The CVE issue is fixed by 3 different commits between the releases 2.14.0 (for Smithy lexer), 2.15.0 (for SQL+Jinja lexers) and 2.15.1 (for Java properties) as per: https://pyup.io/posts/pyup-discovers-redos-vulnerabilities-in-top-python-packages-part-2/ 1. Smithy lexer commit from 2.14.0 release applies successfully on 2.11.2 version. Commit: https://github.com/pygments/pygments/commit/dd52102c38ebe78cd57748e09f38929fd283ad04 Hence, backported the patch as CVE-2022-40896.patch. 2.
