## What is CVE-2026-90822?

CVE-2026-90822 is a critical command injection vulnerability in FatPipe Networks IPVPN, published on 17 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

FatPipe MPVPN, WARP, and IPVPN appliances running the end-of-life firmware version 10.1.2r60p100 contain an OS command injection vulnerability in the xtremed daemon. An unauthenticated remote attacker with access to the affected management interface can submit crafted input to the AuthFormServlet endpoint, causing authentication data to be processed by a shell and allowing arbitrary commands to execute as root.

The affected management interface is disabled by default and must be affirmatively enabled by the customer before the endpoint becomes reachable. FatPipe recommends restricting management access to trusted administrative networks and using WAN access control lists to limit access to trusted sources.

Customers running the affected end-of-life firmware can contact FatPipe Support for help confirming their firmware version and upgrading to a current supported release at https://www.fatpipeinc.com/support/support, support@fatpipeinc.com, or +1 800-724-8521 (option 3).

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

What it is: CVE-2026-90822 is a critical command injection vulnerability in FatPipe Networks IPVPN, published on 17 Sep 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-2026-90822 in the wild and no public exploit code.

Affected product: FatPipe Networks IPVPN. 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.
