CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-7256 Command injection in Zyxel WRE6505 v2 firmware V1.00(ABDV.3)C0 allows unauthenticated adjacent network attackers to execute arbitrary operating system commands via crafted HTTP requests to the CGI interface. This vulnerability affects an end-of-life product with no vendor support, meaning no security patches will be released. Exploitation requires adjacent network access (same LAN segment) but no authentication, making it exploitable by any device on the local network including compromised IoT devices or malicious insiders. HIGH 8.8 0.8% 45
No patch
CVE-2026-7287 Remote unauthenticated attackers can crash Zyxel NWA1100-N access points running customized firmware version 1.00(AACE.1)C0 by sending malformed HTTP requests that trigger buffer overflows in five distinct web server functions (formWep, formWlAc, formPasswordSetup, formUpgradeCert, formDelcert). The vulnerability enables denial-of-service attacks with high CVSS 7.5 severity but is limited to an end-of-life product according to Zyxel's reference documentation. No public exploit code identified at time of analysis, and EPSS data is unavailable for this recent CVE. HIGH 7.5 0.3% 38
No patch
CVE-2026-7255 Brute-force password attacks against the web management interface of Zyxel WRE6505 v2 firmware V1.00(ABDV.3)C0 succeed due to improper rate-limiting on authentication attempts, allowing adjacent LAN attackers to bypass authentication and gain administrative access without requiring valid credentials. The vulnerability affects a legacy wireless range extender model marked as end-of-life by Zyxel, with CVSS 6.5 reflecting high confidentiality impact but local network scope. MEDIUM 6.5 0.0% 33
No patch
CVE-2026-7257 Zyxel WRE6505 v2 firmware stores sensitive configuration data in an insecure manner, allowing local administrators to download and decrypt backup configuration files, leading to disclosure of confidential credentials and network settings. The vulnerability affects firmware version V1.00(ABDV.3)C0 and requires local access with administrative privileges. No public exploit code or active exploitation has been identified; however, the product is no longer supported by Zyxel, limiting patch availability. MEDIUM 4.4 0.0% 22
