CVE-2026-52876: CWE-20: Improper Input Validation in truelockmc streambert
Streambert, a cross-platform Electron desktop app for streaming and downloading video content, has an improper input validation vulnerability in versions prior to 2.6.0. The open-path-at-time IPC handler accepts a file path from the renderer process without validating its type or location. If attempts to launch mpv or VLC are skipped or fail, the handler passes this file path to Electron's shell.openPath, which can cause the operating system to execute arbitrary files with the privileges of the Streambert process. This allows a compromised renderer to escape the sandbox and execute local executables or scripts. The issue is fixed in version 2.6.0.
AI Analysis
Technical Summary
CVE-2026-52876 is an improper input validation vulnerability (CWE-20) in the open-path-at-time IPC handler of Streambert prior to version 2.6.0. The handler accepts a renderer-controlled filePath without verifying its type or location. If launching mpv or VLC is skipped or fails, the filePath is passed to Electron's shell.openPath, which executes the file with the application's privileges. This can lead to sandbox escape and arbitrary code execution with the privileges of the Streambert process. The vulnerability is resolved in version 2.6.0.
Potential Impact
An attacker controlling the renderer process can supply a malicious file path that causes the operating system to execute arbitrary local executables, scripts, or shortcuts with the privileges of the Streambert application. This enables sandbox escape and full compromise of the application context, potentially leading to high confidentiality, integrity, and availability impact.
Mitigation Recommendations
This vulnerability is fixed in Streambert version 2.6.0. Users should upgrade to version 2.6.0 or later to remediate this issue. No additional mitigation is required once the update is applied.
