CVE-2018-20505
SQLite 3.25.2, when queries are run on a table with a malformed PRIMARY KEY, allows remote attackers to cause a denial of service (application crash) by leveraging the ability to run arbitrary SQL statements (such as in certain WebSQL use cases).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.89%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
