## What is CVE-2026-59894?

CVE-2026-59894 is a medium-severity code injection vulnerability in andialbrecht sqlparse, published on 17 Aug 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, sqlparse/filters/output.py fails to escape existing backslashes before quotes in sqlparse.format output_format='python' and output_format='php' and the corresponding sqlformat -l modes, allowing crafted SQL to terminate the generated string and inject Python or PHP code when a downstream consumer executes or imports the generated source. This issue is fixed in version 0.6.0.

Weakness: CWE-94 (Improper Control of Generation of Code)

Check this codebase for CVE-2026-59894 and fix it if it is affected.

What it is: CVE-2026-59894 is a medium-severity code injection vulnerability in andialbrecht sqlparse, published on 17 Aug 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-59894 in the wild and no public exploit code.

Affected packages and fixed versions:
- sqlparse (PyPI): affected all versions; fixed in 0.6.0
- sqlparse (PyPI): affected all versions; fixed in 0.6.0
- sqlparse (PyPI): affected all versions; fixed in 0.6.0

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.
