#path-traversal

The jsPDF library for generating PDF documents in JavaScript applications is vulnerable to a critical vulnerability that allows an attacker to steal sensitive data from the local filesystem by including it in generated files. The flaw is a local file inclusion and path traversal that allows passing unsanitized paths to the file loading mechanism (loadFile) in jsPDF versions before 4.0. It is tracked as CVE-2025-68428 and received a severity score of 9.2.

If a developer uses MultipartFile.move() without the second options argument or without explicitly sanitizing the filename, an attacker can supply a crafted filename value containing traversal sequences, writing to a destination path outside the intended upload directory," the project maintainers said in an advisory released last week. "This can lead to arbitrary file write on the server. However, successful exploitation hinges on a reachable upload endpoint.

The first chain involves two vulnerabilities ( CVE-2025-57791 and CVE-2025-57790), an argument injection in CommServe and a path traversal bug respectively. The severity scores for the flaws are not especially concerning on their own, but chained together they become more dangerous. In Commvault's advisory, it describes CVE-2025-57791 as a vulnerability that allows attackers to retrieve a valid user session for a low-privilege role, assigning it a CVSS score of 6.9 (medium severity).
