Findings overview

29 total findings

Likely real: 2
Uncertain: 1
Likely noise: 26

The risk classifier rates every finding for how likely it is to be a real issue. Likely noise still counts, just much less.

What we found, in plain English

2 findings likely need attention, 26 look like noise. Most notable: Detected SHA1 hash algorithm which is considered insecure. SHA1 is not collision resist... in /src/requests/auth.py (52% confidence).

Likely real
Yes, 52% confidence

Detected SHA1 hash algorithm which is considered insecure. SHA1 is not collision resistant and is therefore not suitable as a cryptographic signature. Use SHA256 or SHA3 instead.
