Should you act?
Exploited: patch now if you run it
CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Yes, if you run Sangoma FreePBX. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-02-03, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-02-24; treat that as the outer limit, not the target.
- EPSS 84.6%, percentile 99.7: FIRST’s model estimates a 84.6% chance of exploitation activity in the next 30 days, higher than 99.7% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
What it is
FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. In versions 17.0.2.36 and above before 17.0.3, the filestore module within the Administrative interface is vulnerable to a post-authentication command injection by an authenticated known user via the testconnection -> checksshconnect() function. An attacker can leverage this vulnerability to obtain remote access to the system as an asterisk user. This issue is fixed in version 17.0.3.
