CVE-2026-119376 · Severity: medium · CVSS 5.5 · Published 2026-10-30

SQLite is a lightweight database engine used in virtually all mobile phones and many applications worldwide. A flaw in how SQLite processes chained COLLATE operators can cause the application to crash when given specially crafted SQL queries, potentially leading to denial of service in applications that accept untrusted SQL or database views.

## Quick answers

**Is CVE-2026-119376 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-119376 being exploited in the wild.

**How severe is CVE-2026-119376?** Medium severity, with a CVSS score of 5.5, published 30 October 2026.

**Which products and versions are affected?** SQLite before 3.54.0.

**Is there a fix for CVE-2026-119376?** Yes: fixed in SQLite 3.54.0. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-119376 attacked?** It is attacked with local access or over the network, in a software library.

**Am I affected by CVE-2026-119376?** Check whether you run SQLite at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in SQLite 3.54.0

## Technical details

SQLite before version 3.54.0 fails to enforce the SQLITE_LIMIT_EXPR_DEPTH recursion limit when processing chained COLLATE postfix operators in SQL expressions. An attacker can supply approximately 175,000 chained COLLATE operators in a SQL query or untrusted database view to trigger unbounded recursion in the sqlite3WalkExprNN() function, exhausting the stack and crashing the process.

## Affected products

- SQLite before 3.54.0

## Timeline

- 2026-10-30: disclosed
- 2026-10-16: patched: Version 3.54.1 released
