Technical Analysis
In Spring AI's Semantic Cache support, the context hash used to isolate cached responses between different system prompts is flawed. This flaw can cause cached responses to be shared across unrelated contexts, leading to exposure of cached data to incorrect or unintended contexts. The affected version is Spring AI 2.0.0. The CVSS 3.1 vector is AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N, reflecting network attack vector, high attack complexity, low privileges required, no user interaction, unchanged scope, and low confidentiality and integrity impacts with no availability impact.
Potential Impact
The vulnerability may result in limited exposure of cached responses to unrelated contexts, potentially leaking information between different system prompts. The impact is limited to confidentiality and integrity with no effect on availability. There are no known exploits in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is provided in the available data.
