Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2026-86296 | Stack-based buffer overflow in the D-Link DIR-822A (firmware A_101) router allows attackers to corrupt memory in the udhcpd DHCP server via an unbounded strcpy in serverpacket.c while parsing TR-111 DHCP Option 125. The exploit writeup and VulDB entry are public (publicly available exploit code exists), and successful exploitation can crash the DHCP service or achieve code execution on the device. No confirmed active exploitation (not in CISA KEV), but a working POC lowers the bar for opportunistic use against reachable devices. | CRITICAL | 9.3 | 1.3% | 68 |

| CVE-2026-82691 | OS command injection in D-Link DNS-320L, DNS-327L, DNS-340L, and DNS-345 NAS devices allows remote authenticated attackers to execute arbitrary operating system commands by manipulating the `f_ups_ip` argument passed to `/cgi-bin/usb_device.cgi`. The vulnerability arises from unsanitized user-controlled input being passed directly to an OS shell call (CWE-78) within the CGI handler responsible for USB/UPS device configuration. A public proof-of-concept exploit has been disclosed; no patch has been identified at time of analysis. EPSS data was not provided, but the combination of a network-accessible vector, publicly available exploit, and widespread SMB/home-lab deployment of these NAS models elevates real-world risk. | HIGH | 8.5 | 2.1% | 65 |

| CVE-2026-90699 | OS command injection in D-Link DWR-M920 firmware version 1.1.7 allows a network-adjacent or remote authenticated attacker to execute arbitrary operating system commands by manipulating the newPin parameter submitted to the /boafrm/formPinManageSetup endpoint. The vulnerability resides in the sub_41E60C function, which fails to sanitize user-supplied input before passing it to a system call. A publicly available proof-of-concept exploit exists. No public exploit identified at time of analysis as confirmed by CISA KEV, but exploit code is publicly available per VulDB and the GitHub reference. | HIGH | 8.6 | 1.6% | 65 |

| CVE-2026-82593 | Stack-based buffer overflow in the D-Link DIR-825M 1.1.8 LTE Module Firmware Upgrade handler allows low-privileged remote attackers to achieve remote code execution by supplying an oversized fota_url argument to /boafrm/formLtefotaUpgradeFibocom. The CVSS 4.0 vector scores this at 8.6 with subsequent-system impact (SC:H/SI:H/SA:H), reflecting the potential to compromise the attached Fibocom LTE module as well as the primary router. A public proof-of-concept exploit is available on GitHub, significantly lowering the bar for exploitation; no public patch has been identified at time of analysis. | HIGH | 8.6 | 0.5% | 64 |

| CVE-2026-86510 | Out-of-bounds write in D-Link DIR-822A firmware A_101 allows network-reachable authenticated attackers to corrupt memory and likely achieve remote code execution by sending a crafted L2TP control message with a malformed Host Name AVP to the vulnerable tunnel_set_params function. A public proof-of-concept demonstrating the specific Host Name AVP overflow has been published on Notion, substantially lowering the exploitation barrier. No vendor-released patch has been identified at time of analysis, leaving affected devices exposed without a direct remediation path. | HIGH | 8.6 | 0.5% | 63 |
