Research direction

Start with advisories/python/PSF-2023-2.json and compare its fixed-version data with the linked CPython backport commit and the NVD entry for CVE-2023-27043. Check whether other advisory files have the same omission; the work is done when the relevant backported fixes are accurately represented in the advisory data.

Written by the indexing model from the issue text.

Description

The issue first showed up for PSF-2023-2 aka CVE-2023-27043 for me, but I suspect it may affect many more issues. For brevity I'll focus on this one.

The advisory data says it is fixed in https://github.com/python/cpython/commit/4a153a1d3b18803a684cd1bcc2cdf3ede3dbae19, i.e. 3.13.0. From looking around I can find e.g. https://github.com/python/cpython/commit/ee953f2b8fc12ee9b8209ab60a2f06c603e5a624, which fixes the same thing in 3.9.20. This information is sadly not reflected in the above advisory file.

Even the NVD database meanwhile has versions for this one that look reasonable to me: https://nvd.nist.gov/vuln/detail/CVE-2023-27043
