What is CVE-2026-87968?
The WooCommerce Merchant plugin, utilized for managing product feeds for Google Shopping and Microsoft Advertising, is affected by a vulnerability due to insufficient security checks. Specifically, the plugin lacks appropriate nonce or capability verification on the AJAX action responsible for store registration with feed services. This oversight allows any unauthenticated visitor to exploit the vulnerability, re-register the store, and overwrite its stored shop secret, compromising the integrity of the product feeds.
Affected Version(s)
Product Feed for Google Shopping, Microsoft Advertising and 40+ Channels for WooCommerce Merchant 0 < 5.3.2
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
