CVE-2021-46417
Published: April 11, 2026
Official Description
Insecure handling of a download function leads to disclosure of internal files due to path traversal with root privileges in Franklin Fueling Systems Colibri Controller Module 1.8.19.8580.
Risk Analysis
A path traversal vulnerability in Franklin Fueling Systems Colibri Controller Module 1.8.19.8580 allows for unauthorized disclosure of internal files with root privileges. Its presence in CISA's KEV catalog and active exploitation make this a critical vulnerability.
This vulnerability is actively exploited in the wild, as indicated by its inclusion in CISA's KEV. The path traversal flaw, combined with root privileges, suggests a high impact if exploited remotely.
Update Franklin Fueling Systems Colibri Controller Module to a patched version. Restrict network access to the controller and monitor for unusual file access patterns.
Technical Analysis
CVE-2021-46417 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2021-46417 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
