DescriptionCVE.org

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.

AnalysisAI

Remote code execution in premAI-io premsql up to version 0.2.1 allows authenticated remote attackers to achieve arbitrary code execution through code injection via manipulation of the result argument in the eval function located in premsql/agents/baseline/workers/followup.py. Publicly available exploit code exists for this vulnerability, and the vendor has not responded to early disclosure attempts, leaving affected deployments without an official patch.

Vulnerability AssessmentAI

Risk Assessment	Despite the moderate CVSS score of 6.3, this vulnerability presents significant real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated attacker with access to a premAI-io premsql deployment (such as a legitimate user account or an attacker who has compromised valid credentials) submits a crafted SQL query or result parameter to the followup agent endpoint. The malicious input is passed to the eval() function in followup.py without sanitization, allowing the attacker to inject and execute arbitrary Python code-such as commands to exfiltrate sensitive data, modify database records, or establish a reverse shell for persistent access. …
Remediation	No vendor-released patch identified at time of analysis; the vendor was contacted early but has not responded. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
