Is this vulnerability remotely exploitable?

Yes. As long as the WeKan login interface is reachable over the network and LDAP authentication is enabled, a remote attacker can attempt LDAP filter injection through crafted usernames.

What level of access does an attacker need to exploit this?

Only the ability to submit login requests (e.g., access to the login page or related API) is required. No prior authentication is needed; attacker control of the username field is sufficient to attempt exploitation.

What is the safest general fix pattern?

The safest fix is to eliminate manual LDAP filter string construction and instead use vetted LDAP APIs that take raw attribute values and perform necessary escaping. Additionally, enforce strict validation and canonicalization of username inputs before they are used in any directory operation.
