{"id":"CVE-2026-104057","summary":"Podgrab Unauthenticated DoS via Concurrent Map Access in WebSocket Handler","details":"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.","modified":"2026-10-08T02:49:16.293287896Z","published":"2026-10-01T18:04:01.135Z","database_specific":{"cwe_ids":["CWE-362"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104057.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104057.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104057"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/podgrab-unauthenticated-dos-via-concurrent-map-access-in-websocket-handler"},{"type":"PACKAGE","url":"https://github.com/akhilrex/podgrab"},{"type":"ARTICLE","url":"https://gist.github.com/mansurmavlankulov/022bc672583687ccb34dcf4cb31b6188"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/akhilrex/podgrab","events":[{"introduced":"0"},{"last_affected":"032248091294dbf5b6a439a5afd93788a7cc647f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-104057.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
