{"id":"CVE-2026-104057","state":"PUBLISHED","title":"Podgrab Unauthenticated DoS via Concurrent Map Access in WebSocket Handler","description":"Podgrab contains an unauthenticated denial-of-service vulnerability caused by unsynchronized concurrent access to shared maps (activePlayers and allConnections) in its WebSocket handler, where Wshandler and HandleWebsocketMessages goroutines read and write these maps without a mutex. A remote attacker can open multiple WebSocket connections to the /ws endpoint and send messages in a loop to trigger a Go runtime data race that crashes the process, causing a denial of service that requires operator intervention to restore service.","publishedAt":"2026-10-01T18:04:01.135Z","updatedAt":"2026-10-13T11:20:52.409Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["akhilrex podgrab"],"affected":[{"vendor":"akhilrex","product":"podgrab","packageURL":"pkg:github/akhilrex/podgrab","defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"032248091294dbf5b6a439a5afd93788a7cc647f","versionType":"git"}],"repo":"https://github.com/akhilrex/podgrab"}],"references":["https://gist.github.com/mansurmavlankulov/022bc672583687ccb34dcf4cb31b6188","https://www.vulncheck.com/advisories/podgrab-unauthenticated-dos-via-concurrent-map-access-in-websocket-handler"],"weaknesses":["CWE-362"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104057.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104057","state":"PUBLISHED","datePublished":"2026-10-01T18:04:01.135Z","dateUpdated":"2026-10-13T11:20:52.409Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-10-01T18:02:50.080Z"},"containers":{"cna":{"title":"Podgrab Unauthenticated DoS via Concurrent Map Access in WebSocket Handler","descriptions":[{"lang":"en","value":"Podgrab contains an unauthenticated denial-of-service vulnerability caused by unsynchronized concurrent access to shared maps (activePlayers and allConnections) in its WebSocket handler, where Wshandler and HandleWebsocketMessages goroutines read and write these maps without a mutex.
