AI Analysis
Technical Summary
CVE-2026-17613 describes a vulnerability in Penpot where the ::import-binfile RPC command does not properly authorize the optional file-id parameter. As a result, any authenticated user can overwrite files on the server and subscribe to WebSocket events. This can enable attackers to exfiltrate data or poison data on the system. The vulnerability is classified under CWE-862 (Missing Authorization). The CVSS 3.1 base score is 7.5, indicating a high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and impact primarily on availability.
Potential Impact
An attacker with authentication can overwrite arbitrary files on the server and subscribe to WebSocket events, potentially leading to full data exfiltration and data poisoning. This compromises the integrity and availability of the system and data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided. Until a patch is available, restrict authenticated user permissions and monitor for suspicious activity related to the ::import-binfile RPC command.
