Prior to 1.4.0, the webhook delivery task in apps/api/plane/bgtasks/webhook_task.py calls requests.post() without allow_redirects=False and does not validate redirect targets. validate_url() blocks private, loopback, link-local, and reserved addresses in the original webhook URL, but the final URL reached after one or more redirects is not checked. A user who can create a workspace can register a webhook pointing to an attacker-controlled public endpoint that returns a 302 redirect to an internal address. The Plane worker then fetches internal resources, including cloud metadata, and stores the response body in webhook_logs, where the attacker can retrieve it through the workspace webhook-logs API. This issue is fixed in 1.4.0.","state":0,"publishedAt":"2026-10-05T18:02:53.127+00:00","modifiedAt":"2026-10-07T21:39:44.814+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:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-mq87-52pf-hm3h","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-2026-105636","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105636","identifiers":["CVE-2026-105636"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
