Summary
The WP Latest Posts plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) 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.
Risk Assessment
Authenticated attackers with author-level access and above can inject arbitrary web scripts that will execute whenever a user accesses an injected page. This poses a serious threat to user data security.
Recommendation
It is recommended to update the WP Latest Posts plugin to the latest version to mitigate this vulnerability. Additionally, conducting an audit of post content to detect potential script injections is advisable.
Original NVD description (English source)
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.
