    Plane has SSRF via Incomplete IP Validation in Webhook URL Serializer

    CVE-2026-30242 · GHSA-fpx8-73gf-7x73

    Affected
    • PyPI plane <= 1.2.1
    Fixed in
    1.2.3· Vendor fix available
    Issue
    The webhook URL validation in plane/app/serializers/webhook.py only checks ip.isloopback, 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. Impact - Cloud metadata exfiltration: Access AWS/GCP/Azure instance metadata (IAM credentials, tokens) - Internal service scanning: Probe internal network services not exposed to the internet - Data exfiltration via response logs: Full response body from internal services is stored and returned to the attacker through the webhook logs API - Bypass vectors: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 169.254.0.0/16, 0.0.0.0, ::ffff: mapped addresses

    Recommended action: Upgrade to 1.2.3 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
