CVE-2026-123537: OpenAM before 16.1.4 SSRF via UMA Scope Description URLs
Noroxi assessment
Priority: Monitor (action score 21/100)
- 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: 0.20% (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: OpenIdentityPlatform OpenAM 16.1.4.
Low priority for now. Upgrade to OpenIdentityPlatform OpenAM 16.1.4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
OpenAM before 16.1.4 contains a server-side request forgery vulnerability that allows parties registering UMA resource sets to trigger internal requests through unvalidated scope description URLs. Attackers can register resource sets with scope URLs pointing to internal hosts or cloud metadata endpoints, which OpenAM fetches when sending pending-request notification emails, enabling internal network probing.
