CVE-2026-25227: authentik affected by Remote Code Execution via Context Key Injection in PropertyMapping Test Endpoint

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.89% (FIRST EPSS); higher than 59.3% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

authentik is an open-source identity provider. From 2021.3.1 to before 2025.8.6, 2025.10.4, and 2025.12.4, when using delegated permissions, a User that has the permission Can view * Property Mapping or Can view Expression Policy is able to execute arbitrary code within the authentik server container through the test endpoint, which is intended to preview how a property mapping/policy works. authentik 2025.8.6, 2025.10.4, and 2025.12.4 fix this issue.
