Because the handler performs no map-lookup validity check and receives on a nil channel that blocks forever, with no timeout, no context cancellation, and no server-side reclamation due to absent HTTP server timeouts, each malicious request permanently holds one goroutine, one file descriptor, and approximately 50 kB of memory until the server's file descriptor limit is reached and listener Accept calls fail, halting all tunnel traffic forwarding for all users."}], "tags": ["x_open-source"], "datePublic": "2026-08-01T00:00:00.000Z", "problemTypes": [{"descriptions": [{"lang": "en", "cweId": "CWE-833", "description": "Deadlock", "type": "CWE"}]}], "affected": [{"defaultStatus": "affected", "vendor": "boringproxy", "product": "boringproxy", "packageURL": "pkg:github/boringproxy/boringproxy", "repo": "https://github.com/boringproxy/boringproxy", "versions": [{"status": "affected", "version": "0", "versionType": "semver", "lessThanOrEqual": "0.10.0"}]}], "metrics": [{"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV4_0": {"attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "LOW", "userInteraction": "NONE", "vulnConfidentialityImpact": "NONE", "subConfidentialityImpact": "NONE", "vulnIntegrityImpact": "NONE", "subIntegrityImpact": "NONE", "vulnAvailabilityImpact": "HIGH", "subAvailabilityImpact": "NONE", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "HIGH", "baseScore": 7.1, "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}}, {"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV3_1": {"attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH", "version": "3.1", "baseSeverity": "MEDIUM", "baseScore": 6.5, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}}], "references": [{"url": "https://github.com/theopaid/Denial-Of-Service-Through-Unbounded-Resource-Consumption-In-Request-Handler-boringproxy-/blob/master/README.md", "name": "Researcher Disclosure", "tags": ["technical-description", "exploit"]}, {"url": "https://www.vulncheck.com/advisories/boringproxy-resource-exhaustion-dos-via-get-loading-endpoint", "tags": ["third-party-advisory"]}], "credits": [{"lang": "en", "value": "Theodosis Paidakis", "type": "finder"}], "source": {"discovery": "UNKNOWN"}, "x_generator": {"engine": "vulncheck"}}}}
