CVE-2026-86773 — Incorrect Authorization in Snipeitapp Snipe-it
Snipe-IT through version 8.6.3 fails to perform object-level authorization in the updateLicense, updateConsumable, updateAccessory, and updateModel endpoints and in the storeModel endpoint for Predefined Kits. The existing check authorizes only the parent Predefined Kit (update on PredefinedKit) and not the child object being attached. As a result, an authenticated user holding only the kits.edit permission can attach a License, Consumable, Accessory, or Asset Model that they are otherwise denied (HTTP 403) from reading directly to a Predefined Kit, and the kit relation index then discloses the attached object's name back to that low-privilege user. This is the update-path and storeModel counterpart to CVE-2026-55478, which fixed only the storeLicense, storeConsumable, and storeAccessory methods in 8.6.2. Note that updateModel was code-vulnerable in 8.6.3 but not reachable in practice because a route-name typo bound the route to a nonexistent controller method, causing HTTP 500 responses. The issue is fixed in Snipe-IT 8.7.0.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Snipeitapp Snipe-it).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
Affected scope
Vendor, product and versions as the sources word them.

Every base score collected
Sources score independently and may disagree; each row says who scored it and under which version.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N (score shown at the top: disclosure@vulncheck.com) Weakness MITRE
Weakness class according to MITRE’s CWE catalog.
Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Audit administrative actions and access to resources outside each user’s normal pattern.
