KG-5230TAS-IL-3: Improper Limitation of a Pathname to a Restricted Directory
CVE-2026-7766 is a high-severity improper limitation of a pathname to a restricted directory vulnerability in KG-5230TAS-IL-3 from Kenik, with a CVSS 4.0 base score of 8.3 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version 2025-04-21 as the first without the flaw, so updating KG-5230TAS-IL-3 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.26% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update KG-5230TAS-IL-3 to 2025-04-21 or a later version.
- Update KG-5230TAS-IL-G3 to 2025-04-21 or a later version.
- Update KG-5230DAS-IL-G3 to 2025-04-21 or a later version.

Official description
Kenik Camera management Panel is vulnerable to Path Traversal vulnerability. An unauthenticated attacker can send GET request with arbitrary file path and read corresponding files located on the server. The issue was fixed in version 2026-04-23 of the KG-5260xxxx-IL-(G)2 cameras. Rest of the products were fixed in version 2025-04-21.

The underlying weakness: Improper Limitation of a Pathname to a Restricted Directory
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
How developers prevent this class of flaw
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
