OESA-2026-4219 python-sqlparse security update

A non-validating SQL parser. Security Fixes: sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, TokenList construction and string conversion in sqlparse/sql.py repeatedly flatten nested token subtrees constructed by groupparenthesis and groupcase, causing quadratic CPU...

CVE-2026-59894

A flaw was found in sqlparse, a non-validating SQL parser module for Python. When generating Python or PHP code snippets, the sqlparse.format function fails to properly escape backslashes before quotes in SQL strings. This vulnerability allows a local attacker, by providing crafted SQL, to break...

Summary The documented Python and PHP output modes generate source-code snippets from caller-supplied SQL. Their output filters escape quote characters without first escaping existing backslashes. Crafted SQL can therefore neutralize the generated quote escape, terminate the intended language...

PT-2026-80668

Summary A comment-only statement -- c n may cause a Denial of Service DoS. Details Location: sqlparse/engine/grouping.py:331-341 group comments, invoked first in group at grouping.py:439. Reachable via sqlparse.parse and sqlparse.formatsql, strip comments=True. A statement made of many single-lin...

CVE-2026-54284

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, TokenList construction and string conversion in sqlparse/sql.py repeatedly flatten nested token subtrees constructed by groupparenthesis and groupcase, causing quadratic CPU consumption through sqlparse.parse,...

CVE-2026-59893

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, SQLREGEX 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,...

CVE-2026-71491: Uncontrolled Resource Consumption

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, groupcomments in sqlparse/engine/grouping.py repeatedly rescans comment-only statements before the MAXGROUPINGTOKENS guard, causing quadratic CPU consumption through sqlparse.parse and sqlparse.formatsql, stripcomments=Tru...

CVE-2026-54284: Inefficient Algorithmic Complexity

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, TokenList construction and string conversion in sqlparse/sql.py repeatedly flatten nested token subtrees constructed by groupparenthesis and groupcase, causing quadratic CPU consumption through sqlparse.parse,...
