CVE-2026-7246
Description
A flaw was found in Pallets Click. This command injection vulnerability, located in the click.edit() function, allows an attacker with an unprivileged account to execute arbitrary operating system (OS) commands. This could lead to unauthorized control over the affected system.
Statement
A command injection vulnerability exists in the click.edit() function of the Pallets Click library. The filename parameter is not sanitized before being interpolated into a shell command string, allowing an attacker who controls the filename to inject and execute arbitrary OS commands.
The root cause is in edit_files(), which wraps the filename in double quotes and passes the resulting string to subprocess.Popen() with shell=True. A filename containing a double-quote character (") can break out of the quoting context and introduce arbitrary shell metacharacters.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
