{"id":"CVE-2026-32702","state":"PUBLISHED","title":"Cleanuparr has Username Enumeration via Timing Attack","description":"Cleanuparr is a tool for automating the cleanup of unwanted or blocked files in Sonarr, Radarr, and supported download clients like qBittorrent. From 2.7.0 to 2.8.0, the /api/auth/login endpoint contains a logic flaw that allows unauthenticated remote attackers to enumerate valid usernames by measuring the application's response time. It appears that the hashing function, which is the most time-consuming part of the process by design, occurs as part of the VerifyPassword function. With the short circuits occurring before the hashing function, a timing differential is introduced that exposes validity to the actor. This vulnerability is fixed in 2.8.1.","publishedAt":"2026-03-13T21:09:00.127Z","updatedAt":"2026-03-16T16:47:53.284Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["Cleanuparr Cleanuparr"],"affected":[{"vendor":"Cleanuparr","product":"Cleanuparr","versions":[{"version":">= 2.7.0, <= 2.8.0","status":"affected"}]}],"references":["https://github.com/Cleanuparr/Cleanuparr/security/advisories/GHSA-gjmf-m27r-2c9v"],"weaknesses":["CWE-208"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/32xxx/CVE-2026-32702.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-32702","state":"PUBLISHED","datePublished":"2026-03-13T21:09:00.127Z","dateUpdated":"2026-03-16T16:47:53.284Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-13T14:33:42.823Z"},"containers":{"cna":{"title":"Cleanuparr has Username Enumeration via Timing Attack","descriptions":[{"lang":"en","value":"Cleanuparr is a tool for automating the cleanup of unwanted or blocked files in Sonarr, Radarr, and supported download clients like qBittorrent.
