Because bootstrap/app.php trusts every peer as a proxy, attackers can supply an allowlisted address to read /prometheus metrics and reach protected web and API endpoints.","categories":["Unclassified"],"product":"speedtest-tracker","vendor":"alexjustesen","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-108736","source_modified_at":"2026-10-13T17:00:42.169Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"speedtest-tracker","vendor":"alexjustesen","versions":[{"version":"0","lessThanOrEqual":"1.15.0","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00206,"percentile":0.10063,"score_date":"2026-10-23"},"published_at":"2026-10-11T12:19:42.324Z","modified_at":"2026-10-13T17:00:42.169Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-108736","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T17:00:42.169Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-108736","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://hackmd.io/@haind03/speedtest-tracker-trust-proxies-allowlist-bypass","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/bootstrap/app.php#L23-L41","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/AllowedIpAddressesMiddleware.php#L16-L27","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/PrometheusAllowedIpMiddleware.php#L22-L42","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/alexjustesen/speedtest-tracker","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/speedtest-tracker-through-1.15.0-ip-allowlist-bypass-via-x-forwarded-for-spoofing","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-13T15:49:35.704106Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T17:00:42.169Z","content_hash":"9e75935194fa8022cc48e86be4e3f597c5f2d8d3501b7d13a4427ab4b27eb117"}}
