CVE-2026-49278
Published:June 24, 2026
Updated:June 29, 2026
Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.6, 7.13.8, and 7.10.12, in the visitors.info endpoint, https://developer.rocket.chat/apidocs/get-visitor-information-by-id-1, token is returned in the response. It looks like there's no use case for the token to be present in the response and it would be a good security practice to remove it altogether. This vulnerability is fixed in 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.6, 7.13.8, and 7.10.12.
