## What is CVE-2025-3026?

CVE-2025-3026 is a medium-severity vulnerability in PrimeKey Solutions AB EJBCA, published on 31 Mar 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The vulnerability exists in the EJBCA service, version 8.0 Enterprise. Not tested in higher versions. By modifying the ‘Host’ header in an HTTP request, it is possible to manipulate the generated links and thus redirect the client to a different base URL.  In this way, an attacker could insert his own server for the client to send HTTP requests, provided he succeeds in exploiting it.

Weakness: CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component)

Affected packages and fixed versions:
- ejbca (Bitnami): affected from 8.0.0; fixed in 9.1.0

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.
