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.","state":0,"publishedAt":"2026-04-07T18:16:43.09+00:00","modifiedAt":"2026-06-17T10:41:55.003+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6.3,"severity":"MEDIUM"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7,"severity":"LOW"}],"references":["https://github.com/parse-community/parse-server/pull/10398","https://github.com/parse-community/parse-server/pull/10399","https://github.com/parse-community/parse-server/security/advisories/GHSA-mmpq-5hcv-hf2v"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-39321","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-208"],"productCriteria":["cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*","cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha1:*:*:*:node.js:*:*","cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha2:*:*:*:node.js:*:*","cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha3:*:*:*:node.js:*:*","cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha4:*:*:*:node.js:*:*","cpe:2.3:a:parseplatform:parse-server:9.8.0:alpha5:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-04-07T18:16:43.090","lastModified":"2026-06-17T10:41:55.003"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
