A Reflected Cross-Site Scripting (XSS) vulnerability in WatchGuard Dimension's report detail page allows an attacker to execute arbitrary JavaScript in a authenticated user's browser with a specially crafted URL.
AnalysisAI
Reflected XSS in WatchGuard Dimension's report detail page allows arbitrary JavaScript execution in the browser of an authenticated victim when they follow a specially crafted URL. The vulnerability requires social engineering an already-authenticated Dimension user - likely an administrator, given the CVSS 4.0 PR:H rating - into clicking an attacker-controlled link, constraining the attack to targeted phishing scenarios against active sessions. …

Vulnerability AssessmentAI
| Exploitation | The victim must be authenticated to WatchGuard Dimension at the time of exploitation - unauthenticated users reaching the report detail page would not provide a useful attack surface since the CVSS 4.0 PR:H rating indicates high-privilege session context is required for meaningful impact. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 4.6 is modest and reflects realistic constraints: PR:H (high privileges required from the attacker's perspective, likely meaning only high-privilege victims are meaningful targets) and UI:A (active user interaction) substantially limit exploitability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the WatchGuard PSIRT advisory at https://psirt.watchguard.com/CVE-2026-78615 for the vendor-released patch or fixed version; the source intelligence does not supply an exact fix version number so one cannot be cited here. … Detailed patch versions, workarounds, and compensating controls in full report. |
