Prior to 9.8.0-alpha.6 and 8.6.74, he login endpoint response time differs measurably depending on whether the submitted username or email exists in the database. When a user is not found, the server responds immediately. When a user exists but the password is wrong, a bcrypt comparison runs first, adding significant latency. This timing difference allows an unauthenticated attacker to enumerate valid usernames. This vulnerability is fixed in 9.8.0-alpha.6 and 8.6.74."}], "lastModified": "2026-04-15T17:20:11.180", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "09BF568A-BD39-48BE-A23A-059EC90E2F98", "versionEndExcluding": "8.6.74"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "505A2B01-2F11-48C8-BA71-66D6FEB856B1", "versionEndExcluding": "9.8.0", "versionStartIncluding": "9.0.0"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "510B10D0-84FF-464C-A94F-2A81B4C82DA6"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "65C4D465-733A-464D-8BDC-BA29669CF48B"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha3:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "D125D774-F201-4028-8929-E5613205E151"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha4:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "E71F69E4-172B-4E46-B96D-FE4268E0E3B3"}, {"criteria": "cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha5:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "820B096D-053D-47A3-9E8B-65DF698221C0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
