## What is CVE-2026-34030?

CVE-2026-34030 is a medium-severity path traversal vulnerability in Wertheim SafeController Software for VAULT ROOMS (Safe Deposit Locker System), published on 15 Jun 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, does not sufficiently validate the branch code when a new branch is created. The branch code is later used in multiple application functions, including filesystem path generation for uploaded files, profile pictures, and settings. An authenticated attacker with the settings_branches_manage privilege can include path traversal sequences in the branch code and influence the final filesystem location used by affected file operations. This can allow files to be stored in unintended locations, subject to service-account write permissions and branch-code length restrictions.

Weakness: CWE-73 (External Control of File Name or Path)

Affected product: Wertheim SafeController Software for VAULT ROOMS (Safe Deposit Locker System). 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.
