CVE-2026-93982: Insertion of Sensitive Information into Log File in Openpanel-dev openpanel
OpenPanel through commit bad75bdd writes Model Context Protocol authentication tokens from URL query parameters to plaintext application logs without redaction. Attackers with access to application stdout or centralized logging systems can capture base64-encoded credentials to replay MCP requests and access project analytics.
AI Analysis
Technical Summary
CVE-2026-93982 describes a vulnerability in OpenPanel (openpanel) version 0 where MCP authentication tokens passed via URL query parameters are written to plaintext logs without any redaction. An attacker who can access these logs can extract base64-encoded credentials and replay MCP requests, gaining unauthorized access to project analytics data.
Potential Impact
The vulnerability exposes sensitive authentication tokens in plaintext logs, enabling attackers with log access to capture credentials and replay requests to access project analytics. This could lead to unauthorized data access but requires attacker access to application logs or stdout streams.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to application logs and stdout streams to trusted personnel only to prevent credential leakage.
