CVE-2026-27626
CriticalSummary
OliveTin umożliwia dostęp do predefiniowanych poleceń powłoki z interfejsu webowego. W wersjach do 3000.10.0, kontrola bezpieczeństwa argumentów powłoki (`checkShellArgumentSafety`) blokuje kilka niebezpiecznych typów argumentów, ale nie `password`, co pozwala na wstrzykiwanie metacharakterów powłoki i wykonywanie dowolnych poleceń systemowych.
Risk Assessment
Organizacja jest narażona na zdalne wykonanie kodu (RCE) przez uwierzytelnionych użytkowników oraz nieautoryzowanych atakujących, co może prowadzić do poważnych naruszeń bezpieczeństwa i utraty danych.
Recommendation
Zaleca się aktualizację OliveTin do najnowszej wersji, aby usunąć tę podatność oraz wprowadzenie dodatkowych środków zabezpieczających, takich jak ograniczenie dostępu do webhooków z zewnętrznych źródeł.

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)
OliveTin gives access to predefined shell commands from a web interface. In versions up to and including 3000.10.0, OliveTin's shell mode safety check (`checkShellArgumentSafety`) blocks several dangerous argument types but not `password`. A user supplying a `password`-typed argument can inject shell metacharacters that execute arbitrary OS commands. A second independent vector allows unauthenticated RCE via webhook-extracted JSON values that skip type safety checks entirely before reaching `sh -c`. When exploiting vector 1, any authenticated user (registration enabled by default, `authType: none` by default) can execute arbitrary OS commands on the OliveTin host with the permissions of the OliveTin process. When exploiting vector 2, an unauthenticated attacker can achieve the same if the instance receives webhooks from external sources, which is a primary OliveTin use case. When an attacker exploits both vectors, this results in unauthenticated RCE on any OliveTin instance using Shell
