CVE-2026-119591 is a medium-severity vulnerability in SQLite, published on 30 Oct 2026. 

### Official description

SQLite before 3.54.0 contains a stack exhaustion vulnerability in countOfViewOptimization() that allows attackers to crash the host process via count(*) over a large multi-row VALUES clause. Attackers supplying SQL or a database file with a crafted view can trigger deeply nested TK_PLUS expressions whose recursive freeing in sqlite3ExprDeleteNN() exhausts the C stack, causing denial of service.

Weakness: CWE-674 (Uncontrolled Recursion)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-119591 and fix it if it is affected.

What it is: CVE-2026-119591 is a medium-severity vulnerability in SQLite, published on 30 Oct 2026. 
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-119591 exists.

Affected product: SQLite. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
