CVE-2025-67288 1 Umbraco 1 Umbraco Cms 2026-07-08 N/A 10.0 CRITICAL
An arbitrary file upload vulnerability in Umbraco CMS v16.3.3 allows attackers to execute arbitrary code by uploading a crafted PDF file. NOTE: this is disputed by the Supplier because the responsibility for file validation (as shown in the documentation) belongs to the system administrator who is implementing Umbraco CMS in their environment, not to Umbraco CMS itself. The Supplier also states that PDF JavaScript runs in a completely isolated sandbox, not the browser's DOM context, which means that privilege boundaries would not be crossed, a related issue to CVE-2023-49279.
CVE-2026-9182 3 Esri, Linux, Microsoft 3 Arcgis Server, Linux Kernel, Windows 2026-07-08 N/A 9.8 CRITICAL
Esri ArcGIS Server contains an unrestricted file upload vulnerability. An unauthenticated attacker could exploit this issue by uploading a crafted file to the affected endpoint. Successful exploitation could allow arbitrary file upload, potentially allowing for other attacks. This issue impacts all versions of ArcGIS Server on Windows and Linux 12.0 and prior. This issue does not impact ArcGIS Enterprise for Kubernetes.
CVE-2026-58480 2026-07-08 N/A 9.8 CRITICAL
Blocksy Companion Pro plugin for WordPress before 2.1.47 contains an unauthenticated arbitrary file upload vulnerability that allows attackers to upload executable files by bypassing extension validation in the save_attachments function exposed through the Advanced Reviews feature. Attackers can exploit the Custom Fonts extension's flawed strpos() substring check by uploading double-extension filenames such as shell.woff2.php, causing the validation to pass on the substring match while the web server executes the file as PHP, achieving remote code execution.
CVE-2026-23697 2026-07-08 N/A 8.8 HIGH
Vtiger CRM before 8.4.0 contains an authenticated file upload vulnerability that allows low-privileged users to achieve remote code execution by uploading a .phar file containing arbitrary PHP code through the Documents module, bypassing the extension denylist in config.inc.php which omits the .phar extension. The uploaded file is stored with its original .phar extension under the web-accessible storage directory, and a misconfigured .htaccess using Apache 2.2 syntax is silently ignored on Apache 2.4 deployments, allowing unauthenticated HTTP requests to directly execute the uploaded PHP payload.
CVE-2026-23698 2026-07-08 N/A 7.2 HIGH
Vtiger CRM through 8.4.0 contains an authenticated remote code execution vulnerability in the admin module import feature that allows administrator-level attackers to upload arbitrary PHP files by submitting a crafted zip archive through the ModuleManager import function, which extracts contents directly into the modules/ directory under the web root without validating file types beyond the manifest.xml descriptor. Attackers can place executable PHP files in the modules/ directory that become directly accessible via HTTP, bypassing Vtiger's authentication and authorization layer entirely since Apache resolves the path and invokes the PHP interpreter before the application routing layer is involved, resulting in a persistent web shell independent of the originating session.
CVE-2026-55633 2026-07-08 N/A N/A
DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, a bypass of the H2 zip protocol and file dropper fix allows an authenticated attacker to upload a zip archive disguised with a .ttf extension through FontManage.saveFile and then exploit it through the zip protocol to achieve remote code execution. This issue is fixed in version 2.10.24.
CVE-2026-14489 2026-07-08 N/A 8.8 HIGH
The WHMCS Bridge plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the connect() function in all versions up to, and including, 6.9. This makes it possible for authenticated attackers, with Custom-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
CVE-2026-14158 2026-07-08 N/A 8.8 HIGH
The Widget Logic Visual plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.52 via the widget_logic_visual_check_visibility function. This is due to missing capability check and nonce verification on the widget-logic-update-conditional-tags AJAX action combined with insufficient sanitization of the 'nwlv[cod-tag]' parameter before storage and subsequent use in an eval() call. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server.
CVE-2026-48908 1 Ollyo 1 Sp Page Builder 2026-07-08 N/A 9.8 CRITICAL
A vulnerability in SP Page Builder for Joomla allows unauthenticated users to upload arbitrary files, ultimately resulting in the upload and execution of PHP code.
CVE-2026-24014 1 Apache 1 Iotdb 2026-07-07 N/A 9.8 CRITICAL
Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to build a file path without sufficient validation. If the internal DataNode RPC port is exposed to an untrusted network, an attacker may use path traversal sequences in the JAR name to write files outside the intended Trigger installation directory. This could allow arbitrary file write with the permissions of the IoTDB process. This issue affects Apache IoTDB: from 1.3.3 before 2.0.8. Users are recommended to upgrade to version 2.0.8, which fixes the issue.
CVE-2026-14775 2026-07-07 6.5 MEDIUM 6.3 MEDIUM
A vulnerability was identified in SourceCodester Onlne Examination & Learning Management System 1.0. Affected is an unknown function of the file /process_lesson.php. Such manipulation of the argument user_id leads to unrestricted upload. The attack may be launched remotely. The exploit is publicly available and might be used. The name of the affected product appears to have a typo in it.
CVE-2026-14776 2026-07-06 6.5 MEDIUM 6.3 MEDIUM
A security flaw has been discovered in SourceCodester Onlne Examination & Learning Management System 1.0. Affected by this vulnerability is the function pathinfo of the file /upload_files.php of the component Filename Extension. Performing a manipulation results in unrestricted upload. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. The name of the affected product appears to have a typo in it.
CVE-2026-14736 2026-07-06 7.5 HIGH 7.3 HIGH
A vulnerability was found in Ruijie RG-UAC up to 1.0-R1.8.2.p5. The impacted element is an unknown function of the file user_auth_commit.php. Performing a manipulation of the argument upload_image results in unrestricted upload. The attack is possible to be carried out remotely. The exploit has been made public and could be used.
CVE-2026-14698 2026-07-06 6.5 MEDIUM 6.3 MEDIUM
A security flaw has been discovered in SourceCodester Syllabus-Aligned Learning Management and Examination System 1.0. Impacted is an unknown function of the file upload_files.php.

CVE-2026-33560 1 Daktronics 6 Dmp-5000, Dmp-5000 Firmware, Dmp-8000 and 3 more 2026-07-06 N/A 7.1 HIGH
The DMP-5000 file service exposes authenticated arbitrary file upload functionality. There are exposed endpoints which allows authenticated users to upload files of any type without validation. No file extension filtering or content inspection is enforced which allows executable binaries and scripts to be accepted and written directly to the server.
CVE-2026-53909 1 Mycomplianceoffice 1 Mycomplianceoffice 2026-07-06 N/A 6.5 MEDIUM
MCO does not correctly validate types of uploaded files. File upload validation functionality relies only on client-side checks, which can be bypassed. An authorized, low-privileged attacker can upload files with arbitrary types to the server. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
CVE-2025-67289 1 Frappe 2 Erpnext, Frappe 2026-07-05 N/A 9.6 CRITICAL
