What is CVE-2026-8848?

The Popup Maker plugin for WordPress contains a significant vulnerability allowing authenticated attackers with editor-level access to execute arbitrary plugins from malicious URLs. This occurs due to insufficient verification of user authorization, enabling exploitation that can lead to remote code execution. Critical conditions for exploitation include the need for an active Popup Maker Pro license and the absence of the Popup Maker Pro installation, which facilitates access to the legacy endpoint necessary for validation checks.

Affected Version(s)
