How to Fix CVE-2022-24783

To remediate this vulnerability, upgrade all affected Deno dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

deno fixed: 1.20.3 
Upgrade deno to 1.20.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for deno

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-24783, inspect your project dependencies for Deno:

inspect dependencies for deno

Analyze the terminal output to locate any version of Deno in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.20.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Deno, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The versions of Deno between release 1.18.0 and 1.20.2 (inclusive) are vulnerable to an attack where a malicious actor controlling the code executed in a Deno runtime could bypass permission checks and execute arbitrary shell code. There is **no** evidence that this vulnerability has been exploited in the wild. This vulnerability does **not** affect users of Deno Deploy. ### Patches The vulnerability has been patched in Deno 1.20.3. ### Workarounds There is no workaround. All users are recommended to upgrade to 1.20.3 immediately --- The cause of this error was that certain FFI operations did not correctly check for permissions. The issue was fixed in [this](https://github.com/denoland/deno/pull/14115) pull request.
