Uncontrolled Recursion

Affected versions of this package are vulnerable to Uncontrolled Recursion due to the parsing of heavily nested lists. An attacker can cause the application to crash by submitting a specially crafted list that triggers a RecursionError.

Note: The impact depends on the use, so anyone parsing a user input with sqlparse.parse() is affected.

How to fix Uncontrolled Recursion?

Upgrade sqlparse to version 0.5.0 or higher.

Regular Expression Denial of Service (ReDoS)

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). The formatter function that strips comments from a SQL contains a regular expression that is vulnerable to ReDoS. The regular expression may cause exponential backtracking on strings containing many repetitions of \r\n in SQL comments.

How to fix Regular Expression Denial of Service (ReDoS)?

Upgrade sqlparse to version 0.4.2 or higher.
