Due to improper sanitization of user input, HTTPEngine.Handle allows for directory traversal, allowing an attacker to read files outside of the target directory that the server has permission to read.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
