What is CVE-2026-88894?

CVE-2026-88894 is Snipe-IT before 8.7.2 Authorization Bypass via Predefined Kit Checkout. The supplied enrichment data classifies it as Access Control mapped to CWE-863 Incorrect Authorization.

Which versions are affected?

Affected product and version evidence is listed in the product table above. Current public advisories should be checked for exact version scope before patch targeting is finalized.

Is there active exploitation?

Active exploitation is not confirmed from current sources for CVE-2026-88894. If exploitation is not confirmed from current sources, teams should document that status and continue monitoring KEV, vendor, and telemetry updates.

No. CVE-2026-88894 is not listed in CISA KEV in the supplied enrichment data. KEV status should be monitored because it can change after initial disclosure or after exploitation becomes publicly confirmed.

Is there a public exploit?

A public PoC is not confirmed from current sources for CVE-2026-88894. Public exploit or PoC availability should raise triage priority, especially for exposed or business-critical systems.

How can defenders detect it?

Start with web/proxy/WAF logs, application logs, network IDS/IPS where available. Look for vulnerability-class behavior, product errors, suspicious authentication events, exploit probes, and abnormal process activity based only on evidence that applies to the affected product.

How should teams prioritize it?

Prioritize CVE-2026-88894 using CVSS 5.4, EPSS 0%, KEV status, public PoC status, and asset exposure. Internet-facing, privileged, or business-critical deployments should be handled first.

Are workarounds available?

The supplied mitigation guidance says to apply vendor patches and restrict external exposure until fixed. Fixed-version evidence is listed in the mitigation section above.

Which threat actors are linked publicly?

No public threat actor linkage is confirmed from current sources. Do not attribute exploitation to a threat actor unless the source evidence explicitly supports that linkage.

What should be done in the next 24 hours?

Identify exposed assets running affected vendor/product/version combinations. Prioritize based on EPSS, PoC availability, and external exposure. Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class. Open remediation tickets with affected assets, owners, evidence status, and detection coverage so decisions are traceable.

CVE-2026-88894

CVE-2026-88894 — Snipe-IT before 8.7.2 Authorization Bypass via Predefined Kit Checkout

Snipe-IT's predefined kit checkout path does not enforce Full Multiple Company Support (FMCS) tenant isolation on the checkout target. Unlike the single, bulk, API, accessory, license and consumable checkout paths, App\Services\PredefinedKitCheckoutService never calls $item->canCheckoutTo($target); it only performs the actor-vs-item policy check and an availability check before persisting the checkout. With FMCS enabled, a non-superuser who belongs to at least two companies and holds the assets.checkout permission can POST to /kits/{kit}/checkout with a user_id belonging only to company B and have a company-A asset (and likewise kit licenses, consumables and accessories) assigned to that user, bypassing the company-mismatch check that blocks the same operation on every other checkout path. The issue is fixed in Snipe-IT 8.7.2; it was runtime-verified on v8.6.3 and code-inspected on v8.7.1, and the affected service has lacked the check since 2019, so earlier FMCS deployments are likely also affected.

Mitigation: Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.

Answered from this record1

What should defenders know first?

CVE-2026-88894 is Snipe-IT before 8.7.2 Authorization Bypass via Predefined Kit Checkout, a medium vulnerability affecting snipe-it from grokability. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-88894. Public exploit evidence is: A public PoC is not confirmed from current sources for CVE-2026-88894. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 5.4 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
