What is CVE-2026-25477?

The AFFiNE platform, an open-source workspace solution, contains an Open Redirect vulnerability in versions before 0.26.0. This flaw is attributed to insufficient validation logic within the domain-checking process at the /redirect-proxy endpoint. Attackers can exploit this issue by utilizing specially crafted domains that, while appearing to match an allowed format, actually contain malicious components. Users are encouraged to update to version 0.26.0 or later to mitigate these risks and enhance their security posture.
