Python Library sqlparse < 0.6.0 Multiple Vulnerabilities

high Nessus Plugin ID 338624

Synopsis

A Python library installed on the remote host is affected by multiple vulnerabilities.

Description

The version of the sqlparse Python library installed on the remote host is prior to 0.6.0. It is, therefore, affected by multiple vulnerabilities:

 - A denial of service vulnerability exists in sqlparse due to the regular expressions used by the lexer to match dollar-quoted strings and multiline comments. An unauthenticated, remote attacker can exploit this, by supplying specially crafted SQL input, to cause catastrophic backtracking and exhaust available resources. (CVE-2026-59893)

 - A denial of service vulnerability exists in sqlparse in the token list handling implemented in sqlparse/sql.py. An unauthenticated, remote attacker can exploit this, by supplying deeply nested SQL input, to consume excessive CPU and memory resources. (CVE-2026-54284)

 - A denial of service vulnerability exists in sqlparse in the comment grouping logic implemented in sqlparse/engine/grouping.py. An unauthenticated, remote attacker can exploit this, by supplying specially crafted SQL input containing many comments, to consume excessive resources due to repeated rescanning of the token stream. (CVE-2026-71491)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to sqlparse version 0.6.0 or later.
