CVE-2026-7629: Low Vulnerability in kleneway awesome-cursor-mpc-server

CVE-2026-7629 is a low-severity command injection vulnerability found in kleneway awesome-cursor-mpc-server up to version 2.0.1. The flaw exists in the function runCodeReviewTool located in the file src/tools/codeReview.ts of the component Ccode-Review Tool. This vulnerability allows attackers to execute arbitrary commands by manipulating inputs to this function. The attack can be launched remotely, increasing its potential impact. The exploit has been published and may be used, underscoring the urgency of addressing this vulnerability.

With a CVSS score of 2.1, the severity of this vulnerability is classified as low. However, organizations should not underestimate its risk. The potential for remote exploitation means that unpatched systems could become targets for attackers, resulting in unauthorized access or system compromise. While the project maintainers were informed of this issue through a pull request, they have yet to respond, leaving a window for exploitation.

Organizations should prioritize patching immediately. As the landscape of vulnerabilities continues to evolve, timely remediation is crucial to safeguarding systems against potential exploitation.

The urgency to patch this vulnerability is underscored by the fact that it has been publicly disclosed, making it accessible to malicious actors. Organizations must ensure that they are up-to-date with their patch management processes to mitigate risks effectively.

Vulnerability Details

The official description of CVE-2026-7629 states: 'A flaw has been found in kleneway awesome-cursor-mpc-server up to 2.0.1. Impacted is the function runCodeReviewTool of the file src/tools/codeReview.ts of the component Ccode-Review Tool. Executing a manipulation can lead to command injection. The attack may be launched remotely. The exploit has been published and may be used. The project was informed of the problem early through a pull request but has not reacted yet.'

This vulnerability is classified under CWE-74 (Injection) and CWE-77 (Command Injection). The CVSS score is 2.1, indicating a low severity, with the attack vector being network-based. The attack complexity is low, and the privileges required are also low, allowing for a broader range of potential attackers to exploit this flaw.

The vulnerability was published on May 2, 2026, and organizations using affected versions should take note of this disclosure date as they assess their risk.

Technical Analysis

The root cause of CVE-2026-7629 lies in improper input validation within the runCodeReviewTool function. This oversight allows attackers to inject malicious commands that the server executes. The attack can be initiated over the network, requiring low complexity and low privileges, making it accessible to a wider range of threat actors.

No user interaction is required for this vulnerability to be exploited, heightening its risk. The impacts on confidentiality, integrity, and availability are classified as low, but even low-impact vulnerabilities can lead to significant repercussions if left unaddressed.

Risk & Impact Analysis

Risk to organizations includes unauthorized command execution, which could lead to data breaches, loss of data integrity, or service interruptions. Given the remote exploitability of this vulnerability, organizations must evaluate their exposure based on their implementation of the affected component.

The overall blast radius is contingent upon the specific deployment context, but the potential for exploitation is significant enough to warrant immediate attention. The urgency of addressing CVE-2026-7629 is reinforced by the fact that it is publicly known and could be actively targeted by malicious actors.

Exploitation Status

Affected Versions

All versions prior to the vendor patch are affected by CVE-2026-7629. Specifically, the vulnerability impacts kleneway awesome-cursor-mpc-server up to version 2.0.1.

Mitigation & Remediation
