This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with custom-level access and above, to access the full message transcript, thread metadata, and user data of any chat-room thread without authentication. This is only exploitable when the chat room's only_joined_can_read setting retains its default value of '0'."}],"title":"Better Messages <= 2.15.33 - Missing Authorization to Authenticated (Custom+) Chat-Room Transcript Disclosure via '/thread/<id>' REST Endpoint","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b3243fe4-9d11-49f0-884b-0162cd776993?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/rest-api.php#L2598"},{"url":"https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/rest-api.php#L181"},{"url":"https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/rest-api.php#L418"},{"url":"https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/functions.php#L3533"},{"url":"https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/functions.php#L3582"},{"url":"https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/functions.php#L3601"},{"url":"https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/rest-api.php#L1964"},{"url":"https://plugins.trac.wordpress.org/changeset?old_path=bp-better-messages%2Ftags%2F2.15.33%2Finc%2Ffunctions.php&new_path=bp-better-messages%2Ftags%2F3.0.0%2Finc%2Ffunctions.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Supakiad S.
