## What is CVE-2026-102113?

CVE-2026-102113 is a high-severity vulnerability in Accellion Kiteworks, published on 30 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root. A privileged routine did not safely handle a filesystem path that the lower-privileged account could influence, allowing the attacker to cause a root-owned operation to run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.

Weakness: CWE-59 (Improper Link Resolution Before File Access), CWE-269 (Improper Privilege Management)

What it is: CVE-2026-102113 is a high-severity vulnerability in Accellion Kiteworks, published on 30 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-102113 in the wild and no public exploit code.

Affected product: Accellion Kiteworks. 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.
