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.","state":0,"publishedAt":"2026-09-24T17:37:59.28+00:00","modifiedAt":"2026-09-28T14:57:19.854+00:00","affected":[{"ecosystem":"Vendor product","name":"habitica","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"HabitRPG\",\n                    \"product\": \"habitica\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.172.1, < 5.48.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/HabitRPG/habitica/security/advisories/GHSA-x772-22c9-gq58","https://github.com/HabitRPG/habitica/commit/7b7dc255dff1564935675399ff168e8a91b8afca","https://github.com/HabitRPG/habitica/releases/tag/v5.48.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54461","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54461","identifiers":["CVE-2026-54461"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
