Low risk9th percentile - higher than 9% of all known CVEs
Summary
The Open User Map PRO plugin for WordPress up to version 1.4.31 is vulnerable to Stored Cross-Site Scripting via the 'oum_location_notification' parameter due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts that execute whenever a user accesses an injected page.
Risk Assessment
An attacker can inject a malicious script that executes in the browser of every visitor, potentially stealing session data, redirecting users, or performing other harmful actions.
Recommendation
Upgrade the Open User Map PRO plugin to a version later than 1.4.31.

Qexo versions 4.0.0 through 4.2.0 expose /api/init_step/ without authentication, authorization, or a setup-completion guard. An unauthenticated requester with a valid CSRF token can reset the INIT setting and re-enter the setup flow, potentially exposing stored PROVIDER configuration including credentials.

Rapyd Admin versions 9.0.0 before 9.20.0 contain hard-coded credentials that allow remote unauthenticated attackers to gain super-admin access through an admin@laravel account with password admin. The account is seeded by the installer and silently re-created on every rpd:make run, bypassing authorization and tenant scoping.

Netcore NR268 version 1.7.121109 contains an argument injection vulnerability in the execvp function of the file /router/DDNSset.cgi in the DDNS component. Manipulating the Hostname argument can lead to argument injection, and the attack can be launched remotely.
- CVE-2025-71429Critical
GPT-SoVITS through 20250606v2pro contains an OS command injection vulnerability in tools/uvr5/vr.py that allows unauthenticated attackers to execute commands via output folder paths. Attackers can enter shell substitutions like $(...) in the UVR5 WebUI output folder textboxes with mp3 or m4a export to run commands as the server user.
- CVE-2026-96012Critical
IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 are vulnerable to privilege escalation. An authenticated attacker could craft a malicious request that bypasses additional authorization and input validation checks to execute malicious code and gain elevated privileges.
- CVE-2026-109575Critical
HAProxy Data Plane API versions 2.2.0 through 3.4.3 (and corresponding Enterprise Edition releases) have process-global authentication logic that improperly drops security controls across multiple transport types. When a TLS CA is configured and a numeric TLS port is specified, the application globally disables Basic authentication on its shared internal request handler, allowing unauthenticated attackers to reach affected HTTP or UNIX endpoints and completely bypass credentials to gain full API administrative access.
Original NVD description (English source)
The Open User Map PRO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'oum_location_notification' parameter in versions up to, and including, 1.4.31 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
