{"id":"CVE-2026-54461","summary":"Habitica: Regex Injection / ReDoS in Member Search","details":"Habitica is a habit tracker application that treats goals like a role-playing game. From 4.172.1 until 5.48.2, a query parameter on Habitica's /api/v3/groups/:groupId/members route is not sanitized before being interpreted as a regular expression. An authenticated caller can supply a computationally expensive regular expression that degrades application performance or halts Node.js processes. This issue is fixed in version 5.48.2.","aliases":["GHSA-x772-22c9-gq58"],"modified":"2026-09-26T03:45:56.315600317Z","published":"2026-09-24T17:37:59.280Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-1333"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54461.json"},"references":[{"type":"WEB","url":"https://github.com/HabitRPG/habitica/releases/tag/v5.48.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54461.json"},{"type":"ADVISORY","url":"https://github.com/HabitRPG/habitica/security/advisories/GHSA-x772-22c9-gq58"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54461"},{"type":"FIX","url":"https://github.com/HabitRPG/habitica/commit/7b7dc255dff1564935675399ff168e8a91b8afca"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/habitrpg/habitica","events":[{"introduced":"c055d438953cb7e0fe3439545bbb00bf937544d2"},{"fixed":"7b7dc255dff1564935675399ff168e8a91b8afca"},{"fixed":"dcbb491bd2a1e145ebaaa8cccc08de47cebce42f"}],"database_specific":{"extracted_events":[{"introduced":"4.172.1"},{"fixed":"5.48.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54461.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
