{"id":"ALPINE-CVE-2023-22796","details":"A regular expression based DoS vulnerability in Active Support \u003c6.1.7.1 and \u003c7.0.4.1. A specially crafted string passed to the underscore method can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability.","modified":"2026-11-03T06:31:48.553359635Z","published":"2023-02-09T20:15:11.487Z","upstream":["CVE-2023-22796"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-22796"}],"affected":[{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}},{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}},{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}},{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}},{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}},{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}},{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}},{"package":{"name":"ruby-activesupport","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/ruby-activesupport?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22796.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
