CVE-2025-69256
HighSummary
W frameworku Serverless, od wersji 4.29.0 do 4.29.3, występuje podatność na wstrzykiwanie poleceń w pakiecie serwera MCP (@serverless/mcp). Dotyczy ona jedynie użytkowników eksperymentalnej funkcji serwera MCP, co stanowi mniej niż 0,1% użytkowników frameworka Serverless.
Risk Assessment
Wykorzystanie tej podatności może prowadzić do zdalnego wykonania kodu z uprawnieniami procesu serwera, co stwarza poważne zagrożenie dla bezpieczeństwa aplikacji i danych organizacji.
Recommendation
Zaleca się aktualizację frameworka Serverless do wersji 4.29.3 lub nowszej, aby usunąć tę podatność. Użytkownicy funkcji MCP powinni również rozważyć wyłączenie tej funkcji, jeśli to możliwe.

An unauthenticated Remote Code Execution vulnerability was found in REDCap 13.3.0 and higher in the survey passthrough routing and Data Import processing logic. An attacker can manipulate HTTP requests to access an unintended controller route from a public survey context and supply a crafted file-path/stream parameter during import handling. Exploitation requires knowledge of a valid public survey hash.

Use-after-free vulnerability in Suricata before 8.0.7 occurs in the Http2ThreadMultiBuf mechanism when a transaction is inspected by rules using http.response_header with and without a transform.
- CVE-2026-94083Critical
In Suricata before 8.0.7, a type confusion in DoH2 can cause an invalid free because cleanup code for HTTP2 state runs even though the actual state is HTTP1 (when there is a DoH2 request with an HTTP1 to HTTP2 upgrade). This requires app-layer.protocols.doh2 to be enabled, which is default in 8.x versions.

A vulnerability has been identified in the Totolink A3002MU router (version Hh-B20211125.1046) in the formWsc function of the /boafrm/formWsc file. Manipulation of the localPin argument leads to command injection. The attack can be launched remotely, and a public exploit is already available.
- CVE-2026-86591Critical
The Botiga Pro WordPress plugin before 1.6.5 does not perform any authorisation checks on one of its REST routes, allowing unauthenticated users to update arbitrary WordPress options with arbitrary values, which could lead to privilege escalation and a full site takeover. The same route also allows unauthenticated users to store arbitrary web scripts which are then executed on every page of the site's front end, as well as to move arbitrary posts to the trash.

A vulnerability has been discovered in the Totolink A3002MU router (version Hh-B20211125.1046) in the formWlWds function of the /boafrm/formWlWds file. Manipulation of the submit-url argument results in a buffer overflow. The attack can be launched remotely, and a public exploit has already been released.
Original NVD description (English source)
The Serverless Framework is a framework for using AWS Lambda and other managed cloud services to build applications. Starting in version 4.29.0 and prior to version 4.29.3, a command injection vulnerability exists in the Serverless Framework's built-in MCP server package (@serverless/mcp). This vulnerability only affects users of the experimental MCP server feature (serverless mcp), which represents less than 0.1% of Serverless Framework users. The core Serverless Framework CLI and deployment functionality are not affected. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.exec`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.).
