CVE-2023-38290
HighSummary
Niektóre wersje oprogramowania dla urządzeń Android BLU View 2 i Sharp Rouvo V zawierają podatną aplikację wstępnie zainstalowaną o nazwie pakietu com.evenwell.fqc, która umożliwia lokalnym aplikacjom stron trzecich wykonywanie dowolnych poleceń powłoki w jej kontekście z powodu niewystarczającej kontroli dostępu. Wykorzystanie tej podatności nie wymaga specjalnych uprawnień ani interakcji użytkownika poza zainstalowaniem i uruchomieniem aplikacji zewnętrznej.
Risk Assessment
Podatność ta pozwala lokalnym aplikacjom na dostęp do wrażliwej funkcjonalności, która jest zazwyczaj zarezerwowana dla aplikacji wstępnie zainstalowanych, co może prowadzić do uzyskania danych użytkownika oraz poważnych naruszeń bezpieczeństwa urządzenia.
Recommendation
Zaleca się usunięcie lub zaktualizowanie podatnej aplikacji com.evenwell.fqc oraz monitorowanie urządzeń w celu wykrycia i usunięcia potencjalnie złośliwych aplikacji stron trzecich.

An OS command injection vulnerability was found in AhsayCBS up to version 10.3.2 in the file /rps/api/json/UpdateReceivers.do. The attack can be launched remotely, and the exploit has been published. Upgrading to version 10.3.4 resolves the issue.
- CVE-2026-105105Critical
Missing authentication for critical function in the ait-server telemetry and command broker in NASA-AMMOS AIT-Core through 3.1.1. An unauthenticated remote attacker with network access to the ZeroMQ message bus can inject spacecraft command data, exfiltrate command and telemetry traffic, inject forged telemetry, or disrupt the bus. The ZeroMQ broker binds XSUB and XPUB sockets to all interfaces by default without authentication.
- CVE-2026-71885Critical
In Bouncy Castle for Java before 1.86, the Messaging Layer Security (MLS, RFC 9420) implementation did not bind an X.509 credential to a LeafNode's signature_key. LeafNode.verify() checked a leaf's signature against the signature_key carried in the leaf itself, while the credential's X.509 certificate chain was stored but never parsed or validated, so the end-entity certificate's public key was never required to match signature_key as RFC 9420 sec. 5.3 requires. An attacker could present another party's certificate as its credential while signing the leaf, and the enclosing KeyPackage, with an unrelated key, and be accepted under that other party's identity through KeyPackage.verify() and the Group leaf-validation path.
- CVE-2026-92084Critical
The Beaver Builder Page Builder plugin for WordPress up to version 2.11.0.5 is vulnerable to arbitrary shortcode execution. This is due to insufficient validation before running do_shortcode, allowing unauthenticated attackers to execute arbitrary shortcodes. Exploitation requires a page with the Sidebar module containing a widget that displays attacker-controlled text, such as the Recent Comments widget with approved comments.
- CVE-2026-87115Critical
The VikAppointments Services Booking Calendar plugin for WordPress up to version 1.2.21 is vulnerable to arbitrary file deletion due to insufficient file path validation in the extract function. This allows unauthenticated attackers to delete arbitrary files on the server, potentially leading to remote code execution (e.g., by deleting wp-config.php). Exploitation requires at least one File-type custom field published on the confirmation page.
- CVE-2026-105080Critical
In ConvertX before 0.19.0, converters/calibre.ts does not block recipe files and passes them to the ebook-convert program from Calibre. This allows executable code in .recipe or .downloaded_recipe files.
- CVE-2026-84411Critical
The web management service in affected RouterOS versions contains an integer underflow in HTTP request body handling that is reachable before authentication. An unauthenticated network attacker can exploit a single crafted request to achieve remote code execution as root or cause a denial of service.
- CVE-2026-95102Critical
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to impersonate charging stations. By exploiting this weakness, attackers can gain unauthorized access to sensitive data or perform unauthorized actions. Since no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.
Original NVD description (English source)
Certain software builds for the BLU View 2 and Sharp Rouvo V Android devices contain a vulnerable pre-installed app with a package name of com.evenwell.fqc (versionCode='9020801', versionName='9.0208.01' ; versionCode='9020913', versionName='9.0209.13' ; versionCode='9021203', versionName='9.0212.03') that allows local third-party apps to execute arbitrary shell commands in its context (system user) due to inadequate access control. No permissions or special privileges are necessary to exploit the vulnerability in the com.evenwell.fqc app. No user interaction is required beyond installing and running a third-party app. The vulnerability allows local apps to access sensitive functionality that is generally restricted to pre-installed apps, such as programmatically performing the following actions: granting arbitrary permissions (which can be used to obtain sensitive user data), installing arbitrary apps, video recording the screen, wiping the device (removing the user's apps and data),
