DescriptionCVE.org

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, SQL_REGEX in sqlparse/keywords.py and the per-position loop in sqlparse/lexer.py repeatedly scan unmatched dollar-quoted literal and multiline-comment delimiters, causing quadratic CPU consumption through sqlparse.parse(), sqlparse.format(), and sqlparse.split(). This issue is fixed in version 0.6.0.

AnalysisAI

CPU exhaustion via ReDoS in sqlparse affects all Python applications that pass caller-controlled SQL text to sqlparse.parse(), sqlparse.format(), or sqlparse.split() prior to version 0.6.0. The root cause is a backreference regex pattern in the dollar-quoted literal lexer that, combined with the per-position lexer loop, produces O(n²) CPU complexity when processing inputs containing many unique, unclosed dollar-quote openers or multiline comment delimiters — making it trivially exploitable from the network with no authentication. No public exploit code or CISA KEV listing has been identified at time of analysis, but the fix commit includes a purpose-built benchmark script that doubles as a functional reproduction guide.
