CVE-2026-111915 Details
Description
Yank Note before 3.93.1 contains a path traversal vulnerability that allows unauthenticated remote attackers to read arbitrary files via the path or doc parameter of /api/help. Attackers can supply repeated '../' segments, which bypass the single-replacement sanitization in the publicly allowlisted endpoint, to read SSH keys, configuration, or notes.
A path traversal vulnerability has been identified in Yank Note versions prior to 3.93.1. This vulnerability allows unauthenticated remote attackers to read arbitrary files through the 'path' or 'doc' parameters of the '/api/help' endpoint. The issue arises because the endpoint's input sanitization only removes the first occurrence of '../', allowing attackers to bypass restrictions and access sensitive files such as SSH keys, configuration files, or personal notes.
Users can upgrade to Yank Note version 3.93.1 or later, where this vulnerability has been fixed.
