CVE-2026-42076
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedEvolver is a GEP-powered self-evolving engine for AI agents. Prior to version 1.69.3, a command injection vulnerability in the _extractLLM() function allows attackers to execute arbitrary shell commands on the server. The function constructs a curl command using string concatenation and passes it to execSync() without proper sanitization, enabling remote code execution when the corpus parameter contains shell metacharacters. This issue has been patched in version 1.69.3.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCommand injection vulnerability in the _extractLLM() function where user-controlled input (corpus parameter) is concatenated into a curl command string and passed to execSync() without sanitization, allowing arbitrary remote code execution via shell metacharacters.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the _extractLLM function in your codebaseSearch for the function definition _extractLLM in your source files or node_modulesAffected if The function exists in your environment
-
Determine the installed version of the affected library or productCheck your package.json, dependency lock file, or product version indicatorAffected if Version is lower than 1.69.3
-
Identify code paths that call _extractLLM with external inputTrace all invocations of _extractLLM and examine whether the corpus argument accepts data from user requests, APIs, or configuration filesAffected if The corpus parameter receives untrusted user input
-
Verify execSync is used to execute curl commands in the functionReview the _extractLLM implementation to confirm it builds a curl command string and passes it to execSyncAffected if execSync executes curl with the unsanitized corpus parameter
You are affected if the product containing _extractLLM is present at a version below 1.69.3 and user-controllable data can reach the corpus parameter in the curl command execution path.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to version 1.69.3 or later. If immediate patching is not possible, implement strict input validation and parameterized execution to prevent shell metacharacter injection in the corpus parameter.
version 1.69.3
- Upgrade Evolver to version 1.69.3 or later to address the command injection vulnerability in the _extractLLM() function
- After upgrading, verify that the _extractLLM() function no longer uses string concatenation with execSync() for the curl command construction
- Confirm that proper input sanitization is now in place for the corpus parameter before executing system commands
