CVE-2026-42127
Last modified
CVE-2026-42127 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
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.
