CVE-2024-6158 | Category Posts Widget (Free < 4.9.17, Pro < 4.9.13) - Admin+ Stored XSS

Exp

The Category Posts Widget WordPress plugin before 4.9.17, term-and-category-based-posts-widget WordPress plugin before 4.9.13 does not validate and escape some of its "Category Posts" widget settings before outputting them back in a page/post where the Widget is embed, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
