CVE-2026-55694: Snipe-IT: Chained Information Disclosure and IDOR Leads to Full EULA File Takeover
Noroxi assessment
Priority: Monitor (action score 28/100)
- 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: 0.28% (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, a restricted user can request /api/v1/users/{target_id}/eulas to obtain another user's randomized EULA filename and then download the signed file through /account/stored-eula-file/{filename}. The primary /stored-eula-file/{filename} route correctly denies access, but app/Http/Controllers/ProfileController.php and app/Http/Controllers/Api/UsersController.php do not consistently enforce ownership and target-user authorization. This issue is fixed in version 8.6.3.
