How to Fix GHSA-9cp7-j3f8-p5jx

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

github.com/daptin/daptin fixed: 0.12.0 
Upgrade github.com/daptin/daptin to 0.12.0
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 github.com/daptin/daptin

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9cp7-j3f8-p5jx, inspect your project dependencies for Github.com/daptin/daptin:

inspect dependencies for github.com/daptin/daptin

Analyze the terminal output to locate any version of Github.com/daptin/daptin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.0), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Github.com/daptin/daptin, 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 `cloudstore.file.upload` action in `server/actions/action_cloudstore_file_upload.go` writes user-supplied filenames directly to disk without proper validation. This allows unauthenticated attackers to perform path traversal and zip slip attacks, leading to arbitrary file write and potential remote code execution. **CVSS Score:** 10.0 Critical **CVSS Vector:** CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H **CWE:** CWE-22 (Path Traversal) ### Patches Upgrade to a patched version once released. The vulnerability affects all versions <= v0.11.3 (latest). ### Workarounds Restrict access to the cloudstore.file.upload action through authentication and authorization controls until a patch is available.
