# CVE-2026-45052: OpenAM Pre-auth User Profile Tampering via Anonymous SOAP Authn in Liberty IDPP/Discovery Endpoints

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.8% , percentile 55: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 55% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.openidentityplatform.openam:openam-federation-library (Maven) <= 16.0.6, fixed in 16.1.1 . Check your lockfile, including transitive dependencies.

## What it is

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the Liberty Web Services SOAP receiver permits unauthenticated remote requests to write persistent entries through SOAPReceiver and DiscoveryService into a user's Liberty Discovery store and the shared root-realm Discovery branch. The server-side handlers bypass requester LDAP and identity ACLs, and the global path uses an internal administrative token. Deployments that consume Liberty discovery data can subsequently use manipulated service-routing or security-mechanism records. This issue is fixed in version 16.1.1.

## Affected packages

- Maven `org.openidentityplatform.openam:openam-federation-library` <= 16.0.6 → fixed: 16.1.1

## Affected products (CVE record)

- OpenIdentityPlatform OpenAM: < 16.1.1

## Severity

- GitHub_M CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:L/SA:N`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:L/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.77% probability of exploitation activity in the next 30 days; percentile 55.
