Jirafeau project — Vulnerabilities & Security Advisories 3

Jirafeau is a lightweight PHP-based file upload service designed for simple file sharing without requiring a database. Historically, the project has been vulnerable to multiple remote code execution (RCE) flaws, cross-site scripting (XSS) vulnerabilities, and privilege escalation issues due to insufficient input validation and insecure file handling. Notable security characteristics include its minimal architecture, which while reducing complexity, has consistently exposed attack vectors through improper sanitization of user-supplied data. The project's three recorded CVEs highlight persistent security challenges, particularly in how file permissions and access controls are implemented, making it essential for users to maintain current versions and implement additional security layers.
