Snipe-IT before 8.7.0 fails to properly sanitize markdown image syntax in note fields, allowing authenticated users to read arbitrary server files and issue server-side HTTP requests. Attackers can submit markdown image syntax in checkout acceptance notes that survive HTML escaping, are expanded by CommonMark parser, and resolved by laravel-mail-auto-embed via file_get_contents or curl, exfiltrating sensitive files like .env containing APP_KEY.
AnalysisAI
Server-side request forgery and arbitrary file read in Snipe-IT before 8.7.0 allow any authenticated user to exfiltrate sensitive server files - including the Laravel .env file containing APP_KEY - by injecting markdown image syntax into checkout acceptance note fields. The injected syntax survives HTML escaping, is expanded by the CommonMark parser, and subsequently resolved by the laravel-mail-auto-embed library via file_get_contents() (local paths) or curl (remote URLs) when email notifications are generated. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Snipe-IT user account with sufficient privilege to submit checkout acceptance notes (PR:L per CVSS 4.0 vector). … 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:H/VI:L/VA:N, SC:H/SI:L/SA:N) scores 8.4, accurately reflecting low-complexity network exploitation by any authenticated low-privilege user with no interaction required and high confidentiality impact on both the vulnerable system and subsequent systems. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Snipe-IT to version 8.7.0 or later, which introduces proper sanitization of markdown image syntax in note fields (vendor advisory: https://github.com/grokability/snipe-it/security/advisories/GHSA-f3vq-g24v-xc2g). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Snipe-IT deployments, document active user accounts, and disable email notifications as an interim control. …
