## What is CVE-2025-0672?

CVE-2025-0672 is a low-severity authentication bypass vulnerability in Wso2 Identity Server, published on 23 Sep 2025. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

An authentication bypass vulnerability exists in multiple WSO2 products when FIDO authentication is enabled. When a user account is deleted, the system does not automatically remove associated FIDO registration data. If a new user account is later created using the same username, the system may associate the new account with the previously registered FIDO device.

This flaw may allow a previously deleted user to authenticate using their FIDO credentials and impersonate the newly created user, resulting in unauthorized access. The vulnerability applies only to deployments that utilize FIDO-based authentication.

Weakness: CWE-287 (Improper Authentication)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-0672 and fix it if it is affected.

What it is: CVE-2025-0672 is a low-severity authentication bypass vulnerability in Wso2 Identity Server, published on 23 Sep 2025. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-0672 in the wild and no public exploit code.

Affected product: Wso2 Identity Server. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
