{"id":"CVE-2026-108736","summary":"Speedtest Tracker through 1.15.0 IP Allowlist Bypass via X-Forwarded-For Spoofing","details":"Speedtest Tracker through 1.15.0 contains an IP allowlist bypass vulnerability that allows unauthenticated remote attackers to evade ALLOWED_IPS and Prometheus allowlists by spoofing X-Forwarded-For headers. 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.","modified":"2026-10-15T02:31:09.763987698Z","published":"2026-10-11T12:19:42.324Z","database_specific":{"cwe_ids":["CWE-348"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108736.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108736.json"},{"type":"ADVISORY","url":"https://hackmd.io/@haind03/speedtest-tracker-trust-proxies-allowlist-bypass"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-108736"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/speedtest-tracker-through-1.15.0-ip-allowlist-bypass-via-x-forwarded-for-spoofing"},{"type":"PACKAGE","url":"https://github.com/alexjustesen/speedtest-tracker"},{"type":"ARTICLE","url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/AllowedIpAddressesMiddleware.php#L16-L27"},{"type":"ARTICLE","url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/app/Http/Middleware/PrometheusAllowedIpMiddleware.php#L22-L42"},{"type":"ARTICLE","url":"https://github.com/alexjustesen/speedtest-tracker/blob/fce6eb36181ed70b5b0763c391a50b806d7e3da7/bootstrap/app.php#L23-L41"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/alexjustesen/speedtest-tracker","events":[{"introduced":"0"},{"fixed":"fce6eb36181ed70b5b0763c391a50b806d7e3da7"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.15.0"},{"fixed":"1.15.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v1.14.8","v1.14.7","v1.14.6","v1.14.5","v1.14.4","v1.14.3","v1.14.0","v1.14.2","v1.14.1","v1.13.12","v1.13.11","v1.13.10","v1.13.7","v1.13.9","v1.13.8","v1.13.6","v1.13.5","v1.13.4","v1.13.3","v1.13.2","v1.13.1","v1.13.0","v1.12.4","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.11.2","v1.11.1","v1.11.0","v1.10.4-beta.6","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.0","v1.8.0","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.11","v1.6.10","v1.6.9","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.0","v1.4.2","v1.4.1","v1.4.0","v1.3.0","v1.2.5","v1.2.4","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.26.0","v0.25.1","v0.25.0","v0.24.3","v0.24.2","v0.24.1","v0.24.0","v0.23.1","v0.23.0","v0.22.0","v0.21.6","v0.21.5","v0.21.4","v0.21.3","v0.21.2","v0.21.1","v0.21.0","v0.20.9","v0.20.8","v0.20.7","v0.20.6","v0.20.5","v0.20.4","v0.20.3","v0.20.2","v0.20.1","v0.20.0","v0.19.0","v0.18.7","v0.18.6","v0.18.5","v0.18.4","v0.18.3","v0.18.2","v0.18.1","v0.18.0","v0.17.3","v0.17.2","v0.17.1","v0.17.0","v0.16.6","v0.16.5","v0.16.4","v0.16.3","v0.16.2","v0.16.1","v0.16.0","v0.15.5","v0.15.4","v0.15.3","v0.15.2","v0.15.1","v0.15.0","v0.14.7","v0.14.6","v0.14.5","v0.14.4","v0.14.3","v0.14.2","v0.14.2-beta4","v0.14.2-beta3","v0.14.2-beta2","v0.14.2-beta1","v0.14.1","v0.14.0","v0.14.0-beta8","v0.14.0-beta7","v0.14.0-beta6","v0.14.0-beta5","v0.14.0-beta4","v0.14.0-beta3","v0.14.0-beta2","v0.14.0-beta1","v0.13.4","v0.13.3","v0.13.2","v0.13.1","v0.13.0","v0.13.0-beta.3","v0.13.0-beta.2","v0.13.0-beta.1","v0.12.2","v0.12.1","v0.12.0","v0.12.0-beta.6","v0.12.0-beta.5","v0.12.0-beta.4","v0.12.0-beta.3","v0.12.0-beta.2","v0.12.0-beta.1","v0.11.22","v0.11.21","v0.11.20","v0.11.19","v0.11.18","v0.11.17","v0.11.16","v0.11.15","v0.11.14","v0.11.13","v0.11.12","v0.11.11","v0.11.10","v0.11.9","v0.11.8","v0.11.7","v0.11.6","v0.11.5","v0.11.4","v0.11.3","v0.11.2","v0.11.1","v0.11.0","v0.10.0","v0.9.2","v0.9.1","v0.9.0","v0.8.1","v0.8.0","v0.7.1","v0.7.0","v0.6.2","v0.6.1","v0.6.0","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.1","v0.2.0","v0.1.2","v0.1.1","v0.1.0","v.0.1.0-beta","v0.1.0-alpha.10","v0.1.0-alpha.9","v0.1.0-alpha.8","v0.1.0-alpha7","v0.1.0-alpha.6","v0.1.0-alpha.5","v0.1.0-alpha.4","v0.1.0-alpha.3","v0.1.0-alpha.2","v0.1.0-alpha.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-108736.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
