The WordPress WooCommerce Payments plugin has recently been targeted by hackers who are exploiting a critical vulnerability in the software. This vulnerability, which affects versions 4.8.0 and higher, allows hackers to gain unauthorized privileges, including administrative access.
Given that the plugin has over 600,000 active installations, this bug presents a significant security risk. Automattic, the company responsible for WooCommerce, has taken steps to address the issue by force-installing a security fix on vulnerable WordPress installations. However, there are concerns among researchers that future exploitation may still occur due to the severity of the bug.
The exploit involves the addition of a specific request header, enabling attackers to impersonate a specified user ID. A proof-of-concept exploit has already been discovered, which creates a new admin user on vulnerable sites. Reports indicate that a large-scale campaign is underway, targeting over 157,000 sites, with attacks peaking at 1.3 million against these sites on July 16, 2023.
In light of these developments, site administrators are strongly advised to update their WooCommerce Payment plugin installations and conduct thorough scans for any unusual PHP files or suspicious admin accounts.
