## What is CVE-2026-19579?

CVE-2026-19579 is a medium-severity missing authorization vulnerability in Snipeitapp Snipe-It, published on 11 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Snipe-IT before 8.6.0 contains an authorization bypass (insecure direct object reference) in the asset checkout-request cancellation endpoint. The cancel_by_admin and requestingUser values are read from user-controlled URL path segments and used without a server-side authorization check, so any authenticated, low-privileged user can supply a non-empty cancel_by_admin value to bypass the request-ownership check and cancel another user's pending checkout request. Because asset and user identifiers are sequential integers, an attacker can enumerate them to cancel every pending checkout request, disrupting the asset-request workflow. This is fixed in Snipe-IT 8.6.0.

Weakness: CWE-807 (Reliance on Untrusted Inputs in a Security Decision), CWE-639 (Authorization Bypass Through User-Controlled Key)

What it is: CVE-2026-19579 is a medium-severity missing authorization vulnerability in Snipeitapp Snipe-It, published on 11 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-19579 in the wild and no public exploit code.

Affected product: Snipeitapp Snipe-It. 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.
