CVE-2026-107911

Status: DeferredHigh (7.7)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vulnerabilidad de confusión de tipos en servicio Redis remoto que requiere autenticación previa (PR:L). El atacante causa DoS mediante dereference de punteros malformados, accede a memoria y puede corromper datos sin privilegios elevados (VC:H, VI:H, VA:H).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
