Summary
A container privilege escalation flaw was found in certain Container-native Virtualization images. The /etc/passwd file is created with group-writable permissions during build time, allowing an attacker with non-root access to modify it and add a user with arbitrary UID, including 0, leading to full root privileges within the container.
Risk Assessment
Risk of full container compromise by an unprivileged user, potentially enabling further attacks on the infrastructure.
Recommendation
Rebuild images with correct permissions for /etc/passwd and restrict access to containers.

An authenticated high privilege user can inject arguments in troubleshooting commands resulting in privilege escalation.

SQL injection in the NetBoard CRM demo platform; specifically, the vulnerable component is the 'user-name' POST parameter in the '/module/auth/recovery.php' endpoint. The parameter is vulnerable to blind attacks based on Boolean, error, time-based and UNION techniques. Exploitation allows attackers to extract confidential information (such as the version and type of backend used), alter data or further compromise the CRM environment.

OS Command Injection in the login.xgi CGI endpoint in Iskratel Innbox GPON ONT devices allows an unauthenticated remote attacker to execute arbitrary commands as root via the CLI parameter.
- CVE-2026-85097Critical
The Bricksforge plugin for WordPress is vulnerable to unauthenticated arbitrary file upload in versions up to, and including, 3.1.8.9. This is due to insufficient validation of the attacker-controlled URL field in the 'temporaryFileUploads' parameter during form submission. An unauthenticated attacker can first obtain a valid nonce via the bricksforge_regenerate_nonce AJAX endpoint, then upload a GIF/PHP polyglot file to the temporary upload directory where MIME type validation is correctly performed. Subsequently, the attacker can submit a form with a crafted 'temporaryFileUploads' parameter where the server-side file path points to the validated GIF file, but the attacker-controlled url field ends with a .php extension. This makes it possible for unauthenticated attackers to upload and execute arbitrary PHP code on the server.

The SecuShare Pro developed by Openfind has an OS Command Injection vulnerability. Unauthenticated remote attackers can inject arbitrary OS commands and execute them on the server.
- CVE-2026-103692Critical
The Frontend Dashboard WordPress plugin before 3.0.5 does not perform any authorisation or nonce check on actions available to unauthenticated users that call an attacker-chosen PHP function or class method with the request data, allowing unauthenticated users to take over any account, including administrators.
- CVE-2026-103646Critical
The Ultimate Multisite WordPress plugin before 2.17.0 does not require authentication before a logged-out checkout is linked to, and logged in as, an existing WordPress account matching the submitted email address, and its duplicate-account check normalizes that address differently from the lookup used to create the customer, so an unauthenticated attacker can log in as any existing user, including a Network Super Admin, whose email address they know. This bypass is not addressed by the 2.15.1 fix for CVE-2026-75957 and remains exploitable in all versions up to and including 2.16.1, the releases that fix was expected to cover. Exploitation requires a checkout form configured without a password field (auto-generated password) and a target account that has no existing customer record in the Ultimate Multisite WordPress plugin before 2.17.0.
- CVE-2026-17609Critical
The Super Forms plugin for WordPress up to version 6.3.316 contains an arbitrary directory deletion vulnerability. This is due to insufficient validation of attacker-controlled JSON fields and an ineffective ABSPATH guard that can be easily bypassed. An unauthenticated attacker can recursively delete arbitrary directories on the server, including the WordPress root directory, provided the administrator has enabled the 'Delete files from server after form submissions' setting.
- CVE-2026-107282Critical
Vulnerability in AsyncHttpClient (AHC) library before versions 3.0.13 and 2.16.1 allows cross-host request replay that updates the current request but leaves the target request and proxy context pointing to the original origin. This can send the original host's path, Host header, Authorization credentials, or plaintext request to the replay destination.
- CVE-2026-76268Critical
Vulnerability in Splunk Enterprise before versions 10.4.3 and 10.2.7 allows an unauthenticated user with network access to the Patroni REST API on a search head cluster member to execute attacker-controlled OS commands. The interface does not require authentication for critical configuration operations.
Original NVD description (English source)
A container privilege escalation flaw was found in certain Container-native Virtualization images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.
