Wallos, an open-source self-hostable subscription tracker, contains a Server-Side Request Forgery (SSRF) vulnerability in versions prior to 4.7.0 that allows authenticated users to access internal network services, cloud metadata endpoints, and localhost-bound services. The vulnerability exists in three unprotected attack surfaces: the AI Ollama host parameter, the AI recommendations endpoint, and the notification cron job-areas that were missed when SSRF protections were partially implemented in an earlier patch (CVE-2026-30840). An attacker with valid credentials can leverage these endpoints to reach sensitive internal resources including AWS IMDSv1, GCP, and Azure metadata services.
Ollama MCP Server has a command injection vulnerability in execAsync (EPSS 1.0%) allowing remote attackers to execute arbitrary commands on systems running the Ollama AI integration.
An issue in ollama v.0.12.10 allows a remote attacker to cause a denial of service via the fs/ggml/gguf.go, function readGGUFV1String reads a string length from untrusted GGUF metadata [CVSS 7.5 HIGH]
An issue in ollama v.0.12.10 allows a remote attacker to cause a denial of service via the GGUF decoder [CVSS 7.5 HIGH]
Ollama 0.11.5-rc0 through current version 0.13.5 contain a null pointer dereference vulnerability in the multi-modal model image processing functionality. [CVSS 7.5 HIGH]
An issue in Ollama v0.1.33 allows attackers to delete arbitrary files via sending a crafted packet to the endpoint /api/pull. Rated medium severity (CVSS 6.6), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
A vulnerability in the Ollama server version 0.5.11 allows a malicious user to cause a Denial of Service (DoS) attack by customizing the manifest content and spoofing a service.
