CVE-2026-6443

Description

The Accordion and Accordion Slider plugin for WordPress is vulnerable to an injected backdoor in version 1.4.6. This is due to the plugin being sold to a malicious threat actor that embedded a backdoor in all of the plugin's they acquired. This makes it possible for the threat actor to maintain a persistent backdoor and inject spam into the affected sites.
