CVE-2026-9620

WP Latest Posts <= 5.0.11 - Authenticated (Author+) Stored Cross-Site Scripting via Post Content Image src Attribute

The WP Latest Posts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via crafted image src attributes in post content in versions up to, and including, 5.0.11. This is due to insufficient output escaping in the field() and loop() functions, which extract the raw src attribute value from <img> tags within post_content using a regular expression and then reconstruct new <img> elements or CSS background-image declarations by directly concatenating the unescaped value — bypassing WordPress's kses filtering entirely. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
