What is CVE-2025-11988?

The Crypto plugin for WordPress exposes a critical flaw that allows unauthorized attackers to manipulate data. An unauthenticated AJAX action can be exploited to invoke the crypto_delete_json method, leveraging a publicly-accessible nonce check. This enables deletion of JSON files named *_pending.json located in the wp-content/uploads/yak/ directory. Consequently, this vulnerability may lead to data loss and disrupt plugin functionalities that depend on these files.
