The Kalrav AI Agent plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the kalrav_upload_file AJAX action in all versions up to, and including, 2.3.3. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
MeetingHub developed by HAMASTAR Technology has an Arbitrary File Upload vulnerability, allowing unauthenticated remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.
HCL AION is affected by an Unrestricted File Upload vulnerability. This can allow malicious file uploads, potentially resulting in unauthorized code execution or system compromise.
Livewire Filemanager, commonly used in Laravel applications, contains LivewireFilemanagerComponent.php, which does not perform file type and MIME validation, allowing for RCE through upload of a malicious php file that can then be executed via the /storage/ URL if a commonly performed setup process within Laravel applications has been completed.
VIAVIWEB Wallpaper Admin 1.0 contains an unauthenticated remote code execution vulnerability in the image upload functionality. Attackers can upload a malicious PHP file through the add_gallery_image.php endpoint to execute arbitrary code on the server.

ipmi-oem in FreeIPMI before 1.16.18 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI) and remote power control (the ipmipower command). The ipmi-oem client command implements a set of a IPMI OEM commands for specific hardware vendors. If a user has supported hardware, they may wish to use the ipmi-oem command to send a request to a server to retrieve specific information. Two subcommands "ipmi-oem dell get-active-directory-config" and "ipmi-oem fujitsu get-sel-entry-long-text" were found to have exploitable buffer overflows on response messages.

A vulnerability was detected in SourceCodester Online Food Ordering System 2.0. Affected by this issue is the function include of the file /index.php. The manipulation of the argument page results in file inclusion. The attack can be launched remotely. The exploit is now public and may be used.
alf.io is an open source ticket reservation system for conferences, trade shows, workshops, and meetups. Prior to version 2.0-M5-2606, a sandbox escape vulnerability in the alf.io extension script engine allows an authenticated administrator to execute arbitrary operating system commands on the server. The extension system is intended to execute restricted JavaScript in a sandboxed Rhino environment; however, a combination of an unguarded injected Java object (`returnClass`) and an incomplete AST blocklist allows the sandbox to be fully escaped using Java reflection without triggering any validation errors. Version 2.0-M5-2606 patches the issue.
