Key points
- CVE-2026-110643 carries a CVSS score of 9.3, rated critical severity.
- The vulnerability affects transcribe2texts versions up to and including 1.0.6.
- Attackers exploit unescaped inputs in the transcribeAudio() function to run OS commands.
The transcribe2texts library, developed by kky-ykk, contains a critical security flaw that allows remote attackers to execute arbitrary operating system commands. This vulnerability, identified as CVE-2026-110643, affects all versions of the software up to and including 1.0.6. Organizations relying on this Node.js package for audio transcription tasks are directly exposed to this risk. The flaw stems from improper input handling within the core transcription functionality.
By the numbers
- 9.3 is the CVSS base score, indicating a critical severity level for this vulnerability.
- 1.0.6 is the highest affected version of the transcribe2texts library.
- 78 is the CWE identifier, classifying this as a classic OS command injection weakness.
What the figures mean
A CVSS score of 9.3 places this flaw in the highest severity category, demanding immediate attention from security teams. The use of CWE-78 confirms that the application fails to sanitize user-supplied data before passing it to the operating system shell. Specifically, the transcribeAudio() function accepts an audioPath parameter without proper escaping. Attackers can inject shell metacharacters such as dollar signs with parentheses, backticks, or closing quotes into this path. These injections allow command substitution, enabling the execution of arbitrary code with the same privileges as the Node.js process running the application.
What should you do?
Managed service providers must immediately inventory all client environments using transcribe2texts. Teams should verify the specific version installed in each production and development environment. If version 1.0.6 or earlier is present, isolate the affected systems from untrusted networks. Security operations centers should monitor for unusual process spawns or outbound connections from Node.js services. Communicate the risk to development teams to prevent new deployments using this vulnerable library until a secure version is available.
Operational impact
Organizations must determine which internal applications depend on this library for audio processing. Development teams should assess whether custom wrappers mitigate the underlying injection risk. Procurement and vendor management groups need to evaluate the supplier’s response timeline and patching history. Incident response plans should be reviewed to ensure detection capabilities cover shell command execution from Node.js processes. Leadership should be briefed on the potential for full system compromise, as the flaw grants process-level privileges. Communication channels must be established to alert affected clients about the exposure and necessary containment steps.
Background: Incident response plans
Incident response plans fail when teams assume they cover every attack vector or treat them as static documents. You must focus on decision trees, not scripts. Plan for communication breakdowns, not just technical fixes. Regular table-top exercises reveal gaps that documentation hides.

What to do and how to stay safe: transcribe2texts
- Audit all Node.js applications to identify usage of transcribe2texts version 1.0.6 or lower.
- Implement strict input validation for any file paths passed to audio processing functions.
- Monitor system logs for unexpected command executions originating from Node.js processes.
- Restrict network access for servers running vulnerable versions until a vendor update is released.
