Snipe-IT before 8.7.1 fails to validate the length of the note field in the POST /account/accept/{acceptance} endpoint, allowing authenticated users to submit unbounded input that reaches synchronous CommonMark rendering. Attackers can submit large note values to exhaust PHP worker CPU and cause denial of service through resource exhaustion in the markdown parsing pipeline.

AnalysisAI
Denial of service in Snipe-IT before 8.7.1 allows authenticated users to exhaust PHP worker CPU by submitting arbitrarily large values in the note field of the POST /account/accept/{acceptance} endpoint. The unbounded input is passed directly to synchronous CommonMark markdown rendering during acceptance notification email generation, consuming worker CPU proportional to input size on every request. …

Vulnerability AssessmentAI
| Exploitation | The attacker must hold a valid authenticated Snipe-IT user account (PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 7.1 with VA:H accurately reflects a meaningful but bounded availability threat. … 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 8.7.1, which includes two coordinated fixes: a server-side validation rule capping the note field at 1,000 characters in AcceptanceController.php, and an upgrade of league/commonmark to ^2.9.0, identified in the commit as the primary fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all Snipe-IT deployments and verify versions; identify which systems run versions prior to 8.7.1 and review current user access (employees, contractors, service accounts). …
