mcp-shell is an MCP server for running shell commands securely, auditably, and on demand. Prior to 0.6.0, the default Docker security.yaml includes /bin/bash in allowed_executables, while security.go validates only the first token and checkBlockedPatternsAndCommands does not reject the shell command-mode flag -c. A caller of the shell_exec MCP tool can provide the command argument `/bin/bash -c

mcp-shell is an MCP server for running shell commands securely, auditably, and on demand. Prior to 0.6.0, the default security.yaml allows /usr/bin/git, while security.go omits ! from containsShellMetacharacters and containsDangerousShellConstructs and applies no per-executable argument policy. A caller of the shell_exec MCP tool can provide the command argument /usr/bin/git -c alias.pwn=!

Nokogiri versions before 1.13.5 contain an integer overflow vulnerability in packaged libxml2 buffer handling functions that allows attackers to cause out-of-bounds memory writes. Attackers can exploit this by crafting multi-gigabyte XML files to trigger buffer overflows resulting in information disclosure, data modification, or denial of service.

An authenticated user may initiate repository migration operations without required repository permissions, potentially causing information disclosure, unauthorized state changes, and service disruption. Fixed versions address the issue.

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, spider_tools._host_is_blocked() does not resolve ordinary hostnames before scrape_page fetches them. A hostname such as 127.0.0.1.nip.io passes validation and resolves to loopback, permitting internal HTTP access. The fix uses socket.getaddrinfo and fails closed on DNS errors. This issue is fixed in version 1.6.58.

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the FileMemory constructor joins unsanitized user_id into self.user_path. A caller supplying ../ or path separators can escape the memory directory and write JSON data to arbitrary process-writable locations. The fix sanitizes user_id before constructing self.user_path. This issue is fixed in version 1.6.58.

A weakness has been identified in dekdee adobe-xd-mcp 1.0.0. Impacted is an unknown function of the file src/parsers/xd-parser.ts of the component file-access-from-request Endpoint. Executing a manipulation of the argument outputFile/outputDir can lead to path traversal. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. T…

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the web_crawl function validates only the initial URL before _crawl_with_httpx uses httpx.Client(follow_redirects=True). Redirect targets are not revalidated, so an attacker who influences a crawl target can redirect a public URL to loopback, private network, or cloud metadata services while ALLOW_LOCAL_CRAWL remains disable…

Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based on querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and cleanse more bytes than that query reports, causing an 8-byte out-of-bounds heap write. Impact summary: An attacker who supplies a crafted CMS message can trigger a deterministic 8-byte out-of-bounds heap write when the victim decry…

Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC handshake can cause connection-scoped memory growth which may lead to Denial of Service through memory exh…

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large amount of memory, which may lead to a Denial of Service. CWE: CWE-405: Asymmetric Resource Consumptio…

Crater Invoice through 6.0.6 contains a path traversal vulnerability in the self-update API that allows authenticated company owners to write arbitrary files outside the intended extraction directory by supplying crafted ZIP archives with ../ sequences to the unzip endpoint. Attackers can exploit unsanitized ZIP entry names passed to PHP's ZipArchive::extractTo() to write arbitrary PHP files into …

Issue summary: In a server or client configuration with RFC7250 Raw Public Keys (RPKs) enabled, and only the private key (with no associated certificate) configured locally, a NULL pointer dereference may occur when the remote peer solicits raw public keys and also sends the typically omitted "signature_algorithms_cert" TLS extension. Impact summary: The impact is limited to a possible Denial of …

Issue summary: QUIC server may double free QRX (QUIC record layer RX) object when channel creation fails for initial packet. Impact summary: Double free leads to heap corruption, which typically results in termination of QUIC server process, leading to Denial of Service. There is so far no evidence that this double free is exploitable for remote code execution, thus it is considered highly impro…

Ech0 antes de la versión 4.7.3 presenta un fallo grave en la revocación de tokens de acceso configurados con opción de no expiración, permitiendo a atacantes mantener acceso autenticado permanente tras robo de credenciales. Tres mecanismos de revocación fallan simultáneamente: logout genera pánico en campo ExpiresAt nulo, RevokeToken se omite cuando remainTTL es cero, y eliminación administrativa no registra en lista negra el JTI, dejando tokens JWT robados válidos criptográficamente. Afecta sistemas de autenticación en infraestructuras altas de empresas mexicanas y latinoamericanas.

Ech0 versiones anteriores a 4.5.1 presentan una falla de autorización donde los tokens de sesión no validan permisos en el middleware RequireScopes, permitiendo que usuarios autenticados sin privilegios de administrador accedan a endpoints protegidos. Los atacantes pueden extraer registros del sistema, estadísticas de visitantes, correos de usuarios y suscribirse a logs en vivo mediante WebSocket utilizando tokens de sesión válidos.

Ech0 versiones 4.3.4 y anteriores no validan correctamente los scopes de tokens de acceso en rutas administrativas privilegiadas (/api/inbox, /api/panel/comments, /api/backup/export), permitiendo a atacantes con tokens limitados ejecutar operaciones administrativas. El gestor de exportación de respaldos descarta completamente la validación de metadatos, exponiendo datos sensibles de usuarios y configuraciones altas en infraestructuras de LATAM.

Ech0 versiones hasta 4.5.6 presenta una vulnerabilidad en la validación de redirect_uri OAuth que solo verifica esquema y host, ignorando ruta, parámetros y fragmentos. Esto permite a atacantes redirigir tokens de autenticación a dominios controlados después de pasar la validación inicial. Empresas en LATAM que usan Ech0 para autenticación federada enfrentan riesgo alta de compromiso de sesiones y acceso no autorizado a sistemas integrados.

Ech0 versiones anteriores a 5.0.1 no valida el tamaño ni estructura del encabezado Accept-Language, permitiendo que solicitudes malformadas causen agotamiento de recursos en el middleware i18n. La vulnerabilidad explota una bypass parcial de CVE-2022-32149 en la librería golang.org/x/text, afectando aplicaciones Go que procesan solicitudes HTTP desde internet público o redes no confiables.

El plugin ShopEngine Elementor WooCommerce Builder para WordPress (versiones hasta 4.9.4) contiene una vulnerabilidad de escalada de privilegios (CVSS 7.2) en la función rum_importer() que permite a atacantes ejecutar acciones administrativas sin validación de permisos. Afecta a tiendas en línea en México y LATAM que utilicen este componente para gestionar productos y opciones de WooCommerce. Un atacante puede modificar configuraciones altas, crear cuentas administrativas o inyectar código malicioso en la base de datos.
