CVE-2026-9626 (GCVE-0-2026-9626)
Vulnerability from nvd – Published: 2026-07-03 04:30 – Updated: 2026-07-03 04:30

Title
JSON API User <= 4.1.0 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'content' Parameter
Summary
The JSON API User plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content' parameter of the post_comment API endpoint in versions up to, and including, 4.1.0 This is due to insufficient input sanitization in the post_comment() function, which passes the attacker-controlled comment_content value directly to wp_insert_comment() without applying any HTML sanitization, and additionally allows the caller to set comment_approved=1 to self-approve the comment and bypass moderation. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Severity
