## What is CVE-2026-25062?

CVE-2026-25062 is a medium-severity path traversal vulnerability in outline, published on 11 Feb 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Outline is a service that allows for collaborative documentation. Prior to 1.4.0, during the JSON import process, the value of attachments[].key from the imported JSON is passed directly to path.join(rootPath, node.key) and then read using fs.readFile without validation. By embedding path traversal sequences such as ../ or absolute paths, an attacker can read arbitrary files on the server and import them as attachments. This vulnerability is fixed in 1.4.0.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-25062 and fix it if it is affected.

What it is: CVE-2026-25062 is a medium-severity path traversal vulnerability in outline, published on 11 Feb 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-25062 in the wild and no public exploit code.

Affected product: outline. 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.
