CVE-2026-54710 Details
FreePBX is an open source IP PBX. Prior to versions 16.0.40 and 17.0.7, a critical remote code execution (RCE) vulnerability exists in the superfecta module due to unsafe inclusion of arbitrary PHP files, allowing authenticated attackers to execute arbitrary PHP code on the server with the privileges of the web server user. Authentication with a known username is required. The vulnerability is rooted in the options and save_options cases in the Superfecta module's AJAX handler. The code dynamically includes PHP files from the sources/ directory based on user-supplied input. This allows an attacker to execute arbitrary code when combined with arbitrary directory creation (e.g., via the backup module) and file uploads that reveal full paths (e.g., via the soundlang module). This issue has been patched in versions 16.0.40 and 17.0.7.

Exploit prediction scoring system (EPSS) score for CVE-2026-54710
EPSS (Exploit Prediction Scoring System): EPSS predicts the likelihood that a vulnerability will be exploited in the wild. A higher percentage means a greater chance of an exploit occurring. The EPSS model produces a probability score between 0 and 1 (0 and 100%).
0.51 Probability of exploitation activity being observed over the next 30 days (44th percentile)
CVSS score for CVE-2026-54710
CVSS (Common Vulnerability Scoring System): An open framework owned and managed by FIRST.Org, Inc. that assigns a numerical score from 0 to 10 to software vulnerabilities to indicate their severity.

Bitsight Data Discovery and Continuous Threat Scanning

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
