CVE-2026-44706

Description

The custom attribute definition API allows creating attributes with arbitrary attribute_key values without validation. When these attributes are used in conversation/contact filters, the key is directly interpolated into SQL queries in build_custom_attr_query, enabling stored SQL injection. An attacker can create a malicious custom attribute once, then trigger the injection whenever that attribute is used in a filter.

Pulled from cveawg.mitre.org/api/cve/CVE-2026-44706 on 2026-07-04. Shown when MITRE's text differs from the cvelistV5 mirror.

Chatwoot is a customer engagement suite. From 2.2.0 to before 4.11.2, a SQL injection vulnerability exists in the conversation and contact filter APIs. When filtering by a custom attribute of type date or number using the is_greater_than or is_less_than operators, user-supplied values in the values field of the filter payload are interpolated directly into the SQL query without parameterization. Any authenticated user with access to an account can exploit this to execute arbitrary SQL via time-based blind injection. This affects /api/v1/accounts/{account_id}/conversations/filter, /api/v1/accounts/{account_id}/contacts/filter, and /api/v1/accounts/{account_id}/custom_attribute_definitions. This vulnerability is fixed in 4.11.2.
