No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Ollama是Ollama公司开源的一个可以在本地设备上运行、管理和自定义大语言模型的工具。 Ollama 0.30.0版本至0.33.2版本存在服务端请求伪造漏洞，该漏洞源于在拉取tensor-layer模型时未能验证重定向目标，可能导致未经身份验证的攻击者控制registry并服务恶意tensor-layer manifest，将blob下载重定向到任意主机，进而使服务器向包括云元数据端点在内的内部主机发起GET请求，造成信息泄露。

Vulnerability Title
Ollama 0.30.0 through 0.33.2 SSRF via Cross-Host Tensor Blob Redirect
Source: CVE Program / CVE List V5
Vulnerability Description
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.
