GHSA-2xcx-75h9-vr9h (CVE-2026-25631)

Details

Impact

A vulnerability in the HTTP Request node's credential domain validation allowed an authenticated attacker to send requests with credentials to unintended domains, potentially leading to credential exfiltration.

This only might affect user who have credentials that use wildcard domain patterns (e.g., *.example.com) in the "Allowed domains" setting.

Patches

This issue is fixed in version 1.121.0 and later. All users are strongly encouraged to upgrade.

Workarounds

Until projects can upgrade:

Replace wildcard domain patterns with explicit domain listings in HTTP Request credentials
Review and restrict workflow creation/modification permissions to trusted users only
Audit existing workflows using HTTP Request nodes with domain-restricted credentials
