High CVSS 8.2

CVE-2026-50528

Microsoft .net

Incorrect authorization in .NET allows an unauthorized attacker to bypass a security feature over a network.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim.
Impact
An attacker can read some data and modify or destroy data.
Weakness
An authorisation check exists but its logic is wrong.
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. Start with the instances exposed to the internet.
