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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","score":8.5},"cwes":["CWE-918"],"references":["https://github.com/makeplane/plane/releases/tag/v1.2.3","https://github.com/makeplane/plane/security/advisories/GHSA-fpx8-73gf-7x73"],"products":["plane:plane"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-30242","score":0.0035,"percentile":0.28708,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-fpx8-73gf-7x73","url":"https://osv.dev/vulnerability/GHSA-fpx8-73gf-7x73","summary":"Plane has SSRF via Incomplete IP Validation in Webhook URL Serializer","modified":"2026-03-09T13:16:29.177805Z","packages":[{"ecosystem":"PyPI","name":"plane","purl":"pkg:pypi/plane","ranges":["<1.2.3"],"fixed":["1.2.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
