CVE-2026-40979 Details
Description
In Spring AI, having access to a shared environment can expose the ONNX model used by the application. Affected versions: Spring AI: 1.0.0 - 1.0.5 (fixed in 1.0.6), 1.1.0 - 1.1.4 (fixed in 1.1.5)
A vulnerability in Spring AI versions 1.0.0 through 1.0.5 and 1.1.0 through 1.1.4 allows exposure of the ONNX model used by the application. This issue arises when applications utilize the 'TransformersEmbeddingModel' with caching enabled, defaulting to a world-writable and predictable temporary directory. Access to a shared environment can further exacerbate the problem.
Users should upgrade to Spring AI version 1.0.6 or 1.1.5, depending on their current version. No additional mitigation steps are necessary.
