{"id":"CVE-2025-71461","summary":"Zipline before 4.0.2 Predictable Filenames via Math.random State Recovery","details":"Zipline before 4.0.2 contains a predictable filename vulnerability that allows attackers to infer other users' upload filenames by recovering the Math.random generator state. Attackers with five consecutive gfycat-style filenames can reconstruct the random state to predict previous and future filenames until the instance restarts, exposing private uploads.","aliases":["GHSA-6rg9-q9ww-w2rw"],"modified":"2026-11-14T02:45:13.353434679Z","published":"2026-11-13T09:37:01.263Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71461.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-338"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71461.json"},{"type":"ADVISORY","url":"https://github.com/diced/zipline/security/advisories/GHSA-6rg9-q9ww-w2rw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71461"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/zipline-before-4.0.2-predictable-filenames-via-math-random-state-recovery"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/diced/zipline","events":[{"introduced":"0"},{"fixed":"e8207addba093aa902c9ca22be4bc800ad8930f6"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"4.0.2"}],"source":"DESCRIPTION"}]}}],"versions":["v4.0.1","v4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71461.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
