Can you explain this vulnerability to me?
The vulnerability exists in the NEX-Forms – Ultimate Forms Plugin for WordPress, specifically in all versions up to and including 9.1.9. It is an Insecure Direct Object Reference (IDOR) issue found in the submit_nex_form() function. The problem arises because the plugin does not properly validate a user-controlled key, allowing unauthenticated attackers to overwrite arbitrary form entries by manipulating the 'nf_set_entry_update_id' parameter.
How can this vulnerability impact me? :
This vulnerability can allow unauthenticated attackers to overwrite arbitrary form entries within the plugin. This means attackers could potentially alter submitted data without authorization, leading to data integrity issues. Although it does not impact confidentiality or availability, the integrity of form data can be compromised, which could affect the reliability of information collected through the forms.
