Summary
Pandora contains a path traversal vulnerability in its TAR archive extraction functionality. When processing a TAR archive, member names are passed directly to Python's tarfile.TarFile.extract() without an extraction filter. An attacker can submit a crafted TAR archive with malicious paths, allowing files to be written outside the intended directory.
Risk Assessment
An attacker can overwrite files accessible to the Pandora worker process, potentially leading to application compromise, arbitrary code execution, or denial of service depending on file targets and process privileges.
Recommendation
Apply the fix that uses Python's 'data' extraction filter to reject or sanitize dangerous TAR members, including paths that escape the destination directory.
Other vulnerabilities in Pandora
See all- CVE-2026-88069Critical
Pandora contains a path traversal vulnerability in its archive extraction worker. When processing a specially crafted archive or disk image, attacker-controlled file paths could be used without ensuring that the resulting destination remained within the intended extraction directory. An attacker able to submit a malicious file for analysis could use path traversal sequences or crafted paths to cause extracted content to be written outside the designated extraction directory, potentially overwriting files accessible to the Pandora worker process.
- CVE-2026-75531High
Pandora contains a stored XSS vulnerability in the rendering of URL observables. A malicious URL can be injected into the inline JavaScript onclick handler, allowing arbitrary JavaScript execution in the application context.
- CVE-2026-75529Medium
Pandora is affected by a stored XSS vulnerability in the PDF download functionality. The /task-download/<task_id>/.../pdf endpoint verifies the file is a PDF but returns it without explicit MIME type, allowing it to be served as HTML or another active format. A crafted PDF/polyglot can execute script in the Pandora application context.
- CVE-2026-74767High
Pandora contains a denial-of-service vulnerability in its handling of DAA (Direct Access Archive) files. When extracting the internal ISO image, compressed chunks are decompressed using zlib.decompress() without enforcing a limit on the resulting uncompressed data. An attacker can submit a crafted DAA file with highly compressed data, causing excessive memory and CPU consumption, potentially making the extraction worker unresponsive or terminating it, affecting service availability.
Original NVD description (English source)
Pandora contains a path traversal vulnerability in its TAR archive extraction functionality. When processing a submitted TAR archive, the extractor passed archive member names directly to Python's tarfile.TarFile.extract() without applying an extraction filter. An attacker able to submit a specially crafted TAR archive containing malicious member paths, such as paths using ../ sequences or absolute paths, could cause extracted files to be written outside the intended extraction directory. This may allow the attacker to overwrite files accessible to the Pandora worker process and could potentially result in application compromise, arbitrary code execution, or denial of service depending on the files targeted and the privileges of the Pandora process. The vulnerability is corrected by using Python's filter='data' extraction filter, which rejects or sanitizes dangerous TAR members, including paths that escape the destination directory and unsafe link targets. The weakness corresponds to MITRE's general path traversal category, which includes archive extraction cases where attacker-controlled filenames cause files to be written outside the intended directory.
