CVE-2025-3810 (GCVE-0-2025-3810)

Vulnerability from cvelistv5 – Published: 2025-05-09 01:42 – Updated: 2026-04-08 16:53

Title
WPBookit <= 1.0.2 - Insecure Direct Object Reference to Unauthenticated Privilege Escalation via Account Takeover
Summary
The WPBookit plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.0.2. This is due to the plugin not properly validating a user's identity prior to updating their details like password and email through the edit_profile_data() function. This makes it possible for unauthenticated attackers to change arbitrary user's email addresses and passwords, including administrators, and leverage that to gain access to their account.

CVE-2025-3889 (GCVE-0-2025-3889)

Vulnerability from cvelistv5 – Published: 2025-05-01 11:11 – Updated: 2026-04-08 16:48

Title
WordPress Simple PayPal Shopping Cart <= 5.1.3 - Insecure Direct Object Reference via 'quantity'
Summary
The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.3 via the 'process_payment_data' due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to change the quantity of a product to a negative number, which subtracts the product cost from the total order cost. The attack will only work with Manual Checkout mode, as PayPal and Stripe will not process payments for a negative quantity.

Description:

  • Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation

Phase: Architecture and Design

Description:

  • Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
