CVE-2026-52873: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in truelockmc streambert
CVE-2026-52873 is a cross-site scripting (XSS) vulnerability in the Streambert Electron desktop app versions prior to 2.6.0. The vulnerability arises because the wyzie-open-redeem IPC handler removes the Content-Security-Policy header in a specific Electron session, allowing script injection from a third-party resource or navigated sites without CSP restrictions. Exploitation requires user interaction to open the Wyzie API key redemption window and attacker-controlled script content in a loaded page. This can lead to execution of malicious scripts that invoke application functionality and potentially access sensitive data. The issue is fixed in version 2.6.0.
AI Analysis
Technical Summary
Streambert versions from 2.5.0 up to but not including 2.6.0 contain a cross-site scripting vulnerability due to the removal of the Content-Security-Policy header in the wyzie-redeem Electron session. The redeem window lacks restrictions on window opening, enabling injected scripts from sub.wyzie.io or navigated sites to execute without CSP constraints. This allows attacker-controlled scripts to run in the renderer process, potentially invoking application functions and chaining with other vulnerabilities to access internal services or sensitive data. Exploitation requires user interaction to open the redemption window and attacker-controlled content in a loaded page. The vulnerability is resolved in version 2.6.0.
Potential Impact
Successful exploitation can lead to execution of attacker-controlled scripts within the application context, potentially allowing access to sensitive data and invocation of application functionality. The vulnerability requires user interaction and attacker-controlled script content in a loaded page. The CVSS 3.1 score is 6.9 (medium severity), reflecting network attack vector, high complexity, no privileges required, user interaction required, scope changed, high confidentiality impact, low integrity impact, and no availability impact.
Mitigation Recommendations
This vulnerability is fixed in Streambert version 2.6.0. Users and administrators should upgrade to version 2.6.0 or later to remediate this issue. No additional mitigations are indicated by the vendor advisory.
