CVE-2026-113355

A vulnerability has been found in chatwoot up to 4.17.1. This impacts an unknown function of the file callbacks_controller.rb of the component Shopify OAuth. The manipulation leads to server-side request forgery. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used.

Chatwoot before 4.17.0 contains an authorization bypass vulnerability that allows authenticated agent bots to access other accounts by supplying a foreign contact inbox source_id. Attackers can call the conversations create endpoint with another account's source_id to create or retrieve conversations and post messages to that account's contacts.

Chatwoot prior to version 4.9.0 allowed authenticated account administrators to transfer Portals, Automation Rules, Macros, and Twilio Channels to other accounts through the writable account_id parameter. This could break tenant isolation and cause cross-account data exposure, unauthorized configuration changes, or loss of access to transferred resources.

Chatwoot before version 4.16.0 contains an authentication bypass vulnerability in the direct uploads controller that allows unauthenticated attackers to create arbitrary ActiveStorage blobs in any tenant account. Attackers can exploit missing authentication checks to resolve any account and conversation, then obtain signed PUT URLs to write arbitrary data to the application's storage backend.

Chatwoot is a customer engagement suite. From 2.14.0 to before 4.13.0, a Pre-Account Takeover (Pre-ATO) vulnerability existed in Chatwoot's authentication flow. Because email confirmation was not enforced before an account became usable, an attacker could pre-register an email address they did not own and set a password. If the legitimate owner of that email later signed in to Chatwoot using Google OAuth (or another OmniAuth provider), the OAuth flow silently confirmed the existing account without invalidating the attacker's pre-set credentials. The attacker could then continue to log in with the password they had originally chosen and access any data the victim subsequently entered into the dashboard, including PII, API keys, and other sensitive information. This vulnerability is fixed in 4.13.0.

SQL injection vulnerability in Chatwoot versions 2.2.0 through 4.11.2 in conversation and contact filter APIs. An authenticated attacker can inject arbitrary SQL via date or number filter parameters.

In chatwoot up to version 4.11.2, the Webhooks::Trigger function in lib/webhooks/trigger.rb does not validate the url argument, leading to server-side request forgery (SSRF). The attack is remotely exploitable and the exploit is publicly available.

A cross-site scripting (XSS) vulnerability was found in Chatwoot up to 4.7.0 in the Admin Interface component, specifically in app/javascript/shared/components/IframeLoader.vue. Manipulating the Link argument allows script execution, and the attack can be performed remotely.

A vulnerability was identified in Chatwoot up to version 4.7.0 affecting the initPostMessageCommunication function in app/javascript/sdk/IFrameHelper.js of the Widget component. Manipulation of the baseUrl argument leads to an origin validation error. The vendor was contacted but did not respond.
