Why it matters

This matters because the affected product may be exposed on public websites. A vulnerable plugin can create a direct path to site compromise, malicious code deployment, or data theft.

Recommended admin actions

• Prioritize validation immediately due to critical CVSS severity.
• Identify if the Abandoned Cart Pro for WooCommerce plugin (versions 0 through 10.8.0) is installed.
• As no patch is available, immediately disable or remove the affected plugin.
• Treat internet-facing WordPress installations with this plugin as high priority for action.
• Review WordPress and web server logs for suspicious activity, especially administrator account takeovers.

Technical summary

The Abandoned Cart Pro for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass via Malleable Encryption and Bypassable HMAC in all versions up to, and including, 10.8.0. This is due to the use of MAC-free AES-CTR encryption for cart-recovery link tokens — where the 8-byte CTR nonce is carried inside the ciphertext blob and the encryption key is looked up using the attacker-supplied `user_email` GET parameter — combined with an HMAC nonce check in `wcap_email_track_links()` that is only enforced when the `wcap_nonce` parameter is non-empty, allowing complete bypass by omission, and an insecure direct object reference on the decrypted `abandoned_id` with no ownership verification confirming the cart belongs to the email used for decryption. This makes it possible for unauthenticated attackers who possess a single legitimate cart-recovery link (obtained from their own reminder email) to recover the keystream, forge a ciphertext that decrypts to any victim's cart ID, and trigger a call to `wp_set_auth_cookie()` for the victim user — achieving full account takeover of any user who has ever abandoned a cart, including administrators. The auto-login feature defaults to enabled and is forced on during plugin upgrades, meaning all affected installations are exploitable without any additional configuration.
