CVE-2011-4879
HighSummary
miniweb.exe w serwerze WWW HMI w Siemens WinCC flexible 2004, 2005, 2007 i 2008 przed SP3 oraz WinCC V11 przed SP2 Update 1 nieprawidłowo obsługuje URI zaczynające się od znaku 0xfa. To pozwala zdalnym atakującym na odczyt danych z dowolnych lokalizacji pamięci lub spowodowanie awarii aplikacji poprzez spreparowane żądanie POST.
Risk Assessment
Podatność ta może prowadzić do nieautoryzowanego dostępu do wrażliwych danych lub do awarii systemu, co może zakłócić działanie krytycznych aplikacji w organizacji.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszej wersji, która zawiera poprawki bezpieczeństwa, oraz monitorowanie ruchu sieciowego w celu wykrywania potencjalnych prób ataków.

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress in all versions up to and including 1.2.3 is vulnerable to authorization bypass. This is due to the plugin not properly verifying that a user is authorized to perform an action. This allows unauthenticated attackers to modify the email address of arbitrary user accounts, including administrators, which can be leveraged to reset the account password and gain access.
- CVE-2026-12793Critical
The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress in all versions up to and including 3.6.2 is vulnerable to Privilege Escalation. This is due to the plugin not validating that a submitted form ID belongs to a JetFormBuilder form before parsing the referenced post's content as form schema and executing an Advanced Validation server-side callback. This allows unauthenticated attackers to create a new administrator-level user account.

- CVE-2026-73437Critical
On affected platforms running Arista EOS with Dynamic Host Configuration Protocol (DHCP) relay configured, an unauthenticated attacker with network access could send a crafted DHCP reply packet from an IP address that is not configured as a helper address, and the relay agent would forward it to clients without validating the source.
- CVE-2026-61560Critical
`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Prior to version 2.1.27, the SSE transport mode (`SSE=true`) exposes all MCP tools without any authentication. The `upload_markdown` tool reads arbitrary files from the server's local filesystem via an unsanitized `file_path` parameter and uploads them to a GitLab project.
Original NVD description (English source)
miniweb.exe in the HMI web server in Siemens WinCC flexible 2004, 2005, 2007, and 2008 before SP3; WinCC V11 (aka TIA portal) before SP2 Update 1; the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime does not properly handle URIs beginning with a 0xfa character, which allows remote attackers to read data from arbitrary memory locations or cause a denial of service (application crash) via a crafted POST request.
