Post Grid Gutenberg Blocks <= 5.0.32 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'searchnoresult' Block Attribute

Post Grid Gutenberg Blocks – PostX: Currently marked unpatched

Affected versions: *-5.0.32

Vulnerability type: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Affected software, patched versions and attribution

The Post Grid Gutenberg Blocks – PostX plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'searchnoresult' Block Attribute in all versions up to, and including, 5.0.32 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is particularly concerning in a cross-privilege scenario where a Contributor creates a pending or draft post containing the malicious block attribute, which then executes arbitrary JavaScript in the browser session of an Editor or Administrator who previews that post.

Post Grid Gutenberg Blocks for News, Magazines, Blog Websites <= 5.0.31 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'moreResultsText' Block Attribute

Post Grid Gutenberg Blocks – PostX: Currently marked unpatched

Affected versions: *-5.0.31

Vulnerability type: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Affected software, patched versions and attribution

The Ultimate Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'moreResultsText' block attribute of the ultimate-post/advanced-search block in versions up to and including 5.0.31. This is due to insufficient input sanitization and output escaping in the Advanced_Search::content() render callback: the attribute value is filtered with wp_kses(), which strips disallowed HTML tags but does NOT escape HTML special characters such as double quotes in plain text, and the result is then concatenated directly into the data-viewmoretext HTML attribute without esc_attr(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
