Summary
In Streambert versions 2.4.0 and prior, a Zip Slip vulnerability was identified in the subtitle extraction logic. The application does not sanitize archive entry filenames during extraction, allowing for path traversal attacks and writing arbitrary files to the host filesystem.
Risk Assessment
This vulnerability could lead to unauthorized access to the filesystem, posing a serious threat to the organization's data security. An attacker could exploit this flaw to place malicious software anywhere on the server.
Recommendation
It is recommended to update the Streambert application to version 2.5.0, where the issue has been fixed. Additionally, implementing monitoring and security mechanisms is advisable to minimize the risk associated with similar vulnerabilities in the future.
Other vulnerabilities in Streambert
See all- CVE-2026-48056Critical
Streambert before 2.5.0 improperly validates executable paths supplied to the run-download IPC handler, allowing a compromised renderer to execute arbitrary local binaries with the app's privileges.
- CVE-2026-48046Critical
Streambert before 2.5.0 has an unvalidated auto-updater URL vulnerability that allows a compromised renderer to make the main process download and execute an arbitrary binary, resulting in remote code execution.
- CVE-2026-52877High
Vulnerability in Streambert (before 2.6.0) in the open-external IPC handler, which passes a renderer-supplied URL to shell.openExternal without protocol validation. A compromised renderer can open local files or launch applications.
- CVE-2026-52876High
Vulnerability in Streambert (before 2.6.0) in the open-path-at-time IPC handler, which passes a renderer-controlled file path to shell.openPath without validation. A compromised renderer can launch a local executable or script.
- CVE-2026-52875High
Vulnerability in Streambert (before 2.6.0) in the perform-scheduled-backup IPC handler, which uses a renderer-supplied path for file operations without checking if it is in an authorized location. A compromised renderer can create directories, write files, and delete files anywhere.
- CVE-2026-52873Medium
Vulnerability in Streambert (from 2.5.0 to 2.6.0) allows script injection in the Wyzie key redemption window, which removes the CSP header and lacks window open restrictions, enabling malicious script execution in the application context.
- CVE-2026-52872High
Vulnerability in Streambert (before 2.5.0) in the downloadSubtitleFile function, which accepts a renderer-supplied URL with file: scheme and copies the file to a chosen location. A compromised renderer can copy any file readable by the StreamBERT process.
Original NVD description (English source)
Streambert is a cross-platform Electron Desktop App to stream and download any video media. In versions 2.4.0 and prior, a high-severity Zip Slip vulnerability was identified in Streambert's subtitle extraction logic. The application does not sanitize archive entry filenames during extraction, allowing a malicious archive to perform path traversal and write arbitrary files to the host filesystem. The subtitle extraction process downloads a ZIP archive and extracts its entries. The destination file path is constructed by concatenating the raw archive entry name (extracted.name) directly to the temporary directory path. If a malicious ZIP archive containing directory traversal sequences is processed, it escapes the temporary directory boundaries. The application then writes the extracted payload anywhere on the host filesystem subject to the application's current write permissions. This issue has been fixed in version 2.5.0.
