CVE-2026-25560: WeKan < 8.19 LDAP Authentication Filter Injection

WeKan versions prior to 8.19 contain an LDAP filter injection vulnerability in LDAP authentication. User-supplied username input is incorporated into LDAP search filters and DN-related values without adequate escaping, allowing an attacker to manipulate LDAP queries during authentication.

Security readout for executives and security teams

Plain-English summary

WeKan versions before 8.19 can mishandle usernames during LDAP login. A remote unauthenticated attacker may alter the LDAP query used for authentication, potentially exposing directory-backed account information. The bundle does not show active exploitation, but the issue is high urgency where WeKan uses LDAP.

Executive priority

Prioritize remediation for internet-accessible or partner-accessible WeKan systems using LDAP. Internal-only systems still warrant prompt update because authentication paths protect organizational identity data.

Technical view

The vulnerability is CWE-90 LDAP filter injection. Username input is placed into LDAP search filters and DN-related values without adequate escaping during authentication. CVSS 4.0 is 8.7 with network access, low complexity, no privileges, and high vulnerable-system confidentiality impact.

Likely exposure

Exposure is most likely for organizations running WeKan before 8.19 with LDAP authentication enabled, especially if the login service is reachable from untrusted networks.

Exploitation context

The source bundle says KEV is false and provides no cited evidence of active exploitation. Risk remains meaningful because exploitation is rated unauthenticated, remote, and low complexity in CVSS.

Researcher notes

The bundle contains a versioning inconsistency: the affected array lists version "0" with defaultStatus "unaffected," while the title and description state versions prior to 8.19 are vulnerable. Treat affected-version validation as important.

Mitigation direction

  • Upgrade WeKan to version 8.19 or later.
  • Review the referenced patch and vendor guidance before production rollout.
  • Restrict external access to WeKan login where operationally possible.
  • Monitor LDAP and WeKan authentication logs for abnormal query or login patterns.

Validation and detection

  • Inventory all WeKan instances and record exact versions.
  • Confirm whether LDAP authentication is enabled on each instance.
  • Verify patched systems are running WeKan 8.19 or later.
  • Review authentication logs for suspicious LDAP lookup behavior.
  • Track vendor and advisory updates for revised affected-version details.

Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')

Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
