## What is CVE-2026-61749?

CVE-2026-61749 is a medium-severity server-side request forgery vulnerability in InvenTree, published on 21 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, privileged staff users who can author report or label templates can cause WeasyPrint report rendering to retrieve attacker-selected resources through the HTTP and HTTPS URL schemes or the local file URI scheme. The HTML(string=html).write_pdf() path does not provide a restricted url_fetcher, and attach_to_model=True stores the original generated PDF before later processing, allowing fetched local files or internal HTTP response bodies to be recovered from embedded attachments. This enables full-read server-side request forgery, arbitrary local file disclosure including application credentials, and possible compromise of a superuser account. This issue is fixed in version 1.4.0.

Weakness: CWE-918 (Server-Side Request Forgery), CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

Check this codebase for CVE-2026-61749 and fix it if it is affected.

What it is: CVE-2026-61749 is a medium-severity server-side request forgery vulnerability in InvenTree, published on 21 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-61749 in the wild and no public exploit code.

Affected product: InvenTree. 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.
