7DescriptionCVE.org
A weakness has been identified in frdel/agent0ai agent-zero 0.9.7. This affects the function handle_pdf_document of the file python/helpers/document_query.py. This manipulation causes server-side request forgery. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
A Server-Side Request Forgery (SSRF) vulnerability exists in frdel/agent-zero version 0.9.7 within the handle_pdf_document function of python/helpers/document_query.py. This allows authenticated remote attackers to manipulate PDF document handling to perform arbitrary server-side requests, potentially accessing internal services or exfiltrating sensitive data. …

Vulnerability AssessmentAI
| Risk Assessment | The CVSS 3.1 score of 6.3 (Medium severity) reflects a network-accessible vulnerability requiring low privileges (PR:L) with low attack complexity (AC:L), resulting in limited confidentiality, integrity, and availability impact (C:L/I:L/A:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated user uploads a crafted PDF file to an Agent-Zero instance where the handle_pdf_document function processes the document. The PDF contains embedded or injected URL parameters that the function fails to validate before making backend requests. … |
| Remediation | Immediately upgrade Agent-Zero to a patched version released after 0.9.7 (check the frdel/agent-zero GitHub repository at https://github.com/frdel/agent-zero for availability). … Detailed patch versions, workarounds, and compensating controls in full report. |
