execute when the affected post is viewed. No fixed version is available. Until one ships, restrict the Contributor role to trusted users, or deactivate the Master Slider WordPress plugin through 3.11.2. Site owners who need to keep it active can block the ms_slider shortcode for roles below Editor, for example with a shortcode-restriction Master Slider WordPress plugin through 3.11.2, which prevents the attack without removing the Master Slider WordPress plugin through 3.11.2.
