The Speed Optimizer WordPress plugin before 7.8.5 does not verify network-level privilege before applying an option change to the whole multisite network, nor restrict which option may be changed, allowing a site administrator who is not a Super Admin to create or overwrite network-wide options.

The Speed Optimizer WordPress plugin before 7.8.5 does not sanitise or escape some of its settings before outputting them in the head of front-end pages, which could allow high-privilege users such as admins to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in a multisite setup).
Aug 18, 2026Speed Optimizer – The All-In-One Performance-Boosting: Stored Cross-Site ScriptingCVE-2026-15421 · affects up to 7.8.0 · reported by WordfenceMedium 6.4
The Speed Optimizer – The All-In-One Performance-Boosting Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Image Tag Attributes in all versions up to, and including, 7.8.0 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 only exploitable when the site administrator has enabled the Lazy Load Media option in the plugin settings.
