## What is CVE-2026-34883?

CVE-2026-34883 is a medium-severity path traversal vulnerability in n/a, published on 19 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An issue was discovered in the Portrait Dell Color Management application before 3.7.0 for Dell monitors. On Windows, a symbolic link vulnerability allows a local low-privileged user to escalate privileges to Administrator. During installation, the software writes the file CCFLFamily_07Feb11.edr to C:\ProgramData\Portrait Displays\CW\data\i1D3\ while running with elevated privileges. Because the installer does not properly validate symbolic links or reparse points at the destination path, an attacker can create a malicious link that redirects the write operation to an arbitrary system location, enabling arbitrary file creation or overwrite with elevated privileges.

Weakness: CWE-59 (Improper Link Resolution Before File Access)

Check this codebase for CVE-2026-34883 and fix it if it is affected.

What it is: CVE-2026-34883 is a medium-severity path traversal vulnerability in n/a, published on 19 May 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-2026-34883 in the wild and no public exploit code.

Affected product: n/a. 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.
