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.

AFFiNE is an open-source, all-in-one workspace and an operating system. Prior to version 0.25.4, there is a one-click remote code execution vulnerability. This vulnerability can be exploited by embedding a specially crafted affine: URL on a website. An attacker can trigger the vulnerability in two common scenarios: 1/ A victim visits a malicious website controlled by the attacker and the website redirect to the URL automatically, or 2/ A victim clicks on a crafted link embedded on a legitimate website (e.g., in user-generated content). In both cases, the browser invokes AFFiNE custom URL handler, which launches the AFFiNE app and processes the crafted URL. This results in arbitrary code execution on the victim’s machine, without further interaction. This issue has been patched in version 0.25.4.
