This absence of rate limiting may allow an attacker to conduct denial-of-service attacks or brute-force attacks to gain unauthorized access.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-307"],"vendors":[],"products":[],"references":[{"url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-274-02.json","tags":[]},{"url":"https://www.cisa.gov/news-events/ics-advisories/icsa-26-274-02","tags":[]}],"exploitRefs":[{"url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-274-02.json","tags":[]}],"hasPoc":true,"ai":{"summary":"The WebSocket API lacks rate limiting on authentication requests, allowing attackers to perform denial-of-service attacks or brute-force credential guessing with unlimited attempts. This vulnerability exists due to insufficient input validation and control over authentication request frequency.","exploitability":"Exploitation is straightforward requiring only a WebSocket connection and ability to send repeated authentication messages, with no special preconditions needed beyond network access to the affected service.","blast_radius":"An attacker could exhaust system resources through massive concurrent authentication attempts or successfully brute-force credentials across many accounts, potentially leading to unauthorized access to user sessions or complete service disruption.","remediation":"Implement rate limiting on WebSocket authentication endpoints with a maximum of 10 requests per minute per IP address, and consider adding exponential backoff for failed attempts.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["websocket","dos","brute-force"],"model":"garnet-coder","analyzedAt":"2026-10-12T09:02:18.179Z"}}
