sqlparse through 0.6.0 PHP Code Injection via output_format='php'
sqlparse through 0.6.0 contains a PHP code injection vulnerability that allows attackers to inject PHP expressions by supplying SQL text containing unescaped dollar signs. Attackers can embed ${expr} or {${expr}} sequences that OutputPHPFilter places in double-quoted strings, executing arbitrary PHP code when the generated snippet runs.
sqlparse: Reindentation of tuple lists causes near-cap quadratic CPU consumption
sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, sqlparse.format(sql, reindent=True) and sqlformat --reindent route attacker-controlled parenthesized tuple lists through ReindentFilter._get_offset() in sqlparse/filters/reindent.py, where _flatten_up_to_token() repeatedly rebuilds and joins the statement prefix. Thousands of offset calculations walk an expanding token tree, producing quadratic CPU consumption for inputs that remain below MAX_GROUPING_TOKENS and causing request delays, reduced throughput, or worker starvation. This issue is fixed in version 0.6.0.
sqlparse: Generated Python and PHP snippets allow SQL string breakout through unescaped backslashes
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.
