CVE-2026-53458: CWE-209: Generation of Error Message Containing Sensitive Information in ha-china blueprint-studio
CVE-2026-53458 is a vulnerability in the ha-china blueprint-studio, a VS Code-like editor for Home Assistant configuration files. Versions prior to 2.5.2 expose raw exception messages containing sensitive information such as internal filesystem paths and implementation details to authenticated users. This information disclosure could aid attackers in fingerprinting the Home Assistant installation and planning further attacks. The issue is resolved in version 2.5.2.
AI Analysis
Technical Summary
Blueprint Studio backend API handlers in custom_components/blueprint_studio/backend/api.py returned raw exception strings to authenticated users before version 2.5.2. These exception messages could reveal sensitive internal filesystem paths and implementation details, constituting a CWE-209: Generation of Error Message Containing Sensitive Information. This vulnerability allows authenticated users to gain information that could be used to refine subsequent attacks. The vulnerability has a CVSS 4.0 base score of 5.3 (medium severity) and is fixed in version 2.5.2.
Potential Impact
Authenticated users could obtain sensitive internal information such as filesystem paths and implementation details from error messages. This information disclosure may facilitate fingerprinting of the Home Assistant installation and improve the effectiveness of follow-up attacks. There is no indication of direct code execution or privilege escalation from this vulnerability.
Mitigation Recommendations
Upgrade blueprint-studio to version 2.5.2 or later, where this issue is fixed. No other mitigation is required as the fix is available.
