CVE-2026-62378: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in rustfs console
CVE-2026-62378 is a critical stored cross-site scripting (XSS) vulnerability in the RustFS Console web management interface. It affects versions from 0.1.7 up to but not including 0.1.10. The vulnerability arises because certain components render HTML content uploaded as .pdf files, allowing malicious scripts to execute. This can lead to exposure of sensitive administrator credentials including AccessKeyId, SecretAccessKey, and SessionToken. The issue is a regression of a previous vulnerability (CVE-2026-27822) and is fixed in version 0.1.10.
AI Analysis
Technical Summary
RustFS Console versions >=0.1.7 and <0.1.10 contain a stored cross-site scripting vulnerability in the components/object/preview-modal.tsx and components/object/pdf-viewer.tsx files. The vulnerability occurs because the PDF preview feature improperly renders HTML content embedded in .pdf files, enabling attackers to execute arbitrary scripts in the management console context. This can expose critical administrator credentials such as AccessKeyId, SecretAccessKey, and SessionToken. The vulnerability is a regression of CVE-2026-27822 and is resolved in version 0.1.10.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary scripts within the RustFS Console management interface, leading to full compromise of administrator credentials (AccessKeyId, SecretAccessKey, and SessionToken). This can result in unauthorized access and control over the RustFS distributed file system environment. The CVSS score of 9.0 reflects a critical impact with high confidentiality, integrity, and availability consequences.
Mitigation Recommendations
This vulnerability is fixed in RustFS Console version 0.1.10. Users should upgrade to version 0.1.10 or later to remediate this issue. Patch status is not explicitly confirmed in the vendor advisory, but the description states the issue is fixed in 0.1.10. No additional mitigations are specified.
