Weaknesses
CWE-400

Description

The CSP report endpoint in MISP intended to limit logged CSP reports to 1 KB but incorrectly allowed reports up to 1 MB before truncation. On deployments where the endpoint is reachable by untrusted clients, this could allow attackers to generate excessive log volume and contribute to resource exhaustion or log flooding.

Affected configurations

• misp-project misp (>= 2.5.0 < 2.5.38)
