PatchTheCVECVE-2026-59894: sqlparse is a non-validating SQL parser module for Python
CVE-2026-59894 is a medium-severity flaw (CVSS 6.2) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
