CVE-2026-119374 · Severity: high · CVSS 7.8 · Published 2026-10-30

SQLite is a widely-used embedded database engine found in mobile phones, browsers, and countless applications. When configured with FTS5 (full-text search) and secure-delete enabled, a crafted database file can trigger a heap buffer overflow during deletion operations, allowing an attacker to corrupt memory and crash the application or potentially execute code.

## How to fix

- Fixed in SQLite 3.54.0

## Technical details

A heap buffer overflow exists in the fts5DoSecureDelete() function when FTS5 is enabled, triggered by corrupted footer key offsets in a malicious FTS5 index. The vulnerability requires the attacker to supply a crafted database file and have the application perform a DELETE operation with secure-delete mode enabled. This results in out-of-bounds writes to heap memory, leading to application crash or potential code execution.

## Affected products
