High CVSS 8
CVE-2026-65937
NVD analysis in progress
In WhatsUp Gold versions released before 2026.0.2, an authenticated attacker can bypass frontend controls and inject persistent script content.
What this means
- Exposure
- Exploitable from the adjacent network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Attacker-supplied script runs in other users’ browsers (cross-site scripting).
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle.
