As a golang dev, I dont really care about this vuln. (Not even sure how this would pan out).

but since the upgrade wont cause a regression, I thought I might as well go for this to get a better report for our service.

From our code analysis tool

Explanation

The github.com/gofiber/fiber package is vulnerable due to Improper Check or Handling of Exceptional Conditions. The readContent() function in the helpers.go file fails to properly handle errors thrown when deferring calls to File.Close(). A developer, unaware of this situation, may introduce a security risk by this unexpected behavior.

Recommendation

We recommend upgrading to a version of this component that is not vulnerable to this specific issue.
