title: Potential XSRF Token Leakage via Axios Misconfiguration — CVE-2026-42042
id: scw-2026-04-24-ai-1
status: experimental
level: medium
description: |
  This rule detects potential exploitation of CVE-2026-42042. The vulnerability occurs when the Axios library's XSRF token protection is bypassed due to non-strict boolean comparison for the 'withXSRFToken' configuration property. This can lead to XSRF tokens being sent to unintended cross-origin servers. This detection looks for the presence of 'withXSRFToken' in the URI query, which is a strong indicator of the vulnerable configuration being triggered.
