CVE-2026-8677
MediumCVSS 6.4Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
The Prime Elementor Addons plugin for WordPress (versions up to and including 1.3.3) is vulnerable to Stored Cross-Site Scripting via Widget HTML Tag Settings due to insufficient input sanitization and output escaping. Authenticated attackers with contributor-level access or above can inject arbitrary scripts that execute whenever a user accesses an injected page. The exploit works even without the unfiltered_html capability because the payload (e.g., 'img src=x onerror=alert(document.domain)') contains no angle brackets and passes through Elementor's wp_kses_post() filter unchanged.
Risk Assessment
The risk is the injection of malicious scripts that can steal session data, redirect users, or perform other unauthorized actions in the victim's browser context.
Recommendation
Update the Prime Elementor Addons plugin to version 1.3.4 or later if available, or apply temporary mitigations such as restricting access to widget editing.

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.
- CVE-2026-109566Critical
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 Prime Elementor Addons – Lightweight Elementor Widgets for Faster Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Widget HTML Tag Settings in all versions up to, and including, 1.3.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit succeeds even for users without the unfiltered_html capability because the payload (e.g., 'img src=x onerror=alert(document.domain)') contains no HTML angle brackets and therefore passes through Elementor's wp_kses_post() filter unchanged at save time.
