CVE-2025-67112
CriticalSummary
Wykorzystanie twardo zakodowanego klucza AES-256-CBC w implementacji tworzenia kopii zapasowych/przywracania konfiguracji w oprogramowaniu układowym Small Cell Sercomm SCE4255W (FreedomFi Englewood) przed wersją DG3934v3@2308041842 umożliwia zdalnym uwierzytelnionym użytkownikom odszyfrowanie, modyfikację i ponowne zaszyfrowanie konfiguracji urządzenia.
Risk Assessment
To pozwala na manipulację poświadczeniami oraz eskalację uprawnień za pomocą funkcji importu/eksportu w interfejsie graficznym, co stanowi poważne zagrożenie dla bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację oprogramowania układowego do najnowszej wersji, aby usunąć twardo zakodowany klucz oraz wprowadzenie dodatkowych środków zabezpieczających dla funkcji importu/eksportu.

The Avada (Fusion) Builder plugin for WordPress up to version 7.16.1 contains an authorization bypass vulnerability. An unauthenticated attacker can invoke arbitrary WordPress action hooks by sending a crafted request to the public form-submit endpoint, potentially leading to permanent deletion of content (posts, pages, comments) or other state changes.
- CVE-2026-103889Critical
The 3D Product configurator plugin for WooCommerce up to version 2.16.2 is vulnerable to Remote Code Execution via the 'xpv_image' parameter. Missing authentication and nonce checks on the wp_loaded handler, combined with lack of sanitization before echoing into a Dompdf-rendered HTML template with PHP execution enabled, allow unauthenticated attackers to execute code on the server.
- CVE-2026-94589Critical
The Extensions For CF7 plugin up to version 3.4.5 is vulnerable to Arbitrary File Upload via the extcf7_submit function. Missing file extension, MIME type, and size validation, combined with absence of PHP-execution guards and a sanitize_file_name() bypass, allow unauthenticated attackers to upload executable files, leading to remote code execution.
- CVE-2026-107645Critical
The Blocksy Companion plugin up to version 2.1.58 is vulnerable to privilege escalation. The implement_user_registration() AJAX handler disables Dokan's vendor-registration nonce check and trusts an attacker-supplied $_POST['role'] value, allowing unauthenticated attackers to obtain a Dokan 'seller' account and be auto-authenticated, even when vendor signup is disabled.
- CVE-2026-104732Critical
The Advanced IP Blocker plugin up to version 8.13.13 is vulnerable to Authentication Bypass. The handle_login_action() function performs no server-side check that step-1 password authentication was completed, and an error branch unconditionally mints a fresh nonce for any unauthenticated caller. This allows attackers to brute-force an unthrottled 6-digit TOTP code and obtain a fully authenticated session for any 2FA-enabled account, including administrators.

In JetBrains Exposed before version 1.5.1, SQL injection was possible via unescaped string arguments of several SQL functions.
- CVE-2026-108269Critical
In versions prior to 0.5.0 of Remote Attestation TLS Clients for Rust and Go, RA-TLS challenge verifiers accepted quotes bound to the certificate public key and client nonce but not to the active TLS session. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing clients to accept an attacker-terminated connection as the attested enclave. This issue is fixed in 0.5.0.
- CVE-2026-108268Critical
In versions prior to tdx-v0.2.43 and tdx-gpu-v0.6.27, Enclave OS Virtual placed the certificate public-key hash and client nonce in quote ReportData but omitted a value bound to the active TLS session. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing a relying party to accept an attacker-terminated connection as the attested enclave. This issue is fixed in tdx-v0.2.43 and tdx-gpu-v0.6.27.
- CVE-2026-108267Critical
In versions prior to privasys-v0.5.1-go1.26.5, Privasys Go (a fork of Go with RA-TLS support) in challenge mode bound quote ReportData to the certificate public key and client nonce but not to the active TLS session. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing a relying party to accept a handshake terminated by the attacker as an attested enclave connection. This issue is fixed in privasys-v0.5.1-go1.26.5.
- CVE-2026-108266Critical
In versions prior to privasys-v0.8.1, Privasys rustls (a fork of the rustls TLS library with RA-TLS support) emitted RA-TLS challenge certificates whose quote ReportData was bound to the certificate public key and client nonce but not to the active TLS session. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing a relying party to accept an attacker-terminated connection as the attested enclave. This issue is fixed in privasys-v0.8.1.
Original NVD description (English source)
Use of a hard-coded AES-256-CBC key in the configuration backup/restore implementation of Small Cell Sercomm SCE4255W (FreedomFi Englewood) firmware before DG3934v3@2308041842 allows remote authenticated users to decrypt, modify, and re-encrypt device configurations, enabling credential manipulation and privilege escalation via the GUI import/export functions.
