CVE-2026-49213 baptisteArno CVE debrief

Who should care

Users of TypeBot, especially those with workspace editor or creator roles, should be aware of this vulnerability and take steps to mitigate it by updating to version 3.17.2 or later. Additionally, security teams and platform administrators should review configurations and monitor for suspicious activity related to SSRF attacks.

Technical summary

The vulnerability exists in the shared SSRF validator in packages/lib/src/ssrf/validateHttpReqUrl.ts. The validateIPAddress function blocks local, metadata, and private ranges but does not block :: or its expanded form. This allows for SSRF attacks, potentially leading to unauthorized access to local HTTP services through safeKy, especially in configurations involving server-side HTTP Request blocks or guarded script fetches. A workspace editor or creator can leverage this to make the Typebot server connect to local HTTP services, which could lead to sensitive information disclosure or further exploitation.

Defensive priority

High priority should be given to updating TypeBot to version 3.17.2 or later. Additionally, users should review their configurations for server-side HTTP Request blocks or guarded script fetches and ensure they are not vulnerable to SSRF attacks. Monitoring for suspicious activity and implementing compensating controls are also recommended.

Recommended defensive actions

• Update TypeBot to version 3.17.2 or later
• Review and restrict configurations for server-side HTTP Request blocks or guarded script fetches
• Monitor for suspicious activity related to SSRF attacks
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
