## What is CVE-2026-25701?

CVE-2026-25701 is a high-severity path traversal vulnerability in openSUSE sdbootutil, published on 25 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An Insecure Temporary File vulnerability in openSUSE sdbootutil allows local users to pre-create a directory to achieve various effects like:
  *  gain access to possible private information found in /var/lib/pcrlock.d
  *  manipulate the data backed up in /tmp/pcrlock.d.bak, therefore violating the integrity of the data should it be restored.
  *   overwrite protected system files with data from /var/lib/pcrlock.d by placing symlinks to existing files in the directory tree in /tmp/pcrlock.d.bak.

This issue affects sdbootutil: from ? before 5880246d3a02642dc68f5c8cb474bf63cdb56bca.

Weakness: CWE-377 (DEPRECATED: Insecure Temporary File)

Check this codebase for CVE-2026-25701 and fix it if it is affected.

What it is: CVE-2026-25701 is a high-severity path traversal vulnerability in openSUSE sdbootutil, published on 25 Feb 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-2026-25701 in the wild and no public exploit code.

Affected product: openSUSE sdbootutil. 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.
