CVE-2026-58489— HedgeDoc 跨站请求伪造漏洞

HedgeDoc: CSRF in GitHub Gist export callback

HedgeDoc is an open source, real-time collaborative markdown notes application. Prior to 1.11.0, the GitHub Gist export flow created an OAuth2  state  value but only checked that it was present rather than validating it against the value expected for the user's session. Because the state was not properly validated, an attacker could forge a callback URL containing their own valid GitHub OAuth code. When processing the callback, HedgeDoc used the victim's logged-in session to select which note to export, but the attacker's authorization code to determine which GitHub account received it. As a result, a logged-in victim who clicked a crafted link could export their own private, protected, or limited note directly into a Gist controlled by the attacker. This issue has been fixed in version 1.11.0.

HedgeDoc 跨站请求伪造漏洞

HedgeDoc是HedgeDoc团队开源的一个基于Javascript的Markdown文档实时编辑分享平台。 HedgeDoc 1.11.0版本之前存在跨站请求伪造漏洞，该漏洞源于GitHub Gist导出流程中的OAuth2状态值未正确验证，可能导致登录用户点击特制链接后将私有笔记导出到攻击者控制的Gist中。
