How do I detect CVE-2026-123545 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2026-123545 if there is no patch (or I can't update yet)?

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.

Is CVE-2026-123545 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-123545 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

OpenAM from 14.5.1 before 16.1.4 contains a cross-site request forgery vulnerability in the OAuth 2.0 device authorization flow that allows attackers to approve device codes when consent is skipped for implied-consent clients. Attackers can start a device authorization and lure a logged-in user to a crafted page, obtaining access and ID tokens to call APIs as that user.
