An update that solves four vulnerabilities can now be installed.

## Description:

This update for python3-sqlparse fixes the following issues:

  * CVE-2026-54284: high algorithm complexity when parsing SQL payloads with
    hundreds of nesting levels can lead to denial of service via excessive
    resource consumption (bsc#1275459).
  * CVE-2026-59893: quadratic complexity when processing unmatched dollar-quoted
    literal and multiline-comment delimiters can lead to denial of service
    (bsc#1275461).
  * CVE-2026-59894: improper backlash escaping allows for injection of Python or
    PHP code via a crafted SQL input (bsc#1275460).
  * CVE-2026-71491: quadratic complexity in `group_comments` when processing
    comment-only statements can lead to denial of services (bsc#1275466).
