High CVSS 8.2
CVE-2026-58525
Improper access control in Microsoft Edge (Chromium-based) allows an unauthorized attacker to bypass a security feature over a network.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data and alter some data. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- Access control is applied incorrectly, leaving a protected resource reachable without the required rights.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
