{"id":"ALPINE-CVE-2020-10663","details":"The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent.","modified":"2026-09-11T10:17:51.359596123Z","published":"2020-04-28T21:15:11.667Z","upstream":["CVE-2020-10663"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-10663"}],"affected":[{"package":{"name":"ruby","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.5.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-10663.json"}},{"package":{"name":"ruby","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/ruby?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-con
