MEDIUM 4.1EPSS 0.16%

Does this matter?

Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.

Description

The YugabyteDB tablet server contains a flaw in its YCQL query handling that can trigger a null pointer dereference when processing certain malformed inputs. An authenticated attacker could exploit this issue to crash the YCQL tablet server, resulting in a denial of service.
