Attackers on the agent-to-agent path or malicious peers can supply substituted content with forged CRC32 corrections that passes per-piece checks, poisoning the cache with attacker-chosen container image layers or manifests that are re-seeded and executed by other hosts.","published":"2026-08-18T18:19:34.343","modified":"2026-08-18T18:19:34.343","cvss":{"score":9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/uber/kraken"},{"type":"WEB","url":"https://github.com/uber/kraken/blob/master/lib/torrent/storage/agentstorage/torrent.go"},{"type":"WEB","url":"https://github.com/uber/kraken/issues/638"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/kraken-agents-peer-to-peer-download-cache-poisoning-via-digest-verification-bypass"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T18:19:34.343"}}
