{“lastseen”:””,”description”:”Improper Neutralization of CRLF Sequences (‘CRLF Injection’) vulnerability in elixir-mint Mint allows HTTP Request Splitting and HTTP Request Smuggling.\\n\\nIn lib\/mint\/http1\/request.ex, the encode_request_line\/2 function splices the caller-supplied method and target arguments directly into the HTTP\/1 request line without any character validation: [method, ?\\\\s, target, \\” HTTP\/1.1\\\\r\\\\n\\”]. An application that forwards attacker-controlled input as the HTTP method or target to Mint.HTTP.request\/5 is therefore exposed to request-line CRLF injection: the attacker can terminate the request line early, inject arbitrary headers, and smuggle an entirely separate pipelined HTTP request onto the same TCP connection.\\n\\nMint 1.7.0 introduced validate_request_target\/2, which rejects CRLF and other control characters in the target by default and closes the path\/query vector unless the caller opts out via skip_target_validation: true. The method field remains unvalidated, so the method-based injection is exploitable under the default Mint configuration on all versions.\\n\\nThis issue affects mint: from 0.1.0 before 1.9.0.”,”published”:”2026-06-02T14:15:09.015Z”,”modified”:”2026-06-02T14:15:09.015Z”,”type”:”cve”,”title”:”CRLF injection in HTTP\/1 request line via unvalidated method in Mint”,”source”:”EEF”,”references”:”https:\/\/github.com\/elixir-mint\/mint\/security\/advisories\/GHSA-2pg6-44cx-c49v\\nhttps:\/\/cna.erlef.org\/cves\/CVE-2026-48861.html\\nhttps:\/\/osv.dev\/vulnerability\/EEF-CVE-2026-48861\\nhttps:\/\/github.com\/elixir-mint\/mint\/commit\/fad091454cbb7449b19edb8e1fee12ca7cf28c3a”,”id”:”CVE-2026-48861″,”bulletinFamily”:””,”cwe”:[“CWE-93″],”cvelist”:null,”sourceData”:”elixir-mint mint 0.1.0\\nelixir-mint mint 8db1acff30b6a9433762c18b1e1f891b8c1f74f7″,”sourceHref”:””,”cvss”:{“score”:2.1,”severity”:”LOW”,”vector”:”CVSS:4.0\/AV:L\/AC:L\/AT:P\/PR:N\/UI:N\/VC:N\/VI:L\/VA:N\/SC:N\/SI:L\/SA:N”,”version”:”4.0″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”mint”,”version”:”0.1.0″,”vendor”:”elixir-mint”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
