CVE-2026-52100 Details
Description
Cross Site Request Forgery vulnerability in andreimarcu linux-server v.1.0 through v.2.3.8 allows a remote attacker to execute arbitrary code via the uploadPutHandler function
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in Linx-Server versions 1.0 through 2.3.8. The issue arises because the PUT upload handler does not implement the same origin validation as the POST handler, allowing remote attackers to upload files without proper referrer checks. This vulnerability could be exploited to execute arbitrary code by uploading malicious files that are then processed by the server.
To address this vulnerability, the Linx-Server maintainer should apply the same origin checks to the PUT upload handler, validate the Origin and Referer headers consistently across all methods that change server state, and consider implementing CSRF tokens for operations that modify server state.
