{"id":"CVE-2026-33202","aliases":["GHSA-73f9-jhhh-hr5m"],"url":"https://o3.security/vulnerability/CVE-2026-33202","summary":"Rails Active Storage has possible glob injection in its DiskService","details":"Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#delete_prefixed` passes blob keys directly to `Dir.glob` without escaping glob metacharacters. If a blob key contains attacker-controlled input or custom-generated keys with glob metacharacters, it may be possible to delete unintended files from the storage directory. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.","published":"2026-03-23T23:34:52.715Z","modified":"2026-08-07T11:49:52.480562420Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"activestorage","fixedVersion":"8.1.2.1"},{"ecosystem":"RubyGems","name":"activestorage","fixedVersion":"8.0.4.1"},{"ecosystem":"RubyGems","name":"activestorage","fixedVersion":"7.2.3.1"}],"fix":{"url":"https://github.com/rails/rails/commit/8c9676b803820110548cdb7523800db43bc6874c","label":"rails/rails@8c9676b"},"references":[{"type":"WEB","url":"https://github.com/rails/rails/releases/tag/v7.2.3.1"},{"type":"WEB","url":"https://github.com/rails/rails/releases/tag/v8.0.4.1"},{"type":"WEB","url":"https://github.com/rails/rails/releases/tag/v8.1.2.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33202.json"},{"type":"ADVISORY","url":"https://github.com/rails/rails/security/advisories/GHSA-73f9-jhhh-hr5m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33202"},{"type":"FIX","url":"https://github.com/rails/rails/commit/8c9676b803820110548cdb7523800db43bc6874c"},{"type":"FIX","url":"https://github.com/rails/rails/commit/955284d26e469a9c026a4eee5b21f0414ab0bccf"},{"type":"FIX","url":"https://github.com/rails/rails/commit/fa19073546360856e9f4dab221fc2c5d73a45e82"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:49:52.480562420Z"}}
