CVE-2026-32983 PUBLISHED

SSL/TLS Renegotiation DoS in Wazuh Manager authd service

Assigner: VulnCheck
Reserved: 17.03.2026 Published: 27.03.2026 Updated: 27.03.2026

Wazuh Manager authd service in wazuh-manager packages through version 4.7.3 contains an improper restriction of client-initiated SSL/TLS renegotiation vulnerability that allows remote attackers to cause a denial of service by sending excessive renegotiation requests. Attackers can exploit the lack of renegotiation limits to consume CPU resources and render the authd service unavailable.

Impacts

The Wazuh Manager authd service does not properly restrict client-initiated SSL/TLS renegotiation, which may allow remote attackers to cause a denial of service through CPU consumption by performing repeated renegotiations within a single connection.
