Vulnerability Title

SQLite before 3.54.0 Information Disclosure via WAL Page Size Mismatch

Source: CVE Program / CVE List V5

Vulnerability Description

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.
