When another user views the malicious report and the embedded navigation is triggered, attacker-controlled script can execute in the web report viewer's origin. In a multi-user Report Server deployment, this can enable privilege escalation by performing actions in a higher-privilege user's authenticated session, including an administrator's session.","published":"2026-10-09T08:16:54.000Z","lastModified":"2026-10-09T18:17:02.000Z","status":"Deferred","sourceIdentifier":"security@progress.com","cvss":{"version":"3.1","score":8.9,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:L"},"cwe":["CWE-79"],"affected":[],"epss":{"score":0.00199,"percentile":0.09608,"date":"2026-10-26","history":[{"date":"2026-10-09","score":0.00199,"percentile":0.089}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.20%).
