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.
AnalysisAI
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. …
