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.","state":0,"publishedAt":"2026-10-11T12:19:42.324+00:00","modifiedAt":"2026-10-13T17:00:42.169+00:00","affected":[{"ecosystem":"Vendor product","name":"speedtest-tracker","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"alexjustesen\",\n                    \"product\": \"speedtest-tracker\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"1.15.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:github/alexjustesen/speedtest-tracker\",\n                    \"repo\": \"https://github.com/alexjustesen/speedtest-tracker\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7,"severity":"LOW"}],"references":["https://hackmd.io/@haind03/speedtest-tracker-trust-proxies-allowlist-bypass","https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/bootstrap/app.php#L23-L41","https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/AllowedIpAddressesMiddleware.php#L16-L27","https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/PrometheusAllowedIpMiddleware.php#L22-L42","https://github.com/alexjustesen/speedtest-tracker","https://www.vulncheck.com/advisories/speedtest-tracker-through-1.15.0-ip-allowlist-bypass-via-x-forwarded-for-spoofing"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-108736","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-108736","identifiers":["CVE-2026-108736"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
