Browser script execution via unsanitized Vue HTML
Published Apr 21, 2022 · Updated Aug 2, 2024
Stored XSS in Chatwoot before 2.5.0 allows remote attackers to execute script in a user's browser through crafted stored content. Several Vue components render messages, notes, custom attributes, and other HTML through v-html without sanitization; the patch replaces those sinks with v-dompurify-html. Execution requires a user to view attacker-controlled content and can read or modify data available to that browser session.
