Mint.HTTP1.decode_body/5 in lib/mint/http1.ex then discards every byte up to the CRLF with Parse.ignore_until_crlf/1, so the accepted grammar is a run of hex digits followed by arbitrary bytes, where RFC 9112 permits only a ;-introduced chunk extension. Lines such as 5ZZZZZ and 5 9 are accepted as chunk size 5, and 0ZZZZ is accepted as the terminating chunk that ends the message body. An RFC-strict intermediary rejects such a line while Mint accepts it, so the two disagree on chunk boundaries and on where the response ends.\n\nThis issue affects mint: from 0.1.0 before 1.10.1."}],"affected":[{"source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db","affectedData":[{"vendor":"elixir-mint","product":"mint","defaultStatus":"unaffected","collectionURL":"https://repo.hex.pm","packageName":"mint","cpes":["cpe:2.3:a:elixir-mint:mint:*:*:*:*:*:*:*:*"],"modules":["'Elixir.Mint.HTTP1.Parse'","'Elixir.Mint.HTTP1'"],"programFiles":["lib/mint/http1/parse.ex","lib/mint/http1.ex"],"programRoutines":[{"name":"'Elixir.Mint.HTTP1.Parse':chunk_size/1"},{"name":"'Elixir.Mint.HTTP1.Parse':ignore_until_crlf/1"},{"name":"'Elixir.Mint.HTTP1':decode_body/5"}],"repo":"https://github.com/elixir-mint/mint","packageURL":"pkg:hex/mint","versions":[{"version":"0.1.0","lessThan":"1.10.1","versionType":"semver","status":"affected"}]},{"vendor":"elixir-mint","product":"mint","defaultStatus":"unaffected","collectionURL":"https://github.com","packageName":"elixir-mint/mint","cpes":["cpe:2.3:a:elixir-mint:mint:*:*:*:*:*:*:*:*"],"modules":["'Elixir.Mint.HTTP1.Parse'","'Elixir.Mint.HTTP1'"],"programFiles":["lib/mint/http1/parse.ex","lib/mint/http1.ex"],"programRoutines":[{"name":"'Elixir.Mint.HTTP1.Parse':chunk_size/1"},{"name":"'Elixir.Mint.HTTP1.Parse':ignore_until_crlf/1"},{"name":"'Elixir.Mint.HTTP1':decode_body/5"}],"repo":"https://github.com/elixir-mint/mint","packageURL":"pkg:github/elixir-mint/mint","versions":[{"version":"60089586ec7adc9fddb09f69a2f5919ba9ac7f33","lessThan":"c82377838dc6e275ef40bafa664fbcdf50270c60","versionType":"git","status":"affected"}]}]}],"metrics":{"cvssMetricV40":[{"source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db","type":"Secondary","cvssData":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":6.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"PRESENT","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"LOW","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-21T18:29:40.588404Z","id":"CVE-2026-82672","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db","type":"Secondary","description":[{"lang":"en","value":"CWE-444"}]}],"references":[{"url":"https://cna.erlef.org/cves/CVE-2026-82672.html","source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db"},{"url":"https://github.com/elixir-mint/mint/commit/60089586ec7adc9fddb09f69a2f5919ba9ac7f33","source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db"},{"url":"https://github.com/elixir-mint/mint/commit/c82377838dc6e275ef40bafa664fbcdf50270c60","source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db"},{"url":"https://github.com/elixir-mint/mint/security/advisories/GHSA-rj5m-69wp-cxq9","source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db"},{"url":"https://osv.dev/vulnerability/EEF-CVE-2026-82672","source":"6b3ad84c-e1a6-4bf7-a703-f496b71e49db"},{"url":"https://github.com/elixir-mint/mint/security/advisories/GHSA-rj5m-69wp-cxq9","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}}]}
