Concurrent calls to the get_response() method can exhaust the pool, causing the bot to become unavailable until a manual restart is performed. This is a resource exhaustion flaw (CWE-400) that results in denial of service, disrupting availability for legitimate users.", "risk_and_exploitability": "The CVSS score of 7.5 indicates a medium\u2011high severity level, though the EPSS score of less than 1% suggests a low likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog. Attackers can trigger the denial of service by sending a high volume of requests to the bot\u2019s get_response() endpoint, typically over a network interface that exposes the bot. In practice, the attack vector would be remote, leveraging the bot\u2019s public API or webhooks, assuming the bot is accessible over the internet. Without a publicly documented exploit, a successful attack would require an active user session or the ability to invoke the get_response() method repeatedly."}}}}, "created": "2026-01-20T08:40:28.581677+00:00", "updated": "2026-04-18T05:15:15.972581+00:00", "vendors": ["gunthercox", "gunthercox$PRODUCT$chatterbot"]}
