CyberRota Analysis
AI-GeneratedHedgeDoc versions prior to 1.11.0 are vulnerable to an IP spoofing attack that allows attackers to bypass rate-limiting on the /login and /register routes, enabling them to spam login attempts or create multiple accounts. This vulnerability arises from the application’s reliance on the CloudFlare cf-connecting-ip header, which can be manipulated by malicious users. Organizations using affected versions should prioritize upgrading to 1.11.0 or later to mitigate the risk of account abuse and service disruption.

Original NVD Description
HedgeDoc is an open source, real-time, collaborative, markdown notes application. Versions prior to 1.11.0 allowed attackers to circumvent the rate-limiting of the /login and /register routes by spoofing IP addresses. HedgeDoc instances checked for CloudFlare's cf-connecting-ip header and used that instead of the users real IP address, if the header was present even when the request did not originate from Cloudflare. This made it possible for an attacker to spam login requests or create multiple arbitrary accounts by sending another cf-connecting-ip header every few requests. The issue has been fixed in version 1.11.0.
