{"id":"CVE-2026-107911","published":"2026-10-09T06:17:12.620","lastModified":"2026-10-09T17:16:46.130","description":"A type confusion vulnerability in the _read_flags function (src/commands/cmd_dispatcher.c) in FalkorDB before 4.20.0 allows a remote authenticated attacker who can run GRAPH.QUERY to cause a denial of service and possibly disclose or corrupt memory. The function accepts a --bolt argument from any client and casts the following command argument, a Redis string object, to a Bolt client structure without checking its origin; the result-set code then dereferences pointers read from that object. The argument is parsed even when the Bolt endpoint is disabled, so default configurations are affected.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-843"],"vendors":[],"products":[],"references":[{"url":"https://github.com/FalkorDB/FalkorDB/commit/0b11a00b34b25c4d4fdfe55f0a35c8a00593bd7d","tags":[]},{"url":"https://github.com/FalkorDB/FalkorDB/pull/2170","tags":[]},{"url":"https://github.com/FalkorDB/FalkorDB/releases/tag/v4.20.0","tags":[]}],"exploitRefs":[{"url":"https://github.com/FalkorDB/FalkorDB/commit/0b11a00b34b25c4d4fdfe55f0a35c8a00593bd7d","tags":[]},{"url":"https://github.com/FalkorDB/FalkorDB/pull/2170","tags":[]},{"url":"https://github.com/FalkorDB/FalkorDB/releases/tag/v4.20.0","tags":[]}],"hasPoc":true,"ai":{"summary":"A type confusion vulnerability in FalkorDB's command dispatcher allows authenticated attackers to cause memory corruption and denial of service by exploiting improper casting of Bolt client structures.
