CVE-2026-44706Network attack vector

Cross-tenant data disclosure via filter SQL injection

Published May 26, 2026 · Updated May 26, 2026

SQL injection in Chatwoot 2.2.0 through 4.11.1 allows remote authenticated users to read cross-tenant data through filter APIs. Filter builders interpolate date or number values directly into SQL and embed unchecked custom-attribute keys in JSON path expressions without bind parameters. Account access is required; time-based blind queries disclose emails, password hashes, API tokens, conversation content, contact PII, and integration credentials, but stacked writes are unavailable.
