CVE-2026-7246

7.2

Pallets · Click

A command injection vulnerability in the click.edit() function allows attackers to execute arbitrary OS commands.

Executive summary

A command injection vulnerability exists in the Pallets Click library that could allow an attacker with high privileges to execute arbitrary OS commands on the host system.

Vulnerability

The application contains an improper neutralization of special elements in the click.edit() function, which enables command injection. Per the CVSS vector, this vulnerability requires high privileges (PR:H) and user interaction (UI:R) to execute.

Business impact

Successful exploitation allows an attacker to execute arbitrary commands at the operating system level, potentially leading to a full system compromise. While the CVSS score of 7.2 indicates a high severity, the requirement for high privileges and user interaction limits the immediate attack surface. However, the potential for total impact on confidentiality, integrity, and availability necessitates prompt remediation.

Remediation

Immediate Action: Update the Pallets Click library to version 8.3.3 or later to incorporate the necessary security patches.

Proactive Monitoring: Monitor system logs for unusual process execution patterns or unexpected command-line activity originating from services utilizing the Click library.

Compensating Controls: Restrict access to the administrative interfaces or functions that invoke the click.edit() method to minimize the risk of privilege escalation or unauthorized command execution.

Exploitation status

Public Exploit Available: Unknown.

Analyst recommendation

Organizations utilizing the Pallets Click library should verify their current version and update to 8.3.3 immediately. Despite the specific privilege requirements for exploitation, the severity of a command injection flaw warrants rapid deployment of the provided vendor fix to prevent potential system-level compromise.
