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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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","score":6.3,"severity":null}],"references":["https://github.com/parse-community/parse-server/security/advisories/GHSA-mmpq-5hcv-hf2v","https://github.com/parse-community/parse-server/pull/10398","https://github.com/parse-community/parse-server/pull/10399"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-19818","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Apr 7, 2026, 6:11:10 PM","dateUpdated":"Apr 7, 2026, 7:58:57 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
