AnalysisAI

We need to produce a JSON object according to the detailed instructions. The CVE is CVE-2026-18084, BlackBerry UEM Management Console, XSS, CVSS 4.0 given, CVSS 3.1 not provided, we need to independently assess CVSS 3.1 and 4.0 vectors, prevalence, etc.

First, extract from input:

  • product_name: "BlackBerry UEM" (precisely "UEM" or "BlackBerry UEM Management Console" but description says "BlackBerry UEM Management Console of BlackBerry UEM" so product is BlackBerry UEM, specific component Management Console). We need 1-3 words, so "BlackBerry UEM" is fine.
  • summary: must synthesize from multiple sources. Description: Improper Neutralization of Input During Web Page Generation vulnerability in BlackBerry UEM Management Console allows Cross-Site Scripting (XSS). Affects UEM: 12.23.0 QF8 or earlier. CVSS 4.0: 8.6, vector AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:L/SI:L/SA:N. CWE-79. Tags: XSS, Uem. Reported by blackberry. CPE: cpe:2.3:a:blackberry:uem:*:*:*:*:*:*:*:* References: https://support.blackberry.com/pkb/s/article/141208. No KEV, POC status unknown. So we need to write summary: start with specific impact and product. "Cross-site scripting in BlackBerry UEM Management Console (versions 12.23.0 QF8 and earlier) allows..." Actually, XSS impact: an attacker can inject malicious scripts into the web console that execute in users' browsers. Potential impact: stealing session cookies, performing actions as victim, etc. But the CVSS 4.0 VC:H/VI:H/VA:H suggests high impact to vulnerable system (confidentiality, integrity, availability), and SC:L/SI:L suggests low subsequent impact. So it's a stored or reflected XSS with high impact on management console itself. So summary: "Cross-site scripting in BlackBerry UEM Management Console (versions 12.23.0 QF8 and earlier) allows an unauthenticated attacker to inject malicious scripts via crafted input, potentially leading to unauthorized actions, data theft, or system compromise on the UEM server." Need to mention 'activel
