{"id":"CVE-2026-104192","state":"PUBLISHED","title":"DragonflyDB stream RDB deserialization double-free","description":"Dragonfly is an in-memory data store built for modern application workloads. Prior to 1.40, OpaqueObjLoader::CreateStream in src/server/rdb_load.cc can associate one streamNACK with a consumer group's global PEL and a consumer-local PEL, then free the shared object when a duplicate consumer entry is rejected. Cleanup subsequently frees the same object again. In the default configuration, where Dragonfly ships with authentication disabled, an unauthenticated client can trigger the double-free by sending a crafted serialized stream to RESTORE, causing allocator corruption, denial of service, and potentially attacker-controlled code execution as the Dragonfly service account. The source fix has not yet been mapped to a published release.","publishedAt":"2026-10-13T14:42:54.248Z","updatedAt":"2026-10-13T15:26:00.663Z","severity":{"score":9.6,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["dragonflydb dragonfly"],"affected":[{"vendor":"dragonflydb","product":"dragonfly","versions":[{"version":"< 1.40","status":"affected"}]}],"references":["https://github.com/dragonflydb/dragonfly/security/advisories/GHSA-cg35-6jf4-crfh","https://github.com/dragonflydb/dragonfly/pull/7929","https://github.com/dragonflydb/dragonfly/commit/6c6b27a5cfd03d67eb9583ab84a0f0709e3bc77e"],"weaknesses":["CWE-415"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104192.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104192","state":"PUBLISHED","datePublished":"2026-10-13T14:42:54.248Z","dateUpdated":"2026-10-13T15:26:00.663Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-01T18:54:15.119Z"},"containers":{"cna":{"title":"DragonflyDB stream RDB deserialization double-free","descriptions":[{"lang":"en","value":"Dragonfly is an in-memory data store built for modern application workloads.
