CVE-2026-117183 Details
Description
A path traversal vulnerability in the FeaturedImage component of astro-notion-blog 0.13.0 allows attackers to escape the intended directory, as well as read and overwrite files on the server via a crafted URL.
A path traversal vulnerability has been identified in the FeaturedImage component of astro-notion-blog version 0.13.0. This vulnerability allows attackers to escape the intended directory and read or overwrite files on the server by using a crafted URL. The issue arises because the downloadFile() function in the Notion client library improperly handles URL decoding and file path construction, enabling exploitation during the build process.
The vulnerability can be remediated by validating and sanitizing the file paths before writing them to the server. This includes ensuring that the paths do not escape the intended directory and do not contain unsafe characters or patterns. Additionally, restricting the FeaturedImage URLs to only accept certain types of content could help mitigate the risk.
