Quick assessment

Affected
Unknown King Addons for Elementor
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.

Elementor 的 King Addons WordPress 插件在 51.1.81 版本之前，未对一组图像优化操作执行基于对象（per-object）的授权检查。这些操作仅依赖于一个粗粒度的能力（capability）进行控制，而低权限用户也持有该能力，且系统从未确认操作者是否为目标对象的所有者。这使得拥有作者（author）及以上权限的已认证用户能够： 1. 泄露其他用户（包括管理员）的媒体文件的绝对文件路径； 2. 覆盖这些媒体文件的字节内容； 3. 在站点范围内重新引用（re-reference）属于

King Addons for Elementor 51.1.56 - 51.1.80 - Author+ Missing Authorization via Image Optimizer

Vulnerability Description
The King Addons for Elementor WordPress plugin before 51.1.81 does not perform per-object authorization checks on a group of image-optimization actions, gating them only on a coarse capability that lower-privileged users also hold and never confirming ownership of the targeted object, allowing authenticated users with author-level access and above to disclose absolute file paths for, overwrite the bytes of, and site-wide re-reference media belonging to other users, including administrators.
