CVE-2024-50338
HighSummary
Git Credential Manager (GCM) to bezpieczny pomocnik do zarządzania poświadczeniami Git, działający na systemach Windows, macOS i Linux. Protokół poświadczeń Git jest oparty na tekście i składa się z par klucz-wartość, jednak dokumentacja Git ogranicza użycie znaku NUL oraz nowych linii w kluczach lub wartościach.
Risk Assessment
Nieprawidłowe przetwarzanie nowych linii może prowadzić do błędów w walidacji poświadczeń, co stwarza ryzyko nieautoryzowanego dostępu do repozytoriów Git. Organizacje powinny być świadome potencjalnych luk w zabezpieczeniach związanych z obsługą poświadczeń.
Recommendation
Zaleca się aktualizację Git Credential Manager do najnowszej wersji oraz monitorowanie i audytowanie użycia poświadczeń w celu zminimalizowania ryzyka nieautoryzowanego dostępu.

A use of hard-coded cryptographic key vulnerability in Johnson Controls EasyIO FS32 allows retrieval of embedded sensitive data. This issue affects EasyIO FS32 versions before 3.0b63.
- CVE-2026-18397Critical
This vulnerability enables unauthenticated remote code execution (RCE) on a victim's machine by exploiting a combination of cryptographic weaknesses and memory management issues in the SConnect native host component. The attack leverages an unrestricted messaging interface between an attacker-controlled web page and the native host, allowing malicious input to bypass security checks.

Teledyne FLIR Aware2 versions through 6.9.0.2 (PackBot) and 1.7.9 (FirstLook) contain hardcoded passwords in access control. Remote unauthenticated attackers can read them from firmware or documentation and access/reconfigure the robots.
- CVE-2026-55393Critical
Teledyne FLIR Aware2 versions through 6.9.0.2 (PackBot) and 1.7.9 (FirstLook) have unvalidated pathnames in the web interface. Remote unauthenticated attackers can use path traversal to read configuration and security parameters.
- CVE-2026-56662Critical
In GetSimple CMS CE prior to version 1.5, the UpdateCE update form lacked an anti-CSRF token and the POST handler did not verify token or request origin. A remote attacker can host a page that auto-submits a forged POST; when an authenticated admin visits it, the server performs an attacker-directed download-and-deploy operation, leading to remote code execution. The url field is also written unescaped, allowing HTML injection.
- CVE-2026-56660Critical
In GetSimple CMS CE prior to version 1.5, the update handler in UpdateCE.php downloads a ZIP archive and extracts it into the web root without validating file types or extraction paths. Because PHP files are written into a web-accessible directory, an attacker who can cause a malicious archive to be processed achieves remote code execution as the web-server user. Entry names are also used unsafely, allowing directory traversal (../) to write files outside the intended directory.
- CVE-2026-14984Critical
Teledyne FLIR Aware2 versions through 6.9.0.2 transmit data in cleartext in primary control endpoints. Remote unauthenticated attackers can intercept, hijack, or modify session traffic against PackBot robots via sniffing or hijacking network traffic.

A path traversal vulnerability in Fortinet FortiMail (versions 8.0.0-8.0.1, 7.6.0-7.6.6, 7.4.0-7.4.8, 7.2.0-7.2.9) stems from improper limitation of a pathname to a restricted directory. An unauthenticated attacker can write arbitrary files on the underlying system via crafted HTTP or HTTPS requests.
- CVE-2026-102628Critical
The Cadmos LTI application hosted at cadmos.eummena.io had Laravel debug mode enabled (APP_DEBUG=true, APP_ENV=local) in a publicly accessible environment. An unauthenticated attacker could send a GET request and trigger an unhandled exception, causing Laravel to expose the entire server environment, including all .env configuration variables, in plaintext. Fixed on or before 2026-09-02.

DHIS2 versions from 2.42.0 to before 2.42.5.1, and from 2.43.0 to before 2.43.0.1, are vulnerable to remote code execution (RCE) via unsafe Java deserialization. This issue has been patched in versions 2.42.5.1, 2.43.0.1, and 2.44.
Original NVD description (English source)
Git Credential Manager (GCM) is a secure Git credential helper built on .NET that runs on Windows, macOS, and Linux. The Git credential protocol is text-based over standard input/output, and consists of a series of lines of key-value pairs in the format `key=value`. Git's documentation restricts the use of the NUL (`\0`) character and newlines to form part of the keys or values. When Git reads from standard input, it considers both LF and CRLF as newline characters for the credential protocol by virtue of calling `strbuf_getline` that calls to `strbuf_getdelim_strip_crlf`. Git also validates that a newline is not present in the value by checking for the presence of the line-feed character (LF, `\n`), and errors if this is the case. This captures both LF and CRLF-type newlines. Git Credential Manager uses the .NET standard library `StreamReader` class to read the standard input stream line-by-line and parse the `key=value` credential protocol format. The implementation of the `ReadLineA
