Description
Nitro is a next generation server toolkit. Prior to 3.0.260429-beta, an attacker could bypass a proxy route rule by sending percent-encoded path traversal (..%2f) in the URL, causing Nitro to forward a request that the upstream resolved outside the configured scope. This vulnerability is fixed in 3.0.260429-beta.
Affected configurations
• nitro nitro (< 2.13.4)
• nitro nitro (> 2.13.4 < 3.0.260429)
