No official patch or remediation guidance is currently available, and no known exploits in the wild have been reported.
AI Analysis
Technical Summary
CVE-2026-30117 describes a critical arbitrary file upload vulnerability in scalar/astro version 0.1.13. The vulnerability resides in the scalar_url query parameter of the Scalar Proxy endpoint, enabling attackers to upload malicious SVG files that can execute arbitrary code on the affected system. The CVSS v3.1 base score is 9.8, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No patch or official remediation level has been published as of the data provided.
Potential Impact
Successful exploitation can result in full system compromise due to arbitrary code execution. Confidentiality, integrity, and availability of the affected system are all critically impacted. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the Scalar Proxy endpoint and monitor for suspicious file uploads. Avoid processing untrusted SVG files through the vulnerable parameter.
