Affected versions of the peewee package are vulnerable to Regular Expression Denial of Service (ReDoS) due to a nested-repetition regular expression used during FTS5 query validation. The FTS5Model.validate_query routine tokenizes user-supplied search strings with _quote_re.findall(query), and the quoted-string subpattern ("(?:\\.|[^"])*" within a repeated construct) permits catastrophic backtracking on certain inputs.

Peewee 3.17.1 introduces enhancements to address a race condition issue by implementing stricter locking mechanisms around pool connection management.
