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.","state":0,"publishedAt":"2026-10-09T05:08:14.899+00:00","modifiedAt":"2026-10-09T16:47:39.583+00:00","affected":[{"ecosystem":"https://github.com/FalkorDB/FalkorDB","name":"FalkorDB","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"FalkorDB\",\n                    \"product\": \"FalkorDB\",\n                    \"collectionURL\": \"https://github.com/FalkorDB/FalkorDB\",\n                    \"repo\": \"https://github.com/FalkorDB/FalkorDB\",\n                    \"modules\": [\n                        \"GRAPH.QUERY command argument parsing\"\n                    ],\n                    \"programFiles\": [\n                        \"src/commands/cmd_dispatcher.c\"\n                    ],\n                    \"programRoutines\": [\n                        {\n                            \"name\": \"_read_flags\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:falkordb:falkordb:*:*:*:*:*:*:*:*\"\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"4.20.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/FalkorDB/FalkorDB/pull/2170","https://github.com/FalkorDB/FalkorDB/commit/0b11a00b34b25c4d4fdfe55f0a35c8a00593bd7d","https://github.com/FalkorDB/FalkorDB/releases/tag/v4.20.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107911","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107911","identifiers":["CVE-2026-107911"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
