## What is CVE-2026-55694?

CVE-2026-55694 is a high-severity missing authorization vulnerability in Snipeitapp Snipe-It, published on 19 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Snipe-IT is an IT asset/license management system. Prior to 8.6.3, a restricted user can request /api/v1/users/{target_id}/eulas to obtain another user's randomized EULA filename and then download the signed file through /account/stored-eula-file/{filename}. The primary /stored-eula-file/{filename} route correctly denies access, but app/Http/Controllers/ProfileController.php and app/Http/Controllers/Api/UsersController.php do not consistently enforce ownership and target-user authorization. This issue is fixed in version 8.6.3.

Weakness: CWE-639 (Authorization Bypass Through User-Controlled Key)

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.
