CVE-2026-5205 Details
Description
A vulnerability was identified in chatwoot up to 4.11.2. Affected by this vulnerability is the function Webhooks::Trigger in the library lib/webhooks/trigger.rb of the component Webhook API. Such manipulation of the argument url leads to server-side request forgery. The attack can be launched remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
A server-side request forgery (SSRF) vulnerability has been identified in Chatwoot versions prior to 4.11.2. The issue arises in the Webhook API, specifically within the Webhooks::Trigger function in the lib/webhooks/trigger.rb file. The vulnerability allows users with the appropriate roles to create webhooks that POST to user-defined URLs. While the Webhook model validates the URL format, it does not restrict URLs pointing to internal or private IP addresses. This lack of validation enables the Chatwoot server to be manipulated into sending requests to internal services, potentially leading to unauthorized access or data exposure.
It is recommended to validate webhook URLs against private IP ranges before saving or executing them. Additionally, using an SSRF-safe HTTP client in the Webhooks::Trigger class can help mitigate the vulnerability. Applying the same protections to automation rule and macro webhook actions is also advised.
