CVE-2026-23809: MAC Address Spoofing leads to Inter-BSSID Isolation Bypass Resulting in Traffic Redirection
- Severity: high (CVSS 7.6 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-03-04 · updated 2026-06-17
- Weakness: CWE-400
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.
