WooCommerce & Blocks Vulnerability | Fixed Blog

A critical vulnerability in WooCommerce and WooCommerce Blocks has been discovered. This was discovered by a security researcher and a public announcement was made this morning.

Automattic, the WooCommerce plugin developers, have announced the vulnerability and released a security patch which closes the vulnerability in all 90+ affected versions of WooCommerce. The actual details on the vulnerability are unclear at this point.

This impacts WooCommerce installations from versions 3.3 to 5.5, and versions 2.5 to 5.5 for WooCommerce Blocks. The released security patch is version 5.5.1.

It is imperative that WooCommerce installations are up to date. The WooCommerce team is also recommending that merchants update their login credentials after updating to mitigate any possible exploit vectors.
