CVE-2025-66629

HedgeDoc is an open source, real-time, collaborative, markdown notes application. Prior to 1.10.4, some of HedgeDoc's OAuth2 endpoints for social login providers such as Google, GitHub, GitLab, Facebook or Dropbox lack CSRF protection, since they don't send a state parameter and verify the response using this parameter. This vulnerability is fixed in 1.10.4.

Summary		(es) HedgeDoc es una aplicación de notas markdown colaborativa, en tiempo real y de código abierto. Versiones anteriores a 1.10.4, algunos de los endpoints OAuth2 de HedgeDoc para proveedores de inicio de sesión social como Google, GitHub, GitLab, Facebook o Dropbox carecen de protección CSRF, ya que no envían un parámetro de estado y verifican la respuesta usando este parámetro. Esta vulnerabilidad está corregida en 1.10.4.
