CVE-2026-6266: Aap-controller: aap-gateway: account hijacking and unauthorized access via unverified email linking

HighCVSS 8.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 0.39% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: access.redhat.com/downloads/content/package-browser automation-controller 4.6.28, 4.7.11; access.redhat.com/downloads/content/package-browser automation-gateway 2.5.20260422, 2.6.20260422; github.com/ansible/django-ansible-base django-ansible-base 2.5.20260422, 2.6.20260422.

Low priority for now. Upgrade to access.redhat.com/downloads/content/package-browser automation-controller 4.6.28, 4.7.11; access.redhat.com/downloads/content/package-browser automation-gateway 2.5.20260422, 2.6.20260422; github.com/ansible/django-ansible-base django-ansible-base 2.5.20260422, 2.6.20260422 or later.

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

A flaw was found in the AAP gateway. The user auto-link strategy, introduced in AAP 2.6, automatically links an external Identity Provider (IDP) identity to an existing AAP user account based on email matching without verifying email ownership. This allows a remote attacker to potentially hijack a victim's account or gain unauthorized access to other accounts, including administrative accounts, by manipulating the IDP-provided email.
