CVE-2026-121970 (GCVE-0-2026-121970)

Vulnerability from cvelistv5 – Published: 2026-11-04 13:01 – Updated: 2026-11-04 18:47 X_Open Source

Title

Pay with Vipps and MobilePay for WooCommerce before 6.4.1 Webhook Signature Forgery

Summary

Pay with Vipps and MobilePay for WooCommerce (woo-vipps) before 6.4.1 contains an improper cryptographic signature verification vulnerability in the recurring-payment webhook handler that allows unauthenticated attackers to forge webhook requests when no local webhook secret is stored, because the code fails to return on an empty secret and computes an HMAC keyed with an empty string using a loose == comparison instead of hash_equals. Attackers can craft a recurring.agreement-stopped.v1 event with a known agreementId and a matching empty-key signature to cancel a victim's active WooCommerce subscription.

CVE-2024-11786 (GCVE-0-2024-11786)

Vulnerability from cvelistv5 – Published: 2024-11-28 08:47 – Updated: 2026-04-08 17:24

Title

Login with Vipps and MobilePay <= 1.3.3 - Authenticated (Contributor+) Stored Cross-Site Scripting

Summary

The Login with Vipps and MobilePay plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'continue-with-vipps' shortcode in all versions up to, and including, 1.3.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Severity

6.4 (Medium)
