2026-05-14 - Kanidm 1.10.3 - Patch

• Resolve an incorrect internal query that can prevent upgrades from 1.9 to 1.10 in rare circumstances
• Resolve a unixd resolver deadlock that can occur during rare data conflict conditions

2026-05-14 - Kanidm 1.10.2 - Patch (Security: CRITICAL)

This update resolves 1 security issues which allows privilege escalation to be performed by any authenticated user. We have no evidence that this is in active exploitation.

• Security - Critical: Any authenticated user is able to modify the attributes of any entry they have read permissions over. This is due to a logic flaw in modification access control application. Since all authenticated users are able to read all groups and group members, any authenticated user is able to add themself to any privileged group resulting in complete compromise of the servers security boundaries.
• Revert client_id header in JWTs used in OAuth2/OIDC - this is due to incorrect behaviour of some OAuth2 clients rejecting content of the protected header.
• Disable OIDC prompt=login - a number of issues were identified in this flow that are unable to be trivially fixed until a future release.
• Remove debug-symbols from release builds to reduce container image sizes.

Thanks to @kmq for the initial security report, and the Kanidm team for identifying the extended risk posed from the initial report.

2026-05-07 - Kanidm 1.10.1 - Patch

• Resolve an incorrect javascript encoding of some fields that prevents new Webauthn enrolments from completing
• Correct incorrect text in TOTP CLI credential updates

2026-05-01 - Kanidm 1.10.0

This is the latest stable release of the Kanidm Identity Management project. Every release is the combined effort of our
community and we appreciate their invaluable contributions, comments, questions, feedback and support.

You should review our support documentation as this may have important effects on your distribution or upgrades in
future.

1.10.0 Important Changes

• OpenSSL is no longer required as a dependency. All cryptographic paths have been replaced by RustCrypto or Rustls using aws-lc-rs.
• Kanidm-unixd now supports bind mounts as an alternative to symlinks for home mapping.
• Account recovery can be enabled as a feature allowing a user to prove knowledge of their own email, and then have a credential reset email sent to them.
  • Administrators can also trigger account recovery emails to be sent to users.

1.10.0 Release Highlights

• Security - High: SCIM Filters did not contain a bound on their parsing depth allowing stack exhaustion to occur leading to Denial of Service by an unauthenticated user
• Security - High: LDAP Filters did not contain a bound on their parsing depth allowing stack exhaustion to occur leading to Denial of Service by an unauthenticated user
• Security - Moderate: PNG Image validation did not correctly handle short images allowing a panic to occur in a worker thread. This may lead to system instability over time
• Security - Low: HTML injection via user DisplayName in Passkey enrolment dialogs. This allows an admin to execute JS in the context of a users browser. Since the admin already can reset the users credentials, the impact of this is minimal.
• Security - Low: non-constant time comparison of OAuth2 client secret may allow a remote attacker to remotely recovery the bytes of the secret. Due to the length of the secret (48 chars) this is infeasible practically.
• Security - Low: incorrect handling of origin validation in Webauthn-RS allowed a malicious domain to collide with a valid one (badexample.com would match with example.com). This is mitigated by browsers detecting the forgery and preventing the authentication from proceeding.
