WatchGuard PSIRT Advisories via NVD
WatchGuard is not its own NVD CNA and its PSIRT portal has no machine-readable feed, so VulniPulse ingests WatchGuard's CVEs from NVD (keyword-filtered to WatchGuard, requiring a WatchGuard product in the description) and links each CVE back to the wgrd-psirt advisory when referenced. Covers Fireware OS on the Firebox firewall line, WatchGuard System Manager, the WatchGuard Agent / EPDR endpoint and AuthPoint MFA — SMB firewalls previously mass-exploited by the Cyclops Blink botnet, so a patch-now audience.

A Cross-Site Scripting (XSS) vulnerability in the WatchGuard Dimension Backup Historical Data feature allows an authenticated administrator user to execute arbitrary JavaScript in another user's browser.
Medium [CVE-2026-78103] WatchGuard Dimension provides a client-side lock/unlock UI control for management changes
WatchGuard Dimension provides a client-side lock/unlock UI control for management changes. The server-side configuration endpoint does not enforce this lock/unlock workflow state, allowing an authenticated administrator to submit configuration changes directly to the endpoint without first completing the UI unlock step. This allows an authenticated read-write administrator session to bypass the intended editing workflow and overwrite configuration changes being made by another concurrent administrator session.
Medium [CVE-2026-78615] 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
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.

A server-side request forgery (SSRF) vulnerability WatchGuard Dimension Remote Backup Connection Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems.
Medium [CVE-2026-78617] WatchGuard Dimension's web login endpoint does not enforce effective rate-limiting or account lockout by default allowing a remote attacker to perform automated password guessing against user accounts
WatchGuard Dimension's web login endpoint does not enforce effective rate-limiting or account lockout by default allowing a remote attacker to perform automated password guessing against user accounts. If the account lockout setting is enabled, brute-force attempts are blocked after a defined number of failed attempts, but this setting is not enabled by default.
Medium [CVE-2026-78047] 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
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.
Medium [CVE-2026-78499] server-side request forgery (SSRF) vulnerability WatchGuard Dimension FTP Server Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems
A server-side request forgery (SSRF) vulnerability WatchGuard Dimension FTP Server Test configuration allows an authenticated privileged attacker to enumerate exposed network services on adjacent network systems.
