Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A PHP object injection vulnerability exists in Monero Project's Laravel forum software where the /get/image endpoint passes a user-supplied link parameter directly to file_get_contents() without validation. Attackers can bypass MIME type checks using finfo via crafted stream filter chains to prepend spoofed headers, enabling access to internal Laravel configuration files, extraction of APP_KEY, cookie forgery, and unsafe unserialize() calls resulting in reliable RCE.

MitigationImmediately disable or restrict the /get/image endpoint, implement strict allowlist-based input validation for the link parameter, rotate the exposed APP_KEY, and audit similar endpoints for comparable unsafe file operations.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed forum software version
    Locate the composer.json or version file in the Monero forum application directory, or run a command like 'grep -r "version" .' in the application root to find version information.
    Affected if The installed version does not include the security patch for CVE-2025-34060 (no fixed version specified; compare to any available updates).
  2. Verify the /get/image endpoint exists
    Check if the route is defined in the application's routes/web.php or routes/api.php file, and confirm the controller method exists in the codebase.
    Affected if The /get/image endpoint is present and exposed in the application routing configuration.
  3. Confirm the vulnerable parameter handling in code
    Search the source code for the /get/image controller method and verify it uses file_get_contents() with a user-supplied 'link' parameter without proper validation; grep for 'file_get_contents' and 'link' in the relevant controller.
    Affected if The code passes the 'link' parameter directly to file_get_contents() without sanitization or allowlist validation.
  4. Check if the finfo MIME type check is present
    Review the /get/image endpoint code to see if it uses finfo_file() or similar for MIME detection, and verify whether stream filter chain bypasses are mitigated.
    Affected if The code relies solely on finfo for MIME verification without additional validation to prevent stream filter manipulation.
  5. Inspect Laravel configuration exposure risk
    Verify that internal Laravel configuration files (config/app.php, .env) are not accessible via the vulnerable endpoint by testing if the endpoint can read these files when given a path to them.
    Affected if The application allows reading internal Laravel configuration files through the link parameter, exposing APP_KEY or other secrets.

You are affected if the Monero Laravel forum software has the /get/image endpoint enabled, uses a version with the vulnerable file_get_contents() implementation on the link parameter, and does not validate or restrict the parameter to prevent access to internal files.
