## What is CVE-2019-6714?

CVE-2019-6714 is a critical path traversal vulnerability in n/a, published on 17 Mar 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An issue was discovered in BlogEngine.NET through 3.3.6.0. A path traversal and Local File Inclusion vulnerability in PostList.ascx.cs can cause unauthenticated users to load a PostView.ascx component from a potentially untrusted location on the local filesystem. This is especially dangerous if an authenticated user uploads a PostView.ascx file using the file manager utility, which is currently allowed. This results in remote code execution for an authenticated user.

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

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2019-6714 and fix it if it is affected.

What it is: CVE-2019-6714 is a critical path traversal vulnerability in n/a, published on 17 Mar 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-6714 exists.

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.
