CVE-2024-30248
📋 TL;DR
Piccolo Admin versions before 1.3.2 allow SVG file uploads by default, which can contain malicious scripts. When an attacker uploads a crafted SVG file, it can execute arbitrary JavaScript in the admin panel context, potentially compromising the admin interface. This affects all Piccolo Admin deployments using default configurations.

⚠️ Risk & Real-World Impact
Worst Case
An attacker gains full administrative access to the Piccolo Admin interface, allowing data manipulation, privilege escalation, and potential server compromise through subsequent attacks.
Likely Case
Attackers upload malicious SVG files to execute JavaScript in admin sessions, potentially stealing session tokens, manipulating data, or performing actions as authenticated users.
If Mitigated
With proper input validation and file type restrictions, SVG uploads are blocked or sanitized, preventing script execution while maintaining legitimate SVG functionality.
🎯 Exploit Status
Exploitation requires the ability to upload files to the admin interface, which typically requires some level of access. The vulnerability is straightforward to exploit once access is obtained.
