An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-39321 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- parse-server (npm): affected all versions; fixed in 8.6.74\n- parse-server (npm): affected all versions; fixed in 8.6.74\n- parse-server (npm): affected from 9.0.0; fixed in 9.8.0-alpha.6\n- parse-server (npm): affected from 9.0.0; fixed in 9.8.0-alpha.6\n- parse (Bitnami): affected all versions; fixed in 8.6.74, 9.8.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-39321/ (Markdown: https://insights.sbomify.com/CVE-2026-39321/index.md)","id":"CVE-2026-39321","markdown":"https://insights.sbomify.com/CVE-2026-39321/index.md","name":"CVE-2026-39321","record":{"aliases":["BIT-parse-2026-39321","GHSA-mmpq-5hcv-hf2v"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Parse Server backend","requires_auth":"none","summary":"An unauthenticated attacker can enumerate valid usernames by measuring response time differences in the login endpoint.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"parse-server","vendor":"parseplatform"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. 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.
