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."}],"affected":[{"vendor":"FalkorDB","product":"FalkorDB","collectionURL":"https://github.com/FalkorDB/FalkorDB","repo":"https://github.com/FalkorDB/FalkorDB","modules":["GRAPH.QUERY command argument parsing"],"programFiles":["src/commands/cmd_dispatcher.c"],"programRoutines":[{"name":"_read_flags"}],"cpes":["cpe:2.3:a:falkordb:falkordb:*:*:*:*:*:*:*:*"],"defaultStatus":"unaffected","versions":[{"version":"0","lessThan":"4.20.0","status":"affected","versionType":"semver"}]}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-843","description":"CWE-843 Access of Resource Using Incompatible Type ('Type Confusion')"}]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV4_0":{"version":"4.0","vectorString":"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","baseScore":7.7,"baseSeverity":"HIGH"}},{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.5,"baseSeverity":"HIGH"}}],"solutions":[{"lang":"en","value":"Upgrade FalkorDB to version 4.20.0 or later.
