What is CVE-2026-63653?

Group-Office, an enterprise customer relationship management and groupware tool, has a vulnerability in its Bookmark module. Prior to version 26.0.37, the description() action of the bookmarks controller allowed an attacker to send a maliciously crafted URL parameter directly. This parameter was used without any validation in the HttpClient request, posing a risk of Server-Side Request Forgery (SSRF). By exploiting this flaw, an attacker could potentially send requests to internal servers, thus compromising the security of the system. This vulnerability has been addressed in the updated version 26.0.37 with appropriate patches.
