A vulnerability was detected in PromtEngineer localGPT up to 4d41c7d1713b16b216d8e062e51a5dd88b20b054. Impacted is the function LocalGPTHandler of the file backend/server.py of the component API Endpoint. The manipulation of the argument BaseHTTPRequestHandler results in missing authentication. The attack can be executed remotely. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Authentication bypass in PromtEngineer localGPT affects the LocalGPTHandler API endpoint in backend/server.py, allowing unauthenticated remote attackers to access protected functionality with low confidentiality, integrity, and availability impact. The vulnerability stems from improper validation of the BaseHTTPRequestHandler argument, enabling attackers to manipulate request handling without credentials. …

Vulnerability AssessmentAI
| Risk Assessment | While the CVSS 4.0 score of 6.9 indicates a medium-severity vulnerability with low confidentiality, integrity, and availability impact, the overall real-world risk must be contextualized. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker on the same network or with network access to the localGPT API endpoint (typically running on localhost:port) sends an HTTP request directly to the LocalGPTHandler API endpoint without providing any authentication credentials. Due to missing credential validation in the BaseHTTPRequestHandler argument processing, the handler accepts the request and processes it, potentially allowing the attacker to query the underlying language model, retrieve configuration details, or trigger other backend operations that should have been protected. … |
| Remediation | Users should immediately update to a commit version more recent than 4d41c7d1713b16b216d8e062e51a5dd88b20b054 by pulling the latest upstream code from the PromtEngineer repository on GitHub. … Detailed patch versions, workarounds, and compensating controls in full report. |
