CVE-2026-46515 in Frogman
Summary
by MITRE • 07/16/2026
Frogman provides headless PBX control through MCP and HTTP API. Prior to 1.6.3, PERM_READ access was sufficient to call fm_list_managers, fm_list_pinsets, fm_show_context, fm_get_mcp_config, fm_backup_status, fm_whos_calling, fm_run_saved_query, and fm_diagnose_trunk, exposing AMI manager secrets, outbound dial PINs, full Asterisk dialplan context, root SSH connection commands, backup artifact paths, CDR history, arbitrary saved GraphQL query execution, and raw AMI endpoint dumps containing SIP fields such as password, md5_cred, and oauth_secret. This issue is fixed in version 1.6.3.

Analysis

The Frogman application presents a critical privilege escalation vulnerability through its headless PBX control mechanisms leveraging MCP and HTTP API interfaces. This flaw exists within the access control implementation where users with only PERM_READ permissions can execute a broad range of administrative functions that were intended to be restricted to higher privilege levels. The vulnerability affects versions prior to 1.6.3, indicating a long-standing security weakness in the application's authorization model that could have been exploited for extended periods without detection.
The technical exploitation of this vulnerability enables attackers with minimal privileges to access sensitive system information through multiple exposed API endpoints. The fm_list_managers function reveals AMI manager secrets that provide direct access to Asterisk's Manager Interface, while fm_list_pinsets exposes outbound dial PINs that could enable unauthorized calling. The fm_show_context endpoint provides full visibility into the Asterisk dialplan context, allowing attackers to understand system call routing and identify potential attack vectors. Additionally, the exposure of root SSH connection commands through fm_get_mcp_config creates opportunities for privilege escalation at the system level.
The impact extends beyond simple information disclosure to include complete system compromise potential through multiple attack vectors. The fm_backup_status endpoint reveals backup artifact paths that could be exploited to access sensitive backup files containing additional credentials or system configurations. The fm_whos_calling and fm_run_saved_query functions provide real-time call monitoring capabilities and arbitrary query execution respectively, while fm_diagnose_trunk exposes raw AMI endpoint dumps containing critical authentication fields such as passwords, md5_cred values, and oauth_secret tokens that could be used for further unauthorized access.
This vulnerability directly maps to CWE-284 (Improper Access Control) and represents a classic case of insufficient authorization checks in web applications. The ATT&CK framework categorizes this under privilege escalation techniques where initial access can be leveraged to gain higher privileges through the exploitation of weak access controls. The exposure of multiple credential types including OAuth secrets and MD5 credentials creates cascading security risks that could enable attackers to establish persistent access to the underlying Asterisk system.
Organizations using Frogman should immediately implement the remediation provided in version 1.6.3 which properly enforces access control restrictions for these administrative functions. The fix requires proper privilege validation before executing sensitive operations, ensuring that only users with appropriate administrative permissions can access these endpoints. Network segmentation and monitoring of API access patterns should be implemented to detect potential exploitation attempts, while credential rotation should occur for any exposed secrets that may have been compromised during the vulnerability's active period.
The broader implications highlight the importance of principle of least privilege implementation in telephony management systems where administrative functions are exposed through web APIs. This vulnerability demonstrates how seemingly minor access control oversights can provide attackers with comprehensive system reconnaissance capabilities and direct paths to full system compromise. Regular security assessments of API endpoints and access control mechanisms should be conducted to identify similar issues in other applications within the telecommunications infrastructure that may present similar exposure risks.
