Oct 2026: Microsoft Edge (Chromium-based) Security Feature Bypass Vulnerability
CVE-2026-96196 Published on October 29, 2026

What is a Denylist / Deny List Vulnerability?

The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete, leading to resultant weaknesses. Developers often try to protect their products against malicious input by performing tests against inputs that are known to be bad, such as special characters that can invoke new commands. However, such lists often only account for the most well-known bad inputs. Attackers may be able to find other malicious inputs that were not expected by the developer, allowing them to bypass the intended protection mechanism.

CVE-2026-96196 has been classified to as a Denylist / Deny List vulnerability or weakness.
