Tailscale traced a database corruption incident to a 16-year-old bug in SQLite's WAL (Write-Ahead Log) reset mechanism. The discovery highlights a long-standing edge-case flaw in SQLite where WAL resets under certain failure conditions can silently corrupt data.
Background
SQLite is one of the most widely deployed database engines globally, used in everything from mobile apps to server applications. WAL mode is its default write-ahead logging mechanism for concurrency and crash recovery.
