50K WordPress sites exposed to RCE attacks by critical bug in backup plugin

A critical severity vulnerability in a WordPress plugin with more than 90,000 installs can let attackers gain remote code execution to fully compromise vulnerable websites.

The security bug was discovered by a team of bug hunters known as Nex Team, who reported it to WordPress security firm Wordfence under a recently launched bug bounty program.

It impacts all plugin versions up to and including Backup Migration 1.3.6, and malicious actors can exploit it in low-complexity attacks without user interaction.

Despite the release of the patched Backup Migration 1.3.8 plugin version on the day of the report, almost 50,000 WordPress websites using a vulnerable version still have to be secured nearly one week later, as WordPress.org org download stats show.

WordPress administrators are also being targeted by a phishing campaign attempting to trick them into installing malicious plugins using fake WordPress security advisories for a fictitious vulnerability tracked as CVE-2023-45124 as bait.
