CVE-2024-6158: Tiptoppress Term And Category Based Posts Widget

Medium severity, CVSS 4.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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)

Affected products

• Tiptoppress Term And Category Based Posts Widget: before 4.9.13 (fixed in 4.9.13)
• Zephyrwest Category Posts Widget: before 4.9.17 (fixed in 4.9.17)
