Automated description summarized from trusted sources.

CVE-2025-56399 is a Remote Code Execution (RCE) vulnerability found in versions 3.3.1 and earlier of the `alexusmai/laravel-file-manager` package. This flaw allows an authenticated attacker to execute arbitrary PHP code on the server. The vulnerability is exploited by uploading a crafted file, such as one with a `.png` extension containing PHP code, through the file manager interface. Despite client-side validation potentially indicating a failed upload, the file is still saved on the server. The attacker can then leverage the package's rename API to change the file's extension to `.php`, leading to the execution of the embedded code when accessed via a public URL.
