corvus is vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition
20
Low Risk
This Affects:
corvusTL;DR
Affected versions of this package create the secret key file and then restrict its permissions in a separate step, introducing a TOCTOU race condition. A local attacker could potentially read the secret key during the brief window between file creation and permission restriction. The patch uses OpenOptions with mode(0o600) on Unix to atomically create the file with restrictive permissions.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
