I have made the requested changes; please review again

You're correct that .rpartition(']') was unnecessary here so I changed it back to the original .partition(']'). I originally changed it because it seemed cleaner to me but it isn't necessary to fix this issue.

Hi @miss-islington and @gpshead - how do I ensure I'm using a version of Python with this vulnerability fixed?

I'm supporting a team that uses hardened containers from Iron Bank and I don't believe the approved containers will get the back port updates.

Since 3.11 is the newest version mentioned here for a back port, does the initial release of 3.12 include this fix?

CharlieZhao95 · 2024-11-29T01:35:43Z

Since 3.11 is the newest version mentioned here for a back port, does the initial release of 3.12 include this fix?

The release date of Pyton3.12 is 2023-10, so of course, 3.12 contains this patch. BTW miss-islington is a bot for PR. 😉
