🟡 Changes recommended
Removing the existing CVSS v3.1 vector leaves only CVSS v4 data, preventing consumers that rely on CVSS v3 from obtaining the advisory’s severity score.

| "details": "A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a \"one-shot\" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the \"streaming\" API as opposed to the \"one-shot\" API, and impose chunk size limits.", | ||

brotlipy was archived on PyPI. Its latest release 0.7.0 bundled the affected Brotli version 0.6.0.
