Description
The public dashboard query endpoint does not limit request body size before processing, allowing unauthenticated attackers to trigger excessive memory allocation by sending arbitrarily large JSON payloads. This can lead to denial of service through memory exhaustion. No valid dashboard access token or authentication is required to exploit this vulnerability.
Faiblesses (CWE)
- CWE-400 — Consommation de ressources non maîtrisée (déni de service)
- CWE-770 — Allocation de ressources sans limite ni régulation
