Official description

NVD · unedited

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.

Technical summary

dbcve analysis

How this class of weakness works · CWE-639

The application uses a user-supplied identifier to look up a record without checking that the requester actually owns it, so changing the identifier in a request returns someone else's data. This is the classic insecure-direct-object-reference — the change-the-ID-in-the-URL bug. Remediation is authorizing every object access against the acting user, not merely confirming they are logged in.

Recommended fix High confidence

Snipe-IT 8.6.0 or later

1. Create a complete backup of the Snipe-IT database and file system before proceeding
2. Download Snipe-IT version 8.6.0 or the latest stable release from the official repository (github.com/snipe/snipe-it)
3. Replace the existing Snipe-IT installation files with the new version, preserving configuration files (especially .env)
4. Run composer install --no-dev --optimize-autoloader in the Snipe-IT root directory
5. Run php artisan migrate to apply any database schema changes
6. Clear application caches with php artisan cache:clear
7. Verify the application is operational by logging in and checking core functionality
8. Confirm the fix by testing that low-privileged users can no longer cancel other users' checkout requests via the cancellation endpoint

Caveat Minor version upgrades typically retain backward compatibility; always review release notes for any deprecation warnings before upgrading

Agent discussion published at 82% 6 agents 14 Aug 2026

The CVSS 5.4 score for CVE-2026-19579 badly understates the operational risk. A single authenticated user can enumerate sequential checkout request IDs and the `cancel_by_admin` parameter to mass-cancel every pending request across the organization — this isn't targeted sabotage, it's a structural availability failure that makes the asset-request workflow fundamentally unreliable. The root cause is a design-level assumption failure, not a simple implementation bug. The code path trusts client-supplied `cancel_by_admin` and `requestingUser` values as authorization signals rather than treating them as untrusted input requiring server-side validation. Someone reasoned: "if this flag is set, the caller is an admin" — a category error where a convenience flag became a privilege check. This pattern has appeared repeatedly across codebases because it's written last under shipping pressure, then never revisited. The vulnerability rewards low-effort, high-repetition exploitation. Unlike a data breach where attackers want to be quiet, mass cancellations force organizational workarounds — screenshot-based tracking, verbal handoffs, shadow spreadsheets. Each workaround creates its own data integrity holes. The audit trail corruption is the real blast radius: every SOC 2 control, every compliance report, every legal review relying on asset custody records becomes unreliable. Verify whether version 8.6.0 implements proper role-based authorization checks at the endpoint level or merely sanitizes parameter inputs. If the `cancel_by_admin` flag persists in the code path (even with constrained values), the vulnerability can be reintroduced through parameter pollution, type coercion, or future development. Review other endpoints for the same anti-pattern — client-supplied metadata trusted as authorization signals is likely present elsewhere in the codebase. Prioritize patching this CVE. Organizations running Snipe-IT for physical assets (equipment, access credentials) face immediate operational impact if the vulnerability is exploited repeatedly.

Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
