Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

Description

AFFiNE is an open-source, all-in-one workspace and an operating system. Prior to version 0.26.0, there is an Open Redirect vulnerability located at the /redirect-proxy endpoint. The flaw exists in the domain validation logic, where an improperly anchored Regular Expression allows an attacker to bypass the whitelist by using malicious domains that end with a trusted string. This issue has been patched in version 0.26.0.
