Severity
2.2 (Low) - CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N
Summary
Pi is a minimal terminal coding harness. From 0.74.0 until 0.78.1, Pi stored API keys and OAuth credentials in auth.json. A race condition in the file write path could briefly create or rewrite this file with permissions derived from the process umask before tightening the file to owner-only permissions. This vulnerability is fixed in 0.78.1.
