Researchers have disclosed a previously undocumented local file inclusion ( LFI ) vulnerability in Hashnode , a developer-oriented blogging platform, that could be abused to access sensitive data such as SSH keys, server's IP address, and other network information. "The LFI originates in a Bulk Markdown Import feature that can be manipulated to provide attackers with unimpeded ability to download local files from Hashnode's server," Akamai researchers said in a report shared with The Hacker News. Local file inclusion flaws occur when a web application is tricked into exposing or running unapproved files on a server, leading to directory traversal, information disclosure, remote code execution, and cross-site scripting (XSS) attacks. The flaw, caused due to the web application failing to adequately sanitize the path to a file that's passed as input, could have serious repercussions in that an assailant could navigate to any path on the server and access s
