{"id":"CVE-2023-23925","summary":"Switcher Client contains Regular Expression Denial of Service (ReDoS)","details":"Switcher Client is a JavaScript SDK to work with Switcher API which is cloud-based Feature Flag. Unsanitized input flows into Strategy match operation (EXIST), where it is used to build a regular expression. This may result in a Regular expression Denial of Service attack (reDOS). This issue has been patched in version 3.1.4. As a workaround, avoid using Strategy settings that use REGEX in conjunction with EXIST and NOT_EXIST operations.\n","aliases":["GHSA-wqxw-8h5g-hq56"],"modified":"2026-04-02T08:49:23.360068Z","published":"2023-02-03T19:05:30.909Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-1333","CWE-400"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/23xxx/CVE-2023-23925.json"},"references":[{"type":"WEB","url":"https://github.com/switcherapi/switcher-client-master/releases/tag/v3.1.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/23xxx/CVE-2023-23925.json"},{"type":"ADVISORY","url":"https://github.com/switcherapi/switcher-client-master/security/advisories/GHSA-wqxw-8h5g-hq56"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-23925"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/switcherapi/switcher-client-js","events":[{"introduced":"0"},{"fixed":"9a18960af900d9f71f7213594e73bf7f6e91e04b"}]}],"versions":["v1.0.1","v1.0.2","v1.0.3","v1.0.4","v1.0.5","v1.0.6","v1.0.7","v1.0.8","v2.0.0","v2.0.1","v2.0.2","v2.0.3","v2.0.4","v2.0.5","v2.0.6","v2.0.7","v2.0.8","v2.0.9","v2.1.0","v2.1.1","v3.0.0","v3.0.1","v3.1.0","v3.1.1","v3.1.2","v3.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-23925.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/switcherapi/switcher-client-master","events":[{"introduced":"0"},{"fixed":"9a18960af900d9f71f7213594e73bf7f6e91e04b"}]}],"versions":["v1.0.1","v1.0.2","v1.0.3","v1.0.4","v1.0.5","v1.0.6","v1.0.7","v1.0.8","v2.0.0","v2.0.1","v2.0.2","v2.0.3","v2.0.4","v2.0.5","v2.0.6","v2.0.7","v2.0.8","v2.0.9","v2.1.0","v2.1.1","v3.0.0","v3.0.1","v3.1.0","v3.1.1","v3.1.2","v3.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-23925.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}]}
