High CVSS 7.7

CVE-2026-61390

There is a heap buffer overflow vulnerability in some Hikvision cameras, which may allow unauthenticated attackers to cause device malfunction by sending specially crafted packets.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
Impact
An attacker can read some data, modify or destroy data and take the service offline.
Weakness
A heap overflow corrupts allocator structures and can lead to code execution.
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.
