Network-delivered stored XSS requires low-privileged auth (PR:L) and a victim page visit (UI:R); payload executes in another user's session, constituting a scope change (S:C) with limited confidentiality and integrity impact.
Primary rating from Vendor (WatchGuard).

Lifecycle Timeline
2DescriptionCVE.org
A stored cross-site scripting (XSS) vulnerability in WatchGuard Dimension's task scheduling feature allows a low-privileged authenticated administrator to inject arbitrary HTML/JavaScript into these fields, which then executes in the browser session of any other user.
AnalysisAI
Stored XSS in WatchGuard Dimension's task scheduling feature allows a low-privileged authenticated administrator to inject persistent JavaScript into scheduling fields, which silently executes in the browser session of any other user who subsequently views the affected interface. Unlike reflected XSS, the stored nature of this vulnerability means a single injection can compromise multiple sessions without further attacker interaction, including those of higher-privileged administrators. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privileged authenticated administrator account on the target WatchGuard Dimension instance - unauthenticated network access alone is insufficient and cannot trigger this vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.1 (Medium) accurately captures the key constraints: network-accessible delivery (AV:N), low complexity (AC:L), low-privilege authenticated attacker (PR:L), and a passive victim interaction requirement (UI:P), with impact scoped to the subsequent system (SC:L/SI:L/SA:L) rather than direct server compromise. … 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-2026-78047 for the vendor-confirmed patched version, as no specific fixed release has been independently confirmed from available data - citing a version number here would require fabrication. … Detailed patch versions, workarounds, and compensating controls in full report. |
