CVE-2026-57583

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.
