What they could let someone do.

What could happen

  • Information leak

    It could give away information that should stay private, such as user details, file locations or settings, which makes other attacks easier.

    How: The software shows, sends or logs more than it should.

  • Server side request forgery

    Someone could make your server fetch addresses for them, reaching services that are meant to be private.

    How: The software fetches an address it was sent without checking where it points.

  • Missing checks

    Someone could do things only an administrator should: change settings, see private data, or give themselves more rights.

    How: Part of the software forgets to check who is asking before it does what was asked.
