Laravel Framework through 8.70.2 does not sufficiently block the upload of executable PHP content because Illuminate/Validation/Concerns/ValidatesAttributes.php lacks a check for .phar files, which are handled as application/x-httpd-php on systems based on Debian. NOTE: this CVE Record is for Laravel Framework, and is unrelated to any reports concerning incorrectly written user applications for image upload.

GHSA-364w-9g92-3grqWithdrawn: Laravel Framework does not sufficiently block the upload of executable PHP content.2021-11-16ghsa · osvUS
# Withdrawn This advisory has been withdrawn after the maintainers of Laravel noted this issue is not a security vulnerability with Laravel itself, but rather a userland issue. ## Original CVE based description Laravel Framework through 8.70.2 does not sufficiently block the upload of executable PHP content because Illuminate/Validation/Concerns/ValidatesAttributes.php lacks a check for .phar files, which are handled as application/x-httpd-php on systems based on Debian. In some use cases, this may be related to file-type validation for image upload (e.g., differences between getClientOriginalExtension and other approaches).
