# CVE-2025-34060

> 10.0 CRITICAL

## Beschreibung

A PHP objection injection vulnerability exists in the Monero Project’s Laravel-based forum software due to unsafe handling of untrusted input in the /get/image/ endpoint. The application passes a user-supplied link parameter directly to file_get_contents() without validation. MIME type checks using PHP’s finfo can be bypassed via crafted stream filter chains that prepend spoofed headers, allowing access to internal Laravel configuration files. An attacker can extract the APP_KEY from config/app.php, forge encrypted cookies, and trigger unsafe unserialize() calls, leading to reliable remote code execution.

## Schwachstellen-Klasse

- **CWE-20** — Improper Input Validation
  The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
- **CWE-502** — Deserialization of Untrusted Data
  The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
- **CWE-829** — Inclusion of Functionality from Untrusted Control Sphere
  The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.
