CVE-2026-2390

9th percentile - higher than 9% of all known CVEs

The Powerkit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Lazy Load module's image processing in all versions up to, and including, 3.0.4. This is due to the 'content_process_images' function using a flawed regex-based HTML attribute parser. 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.

The risk includes the possibility of injecting malicious scripts by content authors, which could lead to session theft, admin account takeover, or malware distribution to visitors.

It is recommended to update the Powerkit plugin to a version later than 3.0.4 that includes a fix for the HTML parser, and to restrict Contributor permissions to trusted users.
