In versions through 2.8.6, cloudflare/cors-proxy-worker.js performs a DNS-over-HTTPS safety check in hostnameResolvesToPrivate(), as used by isValidCertificateUrl() and isValidTsaUrl(), separately from the outbound fetch(targetUrl, ...). In deployments where PROXY_SECRET validation is not enabled, a direct client that controls authoritative DNS can forge the Origin header, supply a certificate, OCSP, CRL, or TSA URL that passes the proxy's accepted path checks, return a public address during validation, and return a private or link-local address during the later fetch. The endpoint can return allowed response bodies to the attacker, but exploitation requires precise timing, redirects and IP-literal obfuscation are blocked, and network reachability limits the target. This vulnerability is fixed in 2.8.7.","state":0,"publishedAt":"2026-10-14T19:00:13.518+00:00","modifiedAt":"2026-10-15T16:19:56.322+00:00","affected":[{"ecosystem":"Vendor product","name":"bentopdf","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"alam00000\",\n                    \"product\": \"bentopdf\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.8.7\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/alam00000/bentopdf/security/advisories/GHSA-wh78-rcw2-hhg9","https://github.com/alam00000/bentopdf/commit/45496fcd2ed6e02dcdde0d3839cc5024c091760c","https://github.com/alam00000/bentopdf/commit/58cd1a8893bfe06e4a59a72adc2e7db00a8b9266","https://github.com/alam00000/bentopdf/releases/tag/v2.8.7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102354","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102354","identifiers":["CVE-2026-102354"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
