{"schema":"threatline.record/2","record":{"id":"CVE-2026-55177","aliases":["GHSA-r95q-fp26-h3hc"],"summary":"CloudTAK: Authenticated full-read SSRF in /api/esri* routes — user-controlled URL fetched with no IP-classification guard","details":"CloudTAK is a browser-based Common Operating Picture and situational awareness tool compatible with TAK. Prior to version 13.10.0, every route in the ESRI helper family (api/routes/esri.ts) takes a fully attacker-controlled URL from the request (POST /api/esri body url, and the portal / server / layer query parameters on the GET /api/esri/* routes) and passes it into EsriBase / EsriProxyPortal / EsriProxyServer / EsriProxyLayer in api/lib/esri.ts, which fetch it with the bare fetch from @tak-ps/etl. No IP / DNS / hostname classification is applied at any point, so the destination is never validated against private, loopback, or link-local ranges. Any authenticated user (the routes only require Auth.is_auth(config, req, { anyResources: true }), i.e. any token, not an admin) can therefore make the CloudTAK server issue arbitrary outbound GET/POST requests to internal addresses such as the cloud instance-metadata service (169.254.169.254), loopback admin ports (127.0.0.1:<port>), and other hosts reachable only from inside the deployment VPC. This is a full-read SSRF, not blind: on success the upstream JSON body is returned to the caller via res.json(...), and on failure the upstream error string is reflected verbatim as ESRI Server Error: <message>. An attacker can read cloud metadata (and the temporary IAM credentials the instance role exposes), enumerate internal services, and exfiltrate their response bodies. The sniff() URL classifier provides no protection: it only pattern-matches the pathname (/rest, /arcgis/rest, /sharing/rest), so a URL like http://169.254.169.254/arcgis/rest or http://127.0.0.1:8500/rest passes sniff() and is fetched. This issue has been patched in version 13.10.0.","categories":["Libraries & packages"],"product":"CloudTAK","vendor":"dfpc-coe","ecosystem":"npm","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55177","source_modified_at":"2026-09-30T19:34:04.594Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"CloudTAK","vendor":"dfpc-coe","versions":[{"version":"< 13.10.0","status":"affected"}],"defaultStatus":null},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-r95q-fp26-h3hc","source_modified_at":"2026-07-17T21:56:43.644423Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"@tak-ps/cloudtak","ecosystem":"npm","purl":"pkg:npm/%40tak-ps/cloudtak"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"13.10.0"}]}],"versions":[]}],"fixed_versions":[{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-r95q-fp26-h3hc","source_modified_at":"2026-07-17T21:56:43.644423Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"@tak-ps/cloudtak","ecosystem":"npm","purl":"pkg:npm/%40tak-ps/cloudtak"},"version":"13.10.0"}],"cvss":7.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0038,"percentile":0.30785,"score_date":"2026-10-23"},"published_at":"2026-09-30T16:25:02.258Z","modified_at":"2026-09-30T19:34:04.594Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55177","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T19:34:04.594Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-r95q-fp26-h3hc","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-07-17T21:56:43.644423Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55177","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/dfpc-coe/CloudTAK/security/advisories/GHSA-r95q-fp26-h3hc","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/dfpc-coe/CloudTAK/releases/tag/v13.10.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-09-30T19:32:16.314025Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-30T19:34:04.594Z","content_hash":"ab280f3b13c1d44d2a9db0688526f950c5289191880cef4f6c6d752dae9ab842"}}
