CVE-2026-88069
CriticalCVSS 9.3Summary
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.
Risk Assessment
Risk includes unauthorized modification of application or system files, denial of service, and potentially further compromise depending on the permissions of the Pandora process and the files that can be overwritten.
Recommendation
Apply the fix that resolves each extraction destination path before writing and verifies that it remains below the expected extraction directory, rejecting attempts that resolve outside.
Other vulnerabilities in Pandora
See all- CVE-2026-74764Critical
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.
- 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 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. Successful exploitation could result in unauthorized modification of application or system files, denial of service, and potentially further compromise depending on the permissions of the Pandora process and the files that can be overwritten. The vulnerability is addressed by resolving each extraction destination path before writing and verifying that it remains below the expected extraction directory. Extraction attempts resolving outside this directory are rejected and reported as path traversal attempts.
