CVSS 3.1
8.5 highCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:NCVE-2026-30242
High (8.5) in plane plane. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in plane 1.2.3.
Plane is an an open-source project management tool. Prior to version 1.2.3, the webhook URL validation in plane/app/serializers/webhook.py only checks ip.is_loopback, allowing attackers with workspace ADMIN role to create webhooks pointing to private/internal network addresses (10.x.x.x, 172.16.x.x, 192.168.x.x, 169.254.169.254, etc.). When webhook events fire, the server makes requests to these internal addresses and stores the response — enabling SSRF with full response read-back. This issue has been patched in version 1.2.3.
