From a standard user account an attacker can write to PS/2 controller, CPU reset, CMOS configuration, and interrupt controller ports, triggering an immediate forced system reset or persistent hardware-level manipulation. A public technical disclosure repository (github.com/floppywiggler/directio64-disclosure) and accompanying blog post exist; no CISA KEV listing is present and no EPSS score was provided.
Buffer overread in OpenVPN's Windows service component (`openvpnserv`) through version 2.7.6 exposes adjacent service process memory or crashes the service when NRPT domain entries containing Internationalized Domain Names (IDN) with UTF-8 encoding trigger an incorrect buffer size calculation (CWE-131). The flaw is Windows-specific and confined to split-DNS configurations that include non-ASCII domain names; Linux and macOS deployments are unaffected. The issue was discovered by BreachX Zero Day Labs and fixed in OpenVPN v2.7.7, co-released with four other security patches. No public exploit code or CISA KEV listing has been identified at time of analysis.
sbt on Windows is vulnerable to command injection through unvalidated URI fragments in VCS dependency declarations. When resolving git, mercurial, or subversion repositories, sbt passes user-controlled branch, tag, or revision parameters directly to cmd.exe without sanitization, allowing attackers to inject arbitrary Windows commands via special characters like &, |, and ; that cmd /c interprets as command separators. An attacker who controls a dependency URI in a project's build.sbt file can execute arbitrary commands with the privileges of the user running sbt. A proof-of-concept exists demonstrating execution of calc.exe, and patches are available from the vendor for sbt versions 1.12.7 and later.
OpenClaw versions 2026.2.26 through 2026.3.0 contain a current working directory (CWD) injection vulnerability in the Windows wrapper resolution mechanism for .cmd and .bat files, allowing attackers with local access to manipulate CWD and achieve command execution with integrity compromise. An attacker with local privileges can alter the working directory to inject malicious wrapper scripts that execute instead of legitimate ones, bypassing command execution controls. The vulnerability requires local access and moderate complexity but enables high-integrity impact; no active KEV or widespread exploitation has been reported, but proof-of-concept details are documented in vendor security advisories.
A time-based one-time password (TOTP) reuse vulnerability exists in Vikunja's authentication implementation where a valid TOTP code can be used multiple times within its 30-second validity window, allowing an attacker who captures or obtains a valid code to authenticate as a targeted user. This affects all users who have enabled two-factor authentication (2FA) on Vikunja instances, and while the CVSS score of 5.7 reflects moderate severity, the vulnerability undermines a critical layer of the defense-in-depth authentication model. A proof-of-concept demonstrating the reuse attack has been publicly disclosed.
Cryptomator versions 1.6.0 through 1.19.0 contain a path traversal vulnerability in vault configuration parsing where the masterkeyfile loader resolves an unverified keyId parameter as a filesystem path before integrity checks are performed. An attacker with the ability to supply a malicious vault configuration can exploit this to trigger arbitrary file existence checks, including UNC paths on Windows that can initiate outbound SMB connections before the user even enters a passphrase, potentially leading to information disclosure about local file structure and network exposure. The vulnerability has been patched in version 1.19.1, and while no active KEV exploitation has been reported, the low attack complexity and the ability to chain this with social engineering (malicious vault sharing) makes it a moderate practical risk.
Greenshot versions 1.3.312 and earlier contain an untrusted executable search path vulnerability (CWE-426) that allows local attackers with high privileges to achieve arbitrary code execution by hijacking the explorer.exe binary launch. When a user double-clicks the Greenshot tray icon to open the screenshot directory, the application launches explorer.exe using a relative path rather than an absolute path, enabling an attacker to plant a malicious executable in a prioritized search location. This vulnerability had no patch available at the time of publication and represents a real privilege escalation and code execution risk requiring immediate user action.
Command injection in OpenClaw versions before 2026.2.19 allows local attackers with limited privileges to execute arbitrary commands when the Lobster extension tool falls back to Windows shell execution after subprocess failures. The vulnerability exists because the tool uses shell: true after spawn errors, enabling attackers to inject shell metacharacters into command arguments. A patch is available for affected users.
OpenClaw versions prior to 2026.3.1 contain a current working directory (cwd) injection vulnerability in Windows wrapper resolution for .cmd/.bat files that allows local attackers to manipulate command execution through directory control during shell fallback mechanisms. An authenticated local attacker with low privileges can exploit this vulnerability to achieve command execution integrity loss by controlling the working directory, potentially leading to unauthorized code execution or privilege escalation. While no active in-the-wild exploitation has been reported in KEV databases, the vulnerability is documented with a proof-of-concept available through the vendor's security advisory on GitHub.
OpenClaw versions prior to 2026.2.19 allow local attackers with limited privileges to execute arbitrary commands through the Lobster extension's Windows shell fallback mechanism by injecting malicious arguments into workflow processes. The vulnerability exploits cmd.exe command interpretation when spawn operations fail and trigger shell execution, enabling command injection with potential impact on system integrity and availability. A patch is available for affected versions.
OpenClaw versions before 2026.2.19 allow local authenticated users to execute arbitrary commands by injecting shell metacharacters into environment variable values during Windows Scheduled Task script generation. The vulnerability stems from unquoted variable assignments in gateway.cmd that fail to sanitize special characters like &, |, ^, %, and !, enabling command injection when the task script runs. A patch is available to address this local privilege escalation risk.
OpenClaw versions prior to 2026.2.21 contain an approval-integrity mismatch vulnerability in the system.run function that allows authenticated operators to execute arbitrary commands on Windows systems by appending malicious arguments after cmd.exe /c while the approval audit log records only the benign command text. An authenticated attacker with operator privileges can exploit this to achieve local command execution on trusted Windows nodes with mismatched or incomplete audit trails, enabling information disclosure and lateral movement while evading detection.
