## Overview

SQLite before 3.54.0 contains an information disclosure vulnerability that allows attackers to read uninitialized page-cache memory by supplying a WAL file with an undersized page size. Attackers can craft a database and WAL file whose oversized record payload makes queries like substr() return stale bytes, disclosing other table rows and internal pointers.

## Affected

- `SQLite < 3.54.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
