Description

An LDAP injection vulnerability in the LDAP Certificate repository of the XKMS server in Apache CXF may allow an attacker to retrieve arbitrary certificates from the repository.  Users are recommended to upgrade to versions 4.2.1, 4.1.6 or 3.6.11, which fix this issue.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.cxf.services.xkms:cxf-services-xkms-x509-repo-ldap to 4.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pg32-686q-qh6x is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
