Contributor-level code execution via shortcode callback
Published Apr 3, 2024 · Updated Apr 28, 2026
Code injection in Inpersttion Slivery Extender 1.0.2 and earlier allows remote authenticated users to execute server-side code. The slider_theme_section shortcode handler passes an attacker-controlled attribute to call_user_func as a callable without restricting permitted callbacks. Contributor-level WordPress access is required, and successful exploitation executes code in the server context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=1.0.2
- Affected versionversion=0 <=1.0.2 changes=[{"at":"1.0.3","status":"unaffected"}]
