{"id":"CVE-2026-106155","published":"2026-10-09T08:16:54.377","lastModified":"2026-10-09T18:17:02.077","description":"In Progress® Telerik® Report Server prior to version 12.2.26.1007, a stored cross-site scripting vulnerability in the shared reporting engine allows an authenticated report author to embed javascript: or vbscript: URLs in report navigation actions or HTML text box links. 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.","cvssScore":8.9,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:L","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://www.telerik.com/report-server/documentation/knowledge-base/kb-security-improper-neutralization-of-input-cve-2026-106155","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"A stored cross-site scripting vulnerability in the shared reporting engine of Progress® Telerik® Report Server prior to version 12.2.26.1007 allows an authenticated report author to inject malicious JavaScript, enabling privilege escalation and execution of attacker-controlled scripts in the context of the victim's session.","exploitability":"Exploitation requires an authenticated user with report author privileges and a target user who views the malicious report. The vulnerability is relatively straightforward to exploit once the attacker has crafted the malicious content.","blast_radius":"If exploited, this vulnerability can lead to full control over the victim's session, potentially enabling the attacker to perform actions with higher privileges, including administrative tasks.","remediation":"Upgrade to Progress® Telerik® Report Server version 12.2.26.1007 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["xss","auth","web","priv-escalation"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-09T08:43:34.983Z"}}
