CVE-2026-23809
By leveraging the relationship between BSSIDs and their associated virtual ports, an attacker could potentially bypass inter-BSSID isolation controls.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A technique has been identified that adapts a known port-stealing method to Wi-Fi environments that use multiple BSSIDs. By leveraging the relationship between BSSIDs and their associated virtual ports, an attacker could potentially bypass inter-BSSID isolation controls. Successful exploitation may enable an attacker to redirect and intercept the victim's network traffic, potentially resulting in eavesdropping, session hijacking, or denial of service.
