AnalysisAIv1 – Sep 15, 2026

Comment-injection in the OpenZeppelin Contracts Wizard code generators lets a newline character embedded in the info.securityContact or info.license option break out of the single-line // comment and be emitted as live source declarations in generated Solidity, Cairo, Stellar/Soroban, and Stylus contracts. Only integrations that populate those two fields from untrusted input and then hand the generated source to a downstream consumer are affected — the self-service web app, AI assistant, CLI, and self-hosted API all use user-supplied values and never cross that trust boundary, and shared links cannot set the fields. The flaw is integrity-only (CVSS 3.3, CWE-94): no code executes on any Wizard service, no public exploit is identified in the supplied data, and patched packages are available as @openzeppelin/wizard 0.10.11, wizard-cairo 3.0.1, wizard-stellar 0.6.2, and wizard-stylus 0.3.1.

DescriptionCVE.org

OpenZeppelin Contracts Wizard is a web application to interactively build a contract out of components from OpenZeppelin Contracts. Prior to @openzeppelin/wizard 0.10.11, @openzeppelin/wizard-cairo 3.0.1, @openzeppelin/wizard-stellar 0.6.2, and @openzeppelin/wizard-stylus 0.3.1, the setInfo code path prints info.securityContact and info.license verbatim into single-line comments in generated Solidity, Cairo, Stellar/Soroban, and Stylus source. A line terminator ends the comment and causes following input to be emitted as source declarations. Exploitation requires an integration to populate these fields from untrusted input and a user to consume the generated source; normal self-service web, AI assistant, CLI, and self-hosted API use does not cross that trust boundary, shared links cannot set the fields, and no code executes on a Wizard service. This issue affects generated-source integrity only and is fixed in versions 0.10.11, 3.0.1, 0.6.2, and 0.3.1 of the respective packages.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
