Published: 17 February 2026
Summary
CVE-2026-2629 is a medium-severity Command Injection (CWE-77) vulnerability. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 37.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-2629 is an OS command injection vulnerability (CWE-77, CWE-78) in the jishi/node-sonos-http-api project, affecting commits up to 3776f0ee2261c924c7b7204de121a38100a08ca7. The flaw resides in the Promise function of the lib/tts-providers/mac-os.js file within the TTS Provider component, where manipulation of the 'phrase' argument enables command injection.
Attackers can exploit this remotely without authentication or user interaction, given the CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Unauthenticated remote parties can achieve limited impacts on confidentiality, integrity, and availability, such as executing arbitrary OS commands on the host system running the affected software.
The project uses a rolling release model, providing no specific details on affected or patched commits. It was informed early via GitHub issue #915 but has not responded. No mitigations or patches are mentioned in available advisories from VulDB or the referenced research repository.
A public exploit is available and could be used for attacks, as noted in vulnerability databases.

Why these techniques?
OS command injection in public-facing node-sonos-http-api (mac-os.js TTS provider) enables remote unauthenticated RCE via arbitrary shell commands.

Directly requires validation and sanitization of the untrusted 'phrase' argument before it reaches the OS command execution path in mac-os.js, blocking the CWE-78 injection.
Limits the privileges of the node process running the TTS provider so that any injected OS commands have minimal impact on confidentiality, integrity, or availability.
Restricts the set of OS commands and utilities available to the TTS component, reducing the attack surface that the unsanitized phrase can exploit.
