## What is CVE-2026-46581?

CVE-2026-46581 is a high-severity server-side request forgery vulnerability in Eclipse Mojarra, published on 5 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Eclipse Mojarra versions 2.3 and following, URL handing in `DefaultFaceletFactory` does not properly sanitize and/or block remote URLs, allowing an attacker to specify a URL to a remote Facelet which will be included and processed as part of the normal request, with the privileges of the target server. This could allow access to restricted files such as `WEB-INF/web.xml` or `/etc/passwd`.

What it is: CVE-2026-46581 is a high-severity server-side request forgery vulnerability in Eclipse Mojarra, published on 5 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-46581 in the wild and no public exploit code.

Affected product: Eclipse Mojarra. 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.
