{"id":"CVE-2021-22880","aliases":["GHSA-8hc4-xxm3-5ppp"],"url":"https://o3.security/vulnerability/CVE-2021-22880","summary":"Active Record subject to Regular Expression Denial-of-Service (ReDoS)","details":"The PostgreSQL adapter in Active Record before 6.1.2.1, 6.0.3.5, 5.2.4.5 suffers from a regular expression denial of service (REDoS) vulnerability. Carefully crafted input can cause the input validation in the `money` type of the PostgreSQL adapter in Active Record to spend too much time in a regular expression, resulting in the potential for a DoS attack. This only impacts Rails applications that are using PostgreSQL along with money type columns that take user input.","published":"2021-02-11T18:15:17.333Z","modified":"2026-09-09T03:30:26.283510041Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"RubyGems","name":"activerecord","fixedVersion":"5.2.4.5"},{"ecosystem":"RubyGems","name":"activerecord","fixedVersion":"6.0.3.5"},{"ecosystem":"RubyGems","name":"activerecord","fixedVersion":"6.1.2.1"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MO5OJ3F4ZL3UXVLJO6ECANRVZBNRS2IH/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XQ3NS4IBYE2I3MVMGAHFZBZBIZGHXHT3/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20210805-0009/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2021/dsa-4929"},{"type":"FIX","url":"https://discuss.rubyonrails.org/t/cve-2021-22880-possible-dos-vulnerability-in-active-record-postgresql-adapter/77129"},{"type":"FIX","url":"https://hackerone.com/reports/1023899"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-09T03:30:26.283510041Z"}}
