Vulnerability Title
Rust OneNote File Parser: Path traversal in `Parser::parse_notebook` allows reading files outside the notebook directory
Vulnerability Description
Rust OneNote File Parser is a parser for Microsoft OneNote files implemented in Rust. Prior to version 1.1.1, a maliciously crafted `.onetoc2` table-of-contents file can cause `Parser::parse_notebook` to open arbitrary files on the host filesystem outside the notebook's directory. The parser reads entry names listed inside the `.onetoc2` and joins them against the notebook's base directory without validating that they are relative paths confined to that directory. The parser will bail out when the target file fails to parse as a OneNote section, so direct content exfiltration through the parser's return value is not practical, though file-existence probing and denial-of-service via large or special files remain possible. Anyone using `onenote_parser` to parse .onetoc2 files received from untrusted sources is affected. Users who only ever parse their own notebooks are not at meaningful risk. The issue is fixed in onenote_parser 1.1.1. The fix rejects absolute paths, parent-directory components, and other invalid path characters in entry names, and additionally canonicalises the resolved path to confirm it stays inside the notebook's base directory. For users who cannot upgrade to 1.1.1, only call `Parser::parse_notebook` on `.onetoc2` files from trusted sources. Alternatively, use `Parser::parse_section` / `Parser::parse_section_buffer` on individual .one files, which do not perform the directory walk.

Vulnerability Title
Markus Siemens Rust OneNote® File Parser 路径遍历漏洞
Vulnerability Description
Markus Siemens Rust OneNote® File Parser是德国Markus Siemens个人开发者的一个Rust语言编写的OneNote文件解析组件。 Markus Siemens Rust OneNote® File Parser 1.1.1之前版本存在路径遍历漏洞,该漏洞源于解析器对 .onetoc2 目录项中路径验证不足,可能导致恶意特制的文件打开主机文件系统上的任意文件,造成文件存在探测和拒绝服务。
