**Vulnerability type:** Prototype Pollution **Vulnerability Location(s):** ```js # v9.1 node_modules/@intlify/message-resolver/index.js # v9.2 or later node_modules/@intlify/vue-i18n-core/index.js ``` **Description:** The latest version of `@intlify/message-resolver (9.1)` and `@intlify/vue-i18n-core (9.2 or later)`, (previous versions might also affected), is vulnerable to Prototype Pollution through the entry function(s) `handleFlatJson`. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) a the minimum consequence. Moreover, the consequences of this vulnerability can escalate to other injection-based attacks, depending on how the library integrates within the application. For instance, if the polluted property propagates to sensitive Node.js APIs (e.g., exec, eval), it could enable an attacker to execute arbitrary commands within the application's context. **PoC:** ```bash // install the package with the latest version ~$ npm install @intlify/message-resolver@9.1.10 // run the script mentioned below ~$ node poc.js //The expected output (if the code still vulner

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
