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.","categories":["Libraries & packages"],"product":"plane","vendor":"makeplane","ecosystem":"npm","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104973","source_modified_at":"2026-10-07T20:54:46.744Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"plane","vendor":"makeplane","versions":[{"status":"affected","version":"< 1.4.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-whh3-5g95-4qhc","source_modified_at":"2026-10-05T17:40:52Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"other","name":"makeplane/plane"},"range":"<= 1.3.1"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-j5f4-cc29-5x44","source_modified_at":"2026-10-08T10:56:40.691028011Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"adm-zip","purl":"pkg:npm/adm-zip"},"ranges":[{"events":[{"introduced":"0"},{"fixed":"0.6.1"}],"type":"SEMVER"}],"versions":[]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-whh3-5g95-4qhc","source_modified_at":"2026-10-05T17:40:52Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-j5f4-cc29-5x44","source_modified_at":"2026-10-08T10:56:40.691028011Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"adm-zip","purl":"pkg:npm/adm-zip"},"version":"0.6.1"}],"cvss":7.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00268,"percentile":0.17927,"score_date":"2026-10-23"},"published_at":"2026-10-05T17:41:33.110Z","modified_at":"2026-10-08T10:56:40.691028011Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104973","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T20:54:46.744Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-whh3-5g95-4qhc","fetched_at":"2026-10-24T00:31:04.721601Z","source_modified_at":"2026-10-05T17:40:52Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-j5f4-cc29-5x44","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-08T10:56:40.691028011Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104973","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/makeplane/plane/security/advisories/GHSA-whh3-5g95-4qhc","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9163","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/04622ce1188c4680951f0001e35efb342fe51615","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","tags":["exploit"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-07T20:54:23.222680Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-08T10:56:40.691028011Z","content_hash":"312ed40270ab23a202d53ba25a5e8d2973e01b9ace3a58c6bc4433851ab07bba"}}
