{"schema":"threatline.record/2","record":{"id":"CVE-2026-7827","aliases":[],"summary":"Stack-based buffer overflow in FalkorDB _RdbLoadEntity via unbounded property count in crafted RDB","details":"A stack-based buffer overflow in the _RdbLoadEntity function of the RDB graph decoders (src/serializers/decoders/*/decode_graph_entities.c) in FalkorDB before 4.18.4 allows a remote attacker who can issue Redis replication commands (for example, against an instance with no password configured) to cause a denial of service and possibly execute arbitrary code by supplying a crafted RDB stream with an attacker-controlled entity property count. The count sizes two variable-length arrays on the thread stack with no upper bound, and the decoder then fills them with attacker-supplied values.","categories":["Unclassified"],"product":"FalkorDB","vendor":"FalkorDB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-7827","source_modified_at":"2026-10-09T16:47:46.031Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FalkorDB","vendor":"FalkorDB","versions":[{"version":"0","lessThan":"4.18.4","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-7827","source_modified_at":"2026-10-09T16:47:46.031Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"FalkorDB","ecosystem":null},"version":"4.18.4","basis":"first unaffected version stated in the CVE record"}],"cvss":9.2,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00584,"percentile":0.47242,"score_date":"2026-10-23"},"published_at":"2026-10-09T04:04:29.094Z","modified_at":"2026-10-09T16:47:46.031Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-7827","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-09T16:47:46.031Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-7827","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/FalkorDB/FalkorDB/pull/1973","tags":["patch"]},{"source":"CVE List","url":"https://github.com/FalkorDB/FalkorDB/commit/7d15431aadf37588fadc2578b90c3afb5e8daa94","tags":["patch"]},{"source":"CVE List","url":"https://github.com/FalkorDB/FalkorDB/releases/tag/v4.18.4","tags":["release-notes"]}],"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":"2026-10-09T16:16:19.507878Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-09T16:47:46.031Z","content_hash":"f084f81fa628aecc9568500eed42d58d0761b0b1b9641f3851a12d7593379042"}}
