Summary
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.
Risk Assessment
An attacker can steal information available in the victim's browser or perform actions in their session, potentially leading to confidentiality and integrity breaches.
Recommendation
Update Pandora to a patched version that removes the observable value from inline JavaScript.
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-2026-74764Critical
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-2026-75529Medium
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 stored cross-site scripting (XSS) vulnerability in the rendering of URL observables. A URL extracted from or associated with an analyzed file was inserted directly into the inline JavaScript onclick handler used by the Submit to Lookyloo action. Although the value was subject to HTML escaping by the template engine, it was embedded inside a JavaScript string within an HTML attribute. An attacker-controlled URL containing specially crafted characters could therefore break out of the JavaScript string and inject arbitrary JavaScript code. The malicious script would execute in the context of the Pandora web application when a victim interacts with the affected Submit to Lookyloo control. Successful exploitation could allow an attacker to access information available to the victim's browser or perform actions using the victim's authenticated Pandora session. The patch removes the observable value from the inline JavaScript handler. The URL is instead stored in an HTML data-url attribute and retrieved through the DOM dataset API when needed. Additional uses of innerHTML were also replaced with textContent as defensive hardening.
