The real name of a username is displayed unescaped when the user is mentioned (using the @ symbol) in a channel or private chat. Consequently, it is possible to exfiltrate the secret token of every user and also admins in the channel.","modified":"2026-08-07T14:54:21.063871Z","published":"2018-07-11T01:29:01.503Z","references":[{"type":"REPORT","url":"https://github.com/RocketChat/Rocket.Chat/pull/10793"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rocketchat/rocket.chat","events":[{"introduced":"0"},{"fixed":"9cd892d0874f65d2f373f71fd130ea486bb482a4"}],"database_specific":{"cpe":"cpe:2.3:a:rocket.chat:rocket.chat:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.65"}],"source":"CPE_RANGE"}}],"versions":["0.64.2","0.64.1","0.64.0","0.63.3","0.63.2","0.63.1","0.63.0","0.62.2","0.62.1","0.62.0","0.61.2","0.61.1","0.61.0","0.60.4","0.60.3","0.60.2","0.60.1","0.60.0","0.59.6","0.59.5","0.59.4","0.59.3","0.59.2","0.59.1","0.59.0","0.58.2","0.58.1","0.58.0","0.57.2","0.57.1","0.57.0","0.56.0","0.56.0-rc.7","0.56.0-rc.6","0.56.0-rc.5","0.56.0-rc.4","0.56.0-rc.3","0.56.0-rc.2","0.56.0-rc.1","0.56.0-rc.0","0.54.1","0.54.0","0.50.0","0.49.4","0.49.3","0.49.2","0.49.1","0.49.0","0.48.0","0.46.0","0.45.0","0.44.0","0.43.0","0.42.0","0.41.0","0.40.1","0.40.0","0.39.0","0.38.0","0.37.1","0.37.0","0.36.0","0.30.0","0.29.0","0.28.0","0.27.0","0.26.0","0.25.0","0.24.0","0.23.0","0.19.0","0.18.0","0.17.0","0.16.0","0.15.0","0.14.0","0.13.0","0.11.0","0.10.2","0.10.1","0.10.0","0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-13878.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
