CVE-2026-55703: Snipe-IT: Maintenance Record Disclosure via Missing Authorization on GET

Noroxi assessment

Priority: Monitor (action score 17/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.34% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: grokability snipe-it 8.6.3.

Low priority for now. Upgrade to grokability snipe-it 8.6.3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Snipe-IT is an IT asset/license management system. Prior to 8.6.3, any activated account can request /maintenances/{id} and read maintenance records for assets in the same company without asset or maintenance permission. app/Http/Controllers/MaintenancesController.php show() renders the record without authorize(), while company-scoped route-model binding only prevents access to other companies. Disclosed fields include asset tags, suppliers, purchase costs, notes, and dates. This issue is fixed in version 8.6.3.
