{"schema":"threatline.record/2","record":{"id":"CVE-2026-104192","aliases":["GHSA-cg35-6jf4-crfh"],"summary":"DragonflyDB stream RDB deserialization double-free","details":"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.","categories":["Unclassified"],"product":"dragonfly","vendor":"dragonflydb","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104192","source_modified_at":"2026-10-13T15:26:00.663Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"dragonfly","vendor":"dragonflydb","versions":[{"version":"< 1.40","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":9.6,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00276,"percentile":0.19028,"score_date":"2026-10-23"},"published_at":"2026-10-13T14:42:54.248Z","modified_at":"2026-10-13T15:26:00.663Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104192","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T15:26:00.663Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104192","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/dragonflydb/dragonfly/security/advisories/GHSA-cg35-6jf4-crfh","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/dragonflydb/dragonfly/pull/7929","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/dragonflydb/dragonfly/commit/6c6b27a5cfd03d67eb9583ab84a0f0709e3bc77e","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-13T15:25:47.878490Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T15:26:00.663Z","content_hash":"7b6a175f0e85d5bf328730aa3679b8ebd1e03356a59b43ab66f3f385980f478e"}}
