CVE-2026-5594 Details
Description
A weakness has been identified in premAI-io premsql up to 0.2.1. Affected is the function eval of the file premsql/agents/baseline/workers/followup.py. This manipulation of the argument result causes code injection. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A remote code execution vulnerability has been identified in the premAI-io premsql library, specifically in versions through 0.2.1. The issue arises from the unsafe use of the eval() function in the file premsql/agents/baseline/workers/followup.py. This vulnerability allows for code injection by manipulating the output of a language model, which is then executed on the server.
It is recommended to avoid using eval() for parsing data. Instead, use json.loads() to safely parse JSON strings and ensure that the language model outputs valid JSON.
