Ollama versions 0.14.0 before 0.31.2 contain an incorrect authorization vulnerability in the experimental agent mode Bash tool approval mechanism that fails to properly parse shell syntax. Attackers who can influence model output through prompt injection can execute additional shell commands by appending control operators like semicolons or logical operators to approved commands, bypassing the ses…

OpenClaw versiones 2026.5.1 a 2026.7.0 no aplican la ruta de aprobación configurada para comandos del nodo Google Meet, permitiendo que arrays de audio suministrados por atacantes se ejecuten sin validación en nodos Chrome emparejados. En despliegues con el plugin de Google Meet activo, esto expone las videollamadas empresariales y sistemas de comunicación a ejecución de código no autorizado. El impacto es alta (CVSS 8.8) en organizaciones LATAM que dependen de infraestructura de comunicaciones unificadas.

Se ha identificado un fallo en libxml2 (cuando está compilado con bindings de Python) que permite a atacantes remotos provocar una denegación de servicio mediante documentos XML especialmente diseñados con Definiciones de Tipo de Documento (DTD) que contienen valores de atributos enumerados. La vulnerabilidad explota un error de doble liberación de memoria en el manejador de retrollamada SAX attributeDecl, afectando potencialmente servidores web, APIs y aplicaciones que procesan XML en entornos LATAM.

Ollama fails to validate redirect destinations when pulling tensor-layer models, allowing unauthenticated attackers to redirect blob downloads to arbitrary hosts. An attacker can control a registry, serve a malicious tensor-layer manifest, and cause the server to issue GET requests to internal hosts including cloud metadata endpoints.

IBM Langflow OSS 1.0.0 through 1.10.3, and 1.0.0 through 1.10.3 contains a Server-Side Request Forgery (SSRF) vulnerability in the validate_model_provider_key() function for the Ollama provider. The function accepts a user-supplied OLLAMA_BASE_URL parameter and passes it directly to requests.get() without validation, scheme/host allowlisting, or filtering of private IP ranges (loopback, RFC1918, l…

Ollama (HEAD f0078ae) contains an uncontrolled memory allocation vulnerability in the GGUF metadata parser that allows remote attackers to crash the server by supplying a crafted GGUF file with attacker-controlled length and count fields in string lengths, tensor dimension counts, and metadata array counts that are used as allocation sizes without validation against remaining file size. Attackers …

Ollama downloadBlob Improper Validation of Array Index Denial-of-Service Vulnerability. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Ollama. Authentication is not required to exploit this vulnerability. The specific flaw exists within the downloadBlob function. The issue results from the lack of proper validation of user-supplied …

Unauthenticated remote information disclosure vulnerability in Ollama's model quantization engine allows an attacker to read and exfiltrate the server's heap memory, potentially leading to sensitive data exposure, further compromise, and stealthy persistence.
