## What is CVE-2026-47687?

CVE-2026-47687 is a high-severity cross-site scripting vulnerability in fogproject, published on 21 Jul 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the `selectForm()` helper in `fogpage.class.php` renders `<option>` labels using raw, unescaped user input. An unauthenticated attacker who knows any registered host's MAC address can POST a malicious `sysproduct` value to `/service/inventory.php`, which is stored in the database. When an administrator opens Reports > Inventory, the payload breaks out of the `<option>` element and executes arbitrary JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2026-47687 and fix it if it is affected.

What it is: CVE-2026-47687 is a high-severity cross-site scripting vulnerability in fogproject, published on 21 Jul 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-47687 exists.

Affected product: fogproject. 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.
