CVE-2026-7566 Details
Description
The LearnPress – Backup & Migration Tool plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.1.4 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
A PHP Object Injection vulnerability has been identified in the LearnPress Backup & Migration Tool plugin for WordPress, affecting all versions through 4.1.4. The vulnerability arises from the deserialization of untrusted input, allowing authenticated attackers with administrator-level access to inject PHP objects. However, this vulnerability has no impact on its own unless another plugin or theme with a suitable PHP Object Injection chain is present on the site. If such a chain exists, it could potentially enable the attacker to delete arbitrary files, access sensitive data, or execute code, depending on the specific chain involved.
Users can update the LearnPress Backup & Migration Tool plugin to version 4.1.5 or later, where this vulnerability has been addressed.
