Machine-written summary

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

sqlparse before 0.6.0 has a regular expression denial of service flaw in its lexer for dollar-quoted literals and multiline comments. An attacker who can supply SQL text to an application that calls parse, format or split can cause sustained CPU exhaustion, with no authentication needed. Upgrade to sqlparse 0.6.0 or later.
