CVE-2018-20346 is an integer overflow vulnerability in SQLite versions prior to 3.25.3, specifically affecting the FTS3 extension. This flaw, dubbed "Magellan," allows remote attackers to execute arbitrary code by crafting SQL statements that manipulate FTS3 shadow tables. With a CVSS score of 8.1 (High), exploitation requires high attack complexity but can lead to complete compromise of confidentiality, integrity, and availability. There is no public exploit code available, nor is there evidence of active exploitation or significant community discussion.
