Prior to 1.4.0, the fix for CVE-2026-30242 validates webhook IP addresses only when the webhook is created in apps/api/plane/app/serializers/webhook.py. The delivery task in apps/api/plane/bgtasks/webhook_task.py performs a separate DNS resolution when sending the request and does not validate the resolved IP address, allowing DNS rebinding to bypass the SSRF protection. This issue is fixed in 1.4.0.","state":0,"publishedAt":"2026-10-05T17:41:33.11+00:00","modifiedAt":"2026-10-07T20:54:46.744+00:00","affected":[{"ecosystem":"Vendor product","name":"plane","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"makeplane\",\n                    \"product\": \"plane\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.4.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:N","score":7.6,"severity":"HIGH"}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-whh3-5g95-4qhc","https://github.com/makeplane/plane/pull/9163","https://github.com/makeplane/plane/commit/04622ce1188c4680951f0001e35efb342fe51615","https://github.com/makeplane/plane/releases/tag/v1.4.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104973","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104973","identifiers":["CVE-2026-104973"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
