CVE-2026-84987 · Severity: medium · CVSS 5.4 · Published 2026-11-12

Sharp is a Laravel admin framework used to build administrative interfaces for web applications. An authenticated attacker can bypass the endpoint validation in the autocomplete feature by passing the configured endpoint as a substring, allowing them to make requests to unintended server-side routes. This could enable an attacker to access sensitive functionality or data they should not have permission to reach.

## Technical details

The vulnerability is a server-side request forgery (SSRF) caused by an unanchored regex that validates autocomplete API endpoints. An authenticated attacker can pass the configured endpoint as a substring in a crafted request to bypass the check and target arbitrary server routes. The fix anchors the regex pattern to prevent substring injection attacks.

## Affected products
