{"id":"ALPINE-CVE-2020-25613","details":"An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack.","modified":"2026-09-11T10:17:51.413956541Z","published":"2020-10-06T13:15:13.823Z","upstream":["CVE-2020-25613"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-25613"}],"affected":[{"package":{"name":"ruby","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.5.8-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.6.6-r3"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-25613.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.0"},{"fixed":"2.7.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source
