CVE-2026-38426 HIGH This Week

Remote code execution in Tasmota firmware (v15.3.0.3 and all earlier releases) stems from an unbounded strcpy() into the fixed 40-byte jpg_task.boundary[40] buffer inside fetch_jpg() in the Scripter driver (xdrv_10_scripter.ino). A network attacker able to reach the device and trigger this code path can overflow the buffer and, per the vendor description, execute arbitrary code on the ESP-based device. Publicly available exploit code exists (a CVE-named GitHub repository), and CISA's SSVC framework rates exploitation as POC with the attack automatable; no active exploitation is confirmed.

CVE-2025-12686 CRITICAL PATCH Act Now

Remote code execution in Synology BeeStation OS versions before 1.3.2-65648 stems from a classic buffer overflow in the AdminCenter component, the device's web-based management interface. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates a network-reachable flaw exploitable by unauthenticated attackers with low complexity and no user interaction, yielding full compromise of confidentiality, integrity, and availability (9.8 Critical). There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but the unauthenticated network-RCE profile on a consumer NAS device makes this a high-priority patch target.

CVE-2026-48696 MEDIUM This Month

Buffer overflow in FastNetMon Community Edition through 1.2.9 allows a local attacker with no privileges to crash the FastNetMon process, disabling DDoS detection and network monitoring capabilities. The vulnerability is specifically tied to a sprintf-based overflow in the ExaBGP integration component, as documented in the Lorikeetsecurity advisory. This is one of at least three distinct buffer overflow vulnerabilities (alongside CVE-2026-48686 and CVE-2026-48689) identified in the same product version, suggesting a broader audit surfaced a class of unsafe string-handling bugs. No public exploit identified at time of analysis, and the impact is limited to availability (denial of service) with no confidentiality or integrity exposure.

CVE-2026-9360 HIGH POC This Week

Buffer overflow in Edimax EW-7438RPn Wi-Fi range extender firmware 1.28a enables authenticated remote attackers to execute arbitrary code via malformed POST requests to the wireless encryption configuration endpoint. The vulnerability requires low-privilege authentication and has publicly available exploit code. No vendor response or patch has been provided despite early disclosure attempts.

CVE-2026-9295 HIGH POC This Week

Buffer overflow in the Edimax BR-6428NS 1.10 router's web management interface allows authenticated remote attackers to corrupt memory by submitting a crafted vapurl parameter to the formWirelessTbl POST handler at /goform/formWirelessTbl. Publicly available exploit code exists (released via VulDB and a Notion writeup), and the vendor has not responded to coordinated disclosure attempts. The flaw is not currently listed in CISA KEV, but the combination of public PoC, low attack complexity, and an unpatched/unresponsive vendor makes this a tangible risk for any exposed device.

Stack buffer overflow in the Edimax BR-6428NS 1.10 wireless router allows authenticated remote attackers to corrupt memory by sending an overlong pppUserName parameter to the /goform/formWanTcpipSetup endpoint. Publicly available exploit code exists, and the vendor failed to respond to the coordinated disclosure attempt, leaving devices without an official fix. With a CVSS of 8.8 and full CIA impact, successful exploitation can result in arbitrary code execution or device takeover on the embedded router.
