CVE-2026-11784 Medium · 4.3 CWE-352 Jun 18, 2026

Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization <= 4.2.6 - Cross-Site Request Forgery via 'optml_replace_file' AJAX Action

The Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.2.6. This is due to missing or incorrect nonce validation on the replace_file function. This makes it possible for unauthenticated attackers to overwrite existing media attachments with attacker-supplied file content by supplying a forged multipart POST request targeting any attachment the victim has edit_post capability over via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. The forged request requires a victim with at least Author-level privileges, as the handler enforces a current_user_can('edit_post', $id) check; tricking an Author-level or higher user into clicking a crafted link is sufficient to trigger the overwrite against attachments that user can edit.

CVE-2026-5226 Medium · 6.1 CWE-79 Apr 10, 2026

Optimole <= 4.2.3 - Reflected Cross-Site Scripting via Page Profiler URL

The Optimole – Optimize Images in Real Time plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL paths in versions up to, and including, 4.2.3 This is due to insufficient output escaping on user-supplied URL paths in the get_current_url() function, which are inserted into JavaScript code via str_replace() without proper JavaScript context escaping in the replace_content() function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

CVE-2026-5217 High · 7.2 CWE-79 Apr 10, 2026

Optimole <= 4.2.2 - Unauthenticated Stored Cross-Site Scripting via Srcset Descriptor Parameter

The Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 4.2.2. This is due to insufficient input sanitization and output escaping on the user-supplied 's' parameter (srcset descriptor) in the unauthenticated /wp-json/optimole/v1/optimizations REST endpoint. The endpoint validates requests using an HMAC signature and timestamp, but these values are exposed directly in the frontend HTML making them accessible to any visitor. The plugin uses sanitize_text_field() on the descriptor value of rest.php, which strips HTML tags but does not escape double quotes. The poisoned descriptor is then stored via transients (backed by the WordPress options table) and later retrieved and injected verbatim into the srcset attribute of tag_replacer.php without proper escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts into pages that will execute whenever a user accesses the injected page.

CVE-2026-1843 High · 7.2 CWE-79 Feb 14, 2026

Super Page Cache <= 5.2.2 - Unauthenticated Stored Cross-Site Scripting via Activity Log

The Super Page Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Activity Log in all versions up to, and including, 5.2.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Image optimization service by Optimole <= 4.1.0 - Insecure Direct Object Reference to Authenticated (Author+) Media Offload

The Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.0 via the /wp-json/optml/v1/move_image REST API endpoint due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Author-level access and above, to offload media that doesn't belong to them.
