Summary

CVE-2025-70039 is a critical-severity OS Command Injection (CWE-78) vulnerability in Linagora Twake. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 29.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2025-70039 is a critical vulnerability, scored at 9.8 under CVSS 3.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), stemming from CWE-78: Improper Neutralization of Special Elements used in an OS Command. It affects Linagora Twake version 2023.Q1.1223, an open-source collaboration platform. The issue enables OS command injection due to inadequate sanitization of user-supplied inputs passed to system commands.

Remote attackers require no authentication, privileges, or user interaction and can exploit the flaw over the network with low attack complexity. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, allowing arbitrary OS command execution on the affected system and potential full compromise of the Twake instance.

Mitigation details are available in vendor resources, including the Linagora GitHub organization at https://github.com/linagora, the Twake repository at https://github.com/linagora/Twake, and a specific advisory gist at https://gist.github.com/zcxlighthouse/62ad88841b308e184220af2f3c19ec38. The CVE was published on 2026-03-09T18:16:15.210.
