# Drupal Commerce Stripe: webhook signatures can be spoofed, versions 1.4 and 2.2.3 affected

Drupal Commerce Stripe does not properly verify Stripe's cryptographic signature on incoming requests. An attacker can forge a signature and send fake Stripe events to the site.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version of `drupal/stripe` (or the Commerce Stripe module) with `composer show drupal/stripe` and compare against the affected ranges.
- Look for the Stripe webhook endpoint in the site configuration and confirm whether it is reachable from the internet.

## Fix

- Commerce Stripe versions from 0.0.0 to 1.4 and from 2.0.0 to 2.2.3 are affected; the sources do not state a fixed version.

## Timeline

- 2026-10-30T04:28:39+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118559

## From the sources

Improper Verification of Cryptographic Signature vulnerability in Drupal Commerce Stripe allows Signature Spoof. This issue affects Commerce Stripe versions: from 0.0.0 to 1.4, from 2.0.0 to 2.2.3.
