CVE-2026-74233 CRITICAL POC Act Now

Remote unauthenticated command execution affects a broad range of Zbtlink MT7620-based routers and gateways (WE1326, WE2426-C, WE5926 family, WE826 family, WG108/WG3526, WF3526-P, CTN720-W1, LF-1541, MT7620N, WRC1) whose infosrvd service listens on UDP/9992. A single crafted UDP packet lets an attacker run arbitrary commands as root, because the service's authentication relies on a hardcoded salt and accepts an all-zero wildcard MAC, defeating the intended check. Publicly available exploit code exists (research and advisory published by VulnCheck), the CVSS 4.0 base score is 9.3, and no active exploitation has been confirmed in CISA KEV at time of analysis.

NVIDIA Unified Fabric Manager Enterprise session management embeds a hard-coded cryptographic key (CWE-321), enabling a local attacker to extract session material and potentially escalate privileges within the InfiniBand fabric management plane. All four active UFM Enterprise release tracks - GA, LTS 2023, LTS 2024, and LTS 2025 - are confirmed affected per CPE data published by NVIDIA. No public exploit code or CISA KEV listing has been identified at time of analysis; EPSS data is absent from available intelligence, limiting probabilistic exploitation forecasting.

CVE-2026-15469 HIGH PATCH This Week

Hard-coded RSA-512 mesh group private key in TP-Link Deco XE75 v3, XE5300 v3.6, and WE10800 v3.6 firmware allows an adjacent attacker to impersonate a trusted mesh node without possessing any device-specific credential. Because the same private key is shared across all affected devices and embedded in firmware images that TP-Link publishes publicly on its download portal, the barrier to key extraction is low. No public exploit or active exploitation has been identified at time of analysis, but a vendor-released patch is available.

CVE-2026-76258 MEDIUM PATCH This Month

Splunk Secure Gateway's companion app registration handler contains a hard-coded cryptographic key, enabling any low-privileged authenticated Splunk user - explicitly excluding admin or power roles - to register an arbitrary attacker-controlled callback URL and cause Secure Gateway to forward mobile user requests and authentication tokens to that URL. Affected are Splunk Enterprise branches 9.4 (below 9.4.14), 10.0 (below 10.0.9), 10.2 (below 10.2.6), and 10.4 (below 10.4.2), alongside Splunk Secure Gateway branches 3.8 (below 3.8.71), 3.9 (below 3.9.24), and 3.10 (below 3.10.10). No public exploit code or active exploitation has been confirmed at time of analysis; however, the low attack complexity and minimal privilege requirement make this a credible insider-threat or post-compromise lateral movement vector in any environment running Splunk Mobile.

CVE-2026-51977 CRITICAL Act Now

Privilege escalation in the Trueview T18061 WiFi 3MP Robot Pan-Tilt Security Camera (firmware Version 1.0) stems from an embedded RSA private key, letting a nearby attacker who recovers or reuses that key gain elevated access to the device. The flaw is classified under CWE-321 (use of a hard-coded cryptographic key), meaning every unit of this model likely shares the same secret key material. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV; EPSS data was not provided.

CVE-2026-64887 HIGH PATCH CISA This Week

Hard-coded cryptographic key exposure in Johnson Controls Airwall before version 4.1 enables local attackers to conduct cryptanalytic attacks against the product's cryptographic protections. Because the same key material is embedded across all product instances, reverse engineering one installation yields a key applicable to all deployments. No public exploitation has been identified (SSVC: Exploitation none), and the vendor has confirmed a patch is available in version 4.1, limiting the urgency window. The CVSS 4.0 score of 7.0 reflects high confidentiality impact with low integrity exposure, constrained by a local attack vector.

CVE-2026-17468 MEDIUM PATCH This Month

Session token forgery is possible in IBM Documentation Offline versions 1.0.0 through 1.4.1 because the application uses a hardcoded cryptographic key to generate or validate session tokens. An unauthenticated remote attacker who recovers the embedded key - via binary analysis, decompilation, or source exposure - can craft arbitrary valid session tokens and impersonate any authenticated user without supplying credentials. IBM has released a patch (advisory 7283484); no public exploit or CISA KEV listing has been identified at time of analysis.

Privilege escalation in Lenovo Accessories and Display Manager for Enterprise for Windows allows a local authenticated user with low-level privileges to execute arbitrary code at elevated privilege levels, stemming from a hard-coded cryptographic key (CWE-321). The vulnerability was surfaced during an internal Lenovo security assessment and affects all versions of the product per the CPE wildcard. No public exploit code or CISA KEV listing is identified at time of analysis; a vendor patch is confirmed available via Lenovo advisory LEN-213038.

CVE-2026-34635 HIGH This Week

Hard-coded cryptographic key in Adobe ColdFusion 2023 and 2025 enables a local low-privileged attacker to bypass security controls and gain unauthorized read and write access with scope change to components beyond the vulnerable server. The CVSS vector (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H) confirms local access with minimal complexity is sufficient - no user interaction is needed. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the deterministic, non-rotating nature of a hard-coded key means any attacker who extracts it retains persistent capability until the key is replaced via patch.

Hardcoded AES encryption in Siemens LOGO! Soft Comfort (all versions before V9) exposes every password-protected project file to decryption without knowledge of any user-defined password. A local attacker who can access the application installation - via shared workstation access, insider position, or post-compromise foothold - can extract the static master key from binaries or process memory and apply it universally to any project file ever encrypted by the affected software. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
