NVD Description

Note: Versions mentioned in the description apply only to the upstream python-3.13 package and not the python-3.13 package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

There is an issue in CPython when using bytes.decode(&#34;unicode_escape&#34;, error=&#34;ignore|replace&#34;). If you are not using the "unicode_escape" encoding or an error handler your usage is not affected. To work-around this issue you may stop using the error= handler and instead wrap the bytes.decode() call in a try-except catching the DecodeError.
