Mike Bayer has proposed a fix for this issue in the main branch:

replace "dot" with "set not containing whitespace" https://gerrit.sqlalchemy.org/c/sqlalchemy/mako/+/4091

python3-mako: upgrade 1.2.2 -> 1.2.3
280a1f5 
Released: Thu Sep 22 2022
* bug

 - [bug] [lexer]

   * Fixed issue in lexer in the same category as that of #366 where the regexp
     used to match an end tag didn’t correctly organize for matching characters
     surrounded by whitespace, leading to high memory / interpreter hang if a
     closing tag incorrectly had a large amount of unterminated space in it.
     Credit to Sebastian Chnelik for locating the issue.

    As Mako templates inherently render and directly invoke arbitrary Python
    code from the template source, it is never appropriate to create templates
    that contain untrusted input.
