Vulnerability from csaf_redhat - Published: 2026-10-01 20:18 - Updated: 2026-10-02 17:36A flaw was found in sqlparse, a Python module for parsing SQL. A remote attacker could exploit a vulnerability in the TokenList construction and string conversion processes, specifically when handling nested token subtrees. This flaw leads to quadratic CPU consumption, which can result in a Denial of Service (DoS) by exhausting system resources before internal limits are reached.

A flaw was found in sqlparse, a Python module for parsing SQL. A remote attacker could exploit this vulnerability by providing specially crafted SQL input. This flaw causes inefficient processing of certain SQL patterns, leading to excessive CPU consumption and potentially a Denial of Service (DoS) condition, making the application unresponsive.
A flaw was found in sqlparse, a Python module for parsing SQL. A remote attacker could exploit this vulnerability by providing specially crafted SQL input that contains numerous comment-only statements. This could cause the `group_comments` function to repeatedly rescan these statements, leading to excessive CPU consumption and a Denial of Service (DoS) for the application using the parser.
