   Tool `cairo-erc20` accepts unconstrained string input· cairo-erc20unconstrained input

   The following string parameter(s) have no `maxLength` constraint: `appName`, `appVersion`, `decimals`, `name`, `premint`, `symbol`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

   fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.

   Tool `cairo-erc721` accepts unconstrained string input· cairo-erc721unconstrained input

   The following string parameter(s) have no `maxLength` constraint: `appName`, `appVersion`, `baseUri`, `name`, `symbol`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

   fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.

   The following string parameter(s) have no `maxLength` constraint: `baseUri`, `name`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

   fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.

   The following string parameter(s) have no `maxLength` constraint: `name`, `quorum`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

   fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.
