DescriptionCVE.org

Snipe-IT is an IT asset/license management system. Prior to 8.6.0, POST /account/request/{itemType}/{itemId}/{cancel_by_admin?}/{requestingUser?} accepts cancel_by_admin as a URL path segment without sufficient authorization, allowing an authenticated user to supply a victim user ID and silently cancel that user’s pending asset requests. This issue is fixed in version 8.6.0.

medium.com CVE-2026-55476: IDOR in Snipe-IT Allows Any User to Cancel Asset Requests as Admin Jul 02, 2026

AnalysisAI

Missing authorization on Snipe-IT's asset request cancellation endpoint prior to version 8.6.0 allows any authenticated low-privileged user to cancel another user's pending asset requests by supplying a victim's user ID in the URL path segment. The cancel_by_admin path parameter is accepted without server-side privilege verification, constituting a CWE-862 (Missing Authorization) flaw - effectively a broken object-level authorization issue on an administrative action. …

Hypothetical attack flow derived from CVE metadata

Access
Authenticate as low-privileged Snipe-IT user

Vulnerability AssessmentAI

Exploitation Exploitation requires an active, authenticated Snipe-IT session with at minimum a low-privileged user account (CVSS PR:L confirmed). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N) indicates network-exploitable with low complexity by any authenticated user, but impact is narrowly scoped to low integrity with no confidentiality or availability consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated low-privileged employee logs into Snipe-IT, enumerates a colleague's user ID and a pending asset request's itemType and itemId (both derivable from application UI or API responses), then sends a crafted POST to /account/request/{itemType}/{itemId}/1/{victimUserId} - embedding the cancel_by_admin flag and victim ID in the URL. The server processes the cancellation without verifying the caller's administrative authority, silently invalidating the victim's pending request. …
Remediation Upgrade Snipe-IT to version 8.6.0, which resolves the missing authorization check on the cancel_by_admin URL path parameter. … Detailed patch versions, workarounds, and compensating controls in full report.
