Severe jsPDF flaw lets hackers rob secrets and ways by scheme of generated PDFs
Identity theft
The jsPDF library for generating PDF paperwork in JavaScript functions is at possibility of a necessary vulnerability that enables an attacker to rob sensitive files from the native filesystem by collectively with it in generated files.
The flaw is a native file inclusion and path traversal that enables passing unsanitized paths to the file loading mechanism (loadFile) in jsPDF versions earlier than 4.0. It’s tracked as CVE-2025-68428 and bought a severity discover of 9.2.
In jsPDF’s Node.js builds, the ‘loadFile’ characteristic is normal for studying the native filesystem. The topic arises when user-managed enter is passed because the file path, inflicting jsPDF to consist of into the generated PDF output the explain material of the file.
Exploitation instance Supply: Parallax
Other file loading methods are also affected, collectively with ‘addImage’, ‘html’, and ‘addFont’, as all can call the loadFile characteristic.
Per the jsPDF security bulletin, the sector handiest impacts the Node.js builds of the library, namely the dist/jspdf.node.js and dist/jspdf.node.min.js files.
In a detailed technical file, application security firm Endor Labs says that the exploitation possibility is low or nonexistent if file paths are hardcoded, advance from a relied on configuration, or strict allowlists are normal for inputs.
CVE-2025-68428 changed into as soon as mounted in model 4.0.0 of jsPDF by restricting filesystem discover admission to by default and relying as but any other on Node.js permission mode.
Nonetheless, Endor Labs researchers demonstrate that this mode is experimental in Node 20, so versions 22.13.0, 23.5.0, or 24.0.0 and later are on the spot.
One other caveat to clutch into epic is that enabling the ‘–permission’ flag, a workaround on the spot by the developers, impacts your complete Node.js process, no longer moral jsPDF.
Endor Labs also underlines that overly gigantic filesystem permissions added to the ‘–allow-fs-learn’ configuration flag teach the fix.
