jsPDF has Local File Inclusion/Path Traversal vulnerability

jsPDF is a library to generate PDFs in JavaScript. Prior to version 4.0.0, user control of the first argument of the loadFile method in the node.js build allows local file inclusion/path traversal. If given the possibility to pass unsanitized paths to the loadFile method, a user can retrieve file contents of arbitrary files in the local file system the node process is running in. The file contents are included verbatim in the generated PDFs. Other affected methods are `addImage`, `html`, and `addFont`. Only the node.js builds of the library are affected, namely the `dist/jspdf.node.js` and `dist/jspdf.node.min.js` files. The vulnerability has been fixed in jsPDF@4.0.0. This version restricts file system access per default. This semver-major update does not introduce other breaking changes. Some workarounds areavailable. With recent node versions, jsPDF recommends using the `--permission` flag in production. The feature was introduced experimentally in v20.0.0 and is stable since v22.13.0/v23.5.0/v24.0.0. For older node versions, sanitize user-provided paths before passing them to jsPDF.

jsPDF 安全漏洞

jsPDF是Parallax开源的一款基于JavaScript的PDF文档生成库。 jsPDF 4.0.0之前版本存在安全漏洞，该漏洞源于loadFile等方法允许用户控制路径，可能导致本地文件包含或路径遍历攻击。
