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.
Similar SeverityHIGH
Improper link resolution before file access ('link following') in Microsoft Defender allows an authorized attacker to elevate privileges locally.
Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Exchange Server allows an unauthorized attacker to perform spoofing over a network.
An Improper Input Validation in Ivanti EPMM before versions 12.6.1.1, 12.7.0.1, and 12.8.0.1 allows a remotely authenticated user with administrative access to achieve remote code execution.
OpenClaw before 2026.4.22 contains a server-side request forgery vulnerability in the Zalo plugin's sendPhoto function that fails to validate outbound photo URLs through the SSRF guard. Attackers can bypass SSRF protection by providing malicious photo URLs to the Zalo Bot API, enabling unauthorized access to internal resources.
OpenClaw before 2026.4.22 contains an exec allowlist analysis vulnerability allowing shell expansion hiding in unquoted heredoc bodies. Attackers can bypass allowlist validation by embedding shell expansion tokens in heredoc bodies to execute unapproved commands at runtime.
