Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

sqlparse versions before 0.6.0 are vulnerable when the Python or PHP output formats are used. Their quote escaping does not first escape existing backslashes, so crafted SQL can break out of the generated string literal. An attacker who controls the SQL must also have a downstream consumer execute or import the generated snippet, which then runs the injected code with that process's permissions. Upgrade to sqlparse 0.6.0 or later. Avoid the Python and PHP output modes for untrusted SQL until then.
