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'.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/functions.php#L3533","https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/functions.php#L3582","https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/functions.php#L3601","https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/rest-api.php#L181","https://plugins.trac.wordpress.org/browser/bp-better-messages/tags/2.15.33/inc/rest-api.php#L1964"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-89334","score":0.00697,"percentile":0.53093,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
