Research Description
Speed Optimizer &#8211; The All-In-One Performance-Boosting Plugin [sg-cachepress] < 5.0.13 SiteGround Optimizer <= 5.0.12 - Missing Authorization The SiteGround Optimizer plugin for WordPress is vulnerable to authorization bypass leading to Remote Code Execution and Local File Inclusion in versions up to, and including, 5.0.12 due to incorrect use of an access control attribute on the switch_php function called via the /switch-php REST API route. This allows attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
Affected versions
max 5.0.13.

Date
Mar 30, 2026
Research Description
Performance and caching plugins are security-relevant because they introduce high-impact configuration inside wp-admin and can directly affect availability and content delivery behavior. If access control, request integrity, or output handling is weak, attackers may force cache purges or mode changes via CSRF, expose sensitive diagnostics, or manipulate settings that change how pages and assets are cached and served. Speed Optimizer – The All-In-One Performance-Boosting Plugin version 7.7.7 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64641, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for performance management and caching tooling.
Affected versions
Min 7.8.2, max 7.8.2.

Research Description
The Autoptimize WordPress plugin before 3.1.15, Clearfy Cache WordPress plugin before 2.4.2, Speed Optimizer WordPress plugin before 7.7.9 are vulnerable to unauthenticated Stored Cross-Site Scripting (XSS) due to a predictable replacement hash used during the HTML minification process and abusing a regular expression.
