CVE-2026-9037 CRITICAL Act Now

Unauthorized firmware installation in the XCharge C6 charging controller stems from missing cryptographic signature verification in its management-channel update mechanism, enabling remote attackers who can interpose on or impersonate the management interface to push malicious firmware. Successful exploitation yields high-privilege code execution on the EV charging device, and the issue is tracked in CISA ICS advisory ICSA-26-148-08 with no public exploit identified at time of analysis.

CVE-2026-9089 HIGH This Week

Code integrity failure in ConnectWise Automate Agent versions prior to 2026.5 allows adjacent network attackers to substitute malicious components during plugin loading and self-update operations. The Automate agent does not fully verify the authenticity of downloaded components, enabling code execution at the agent's privilege level across managed endpoints. No public exploit identified at time of analysis, though the high CVSS score of 8.8 and the agent's deep system access make this a priority remediation for MSPs using the platform.

CVE-2026-42249 HIGH This Week

Ollama for Windows contains a Remote Code Execution vulnerability in its update mechanism due to improper handling of attacker‑controlled HTTP response headers. When downloading updates, the application constructs local file paths using values derived from HTTP headers without validation. These values are passed directly to filepath.Join, allowing path traversal sequences (../) to be resolved and enabling files to be written outside the intended update staging directory. An attacker who can influence update responses can exploit this flaw to write arbitrary executables to attacker‑chosen locations accessible to the current user, including the Windows Startup directory. This allows execution of arbitrary executables. Critically, when chained with CVE‑2026‑42248 (Missing Signature Verification for Updates), an attacker can deliver malicious payloads that are written to sensitive locations and executed automatically. Because Ollama for Windows performs silent automatic updates and executes staged binaries without user interaction, this results in automatic and persistent code execution without user awareness. Maintainers of this project were notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Versions from 0.12.10 to 0.17.5 were tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

CVE-2026-42248 HIGH This Week

Ollama for Windows does not perform integrity or authenticity verification of downloaded update executables. Unlike other platforms, the Windows implementation of the update verification routine unconditionally returns success so no digital signature or trust validation is performed before staging or executing update payloads, enabling attacker‑supplied executables to be accepted and later executed by the application. Critically, Ollama for Windows performs silent automatic updates, so the malicious payload may be installed automatically without user awareness. Maintainers of this project were notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Versions from 0.12.10 to 0.17.5 were tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

CVE-2026-40066 HIGH CISA Act Now

Remote code execution in Anviz CX2 Lite and CX7 access control devices allows authenticated attackers to upload malicious firmware update packages that execute arbitrary scripts without verification. Reported by ICS-CERT, targeting physical access control systems commonly deployed in enterprise and critical infrastructure environments. CVSS 8.8 indicates high impact across confidentiality, integrity, and availability once low-privilege authentication is obtained. No public exploit confirmed at time of analysis, but the attack vector is straightforward for authenticated users.

CVE-2026-3428 MEDIUM This Month

Privilege escalation in ASUS Member Center (华硕大厅) versions 1.6.6.4 and earlier allows authenticated local users to achieve Administrator-level privilege escalation by exploiting a Time-of-check Time-of-use (TOC-TOU) race condition during the update process. An attacker can substitute a malicious payload for the legitimate downloaded update immediately after integrity verification completes but before execution, causing the compromised code to run with administrative privileges upon user consent. CVSS 5.4 reflects the requirement for local access, user interaction, and elevated (but non-Administrator) initial privileges; however, the vulnerability achieves full privilege escalation to Administrator with moderate technical difficulty.

Arbitrary code execution in TrueConf Client allows authenticated attackers on adjacent networks to deliver malicious updates due to missing integrity verification. The auto-update mechanism accepts unsigned or unverified payloads, enabling man-in-the-middle attackers with high privileges to substitute trojanized updates that execute with the application's permissions. EPSS data not available; no confirmed active exploitation (not in CISA KEV); publicly available exploit code not identified at time of analysis. CVSS 7.8 reflects the adjacent network attack vector and user interaction requirement, reducing immediate internet-scale risk.

FastGPT versions 4.14.8.3 and below contain a critical arbitrary code execution vulnerability in the fastgpt-preview-image.yml GitHub Actions workflow that allows external contributors to execute malicious code and exfiltrate repository secrets. The vulnerability stems from unsafe use of pull_request_target with attacker-controlled Dockerfile builds that are pushed to the production container registry, enabling both direct compromise and supply chain attacks. No patch was available at the time of public disclosure, making this an unpatched remote code execution affecting the AI Agent building platform across affected versions.
