Description

A remote code execution (RCE) vulnerability in the /devserver/start endpoint of leonvanzyl autocoder commit 79d02a allows attackers to execute arbitrary code via providing a crafted command parameter.

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly prevents command injection in the /devserver/start endpoint by validating and sanitizing the crafted command parameter.

SI-2 Flaw Remediation good match
prevent

Ensures timely identification, reporting, and correction of the specific RCE flaw in autocoder commit 79d02a to eliminate exploitability.

AC-6 Least Privilege partial match
prevent

Limits the scope and impact of successful RCE by enforcing least privilege on the process handling the vulnerable endpoint.

Security SummaryAI

CVE-2026-30352 is a remote code execution (RCE) vulnerability affecting the /devserver/start endpoint in leonvanzyl's autocoder project at commit 79d02a. Published on 2026-04-27, it stems from CWE-77 (Command Injection) and carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Attackers can exploit it by supplying a crafted command parameter, enabling arbitrary code execution on the targeted system.

The vulnerability is exploitable remotely over the network by unauthenticated attackers with no privileges required and no user interaction needed. Successful exploitation grants high-impact access to confidentiality, integrity, and availability, allowing full RCE on the server hosting the vulnerable autocoder instance.
