What is CVE-2025-53371?

The DiscordNotifications extension for MediaWiki is vulnerable due to its ability to send requests to arbitrary URLs defined by the user. This functionality can lead to Denial of Service (DoS) attacks by requesting large files, overwhelming the server. Additionally, if there are internal APIs that lack proper protection, attackers could exploit this vulnerability using HTTP POST requests, potentially leading to Remote Code Execution (RCE). The issue has been addressed in commit 1f20d850cbcce5b15951c7c6127b87b927a5415e.
