IDOR / Access Control Helper
This tool helps test access controls and IDOR. It sends HTTP(S) requests to the same endpoint with two different sets of headers (cookies/tokens) and compares the responses. Differences in status codes, length, and response content may indicate authorization issues or IDOR. Use it only to audit your own systems or systems where you have formal permission.
Profile A - e.g. authorized user
Profile B - e.g. unauthorized user / different role
Analysis scope
Based on a simple response comparison, no obvious signs of IDOR or authorization issues were detected. Remember that this is only an auxiliary tool - a full pentest requires manual analysis of authorization logic.

IDOR Access Control Helper is a convenient browser-based tool that helps developers, testers and security teams compare server responses for two different user profiles to more quickly spot access control issues and potential IDOR vulnerabilities, always within the framework of legal and authorized security tests of their own applications.
What IDOR Access Control Helper does
IDOR Access Control Helper takes your application's URL and then sends two requests http or https to the same resource, once as profile A and once as profile B, using the Cookie and Authorization headers you provide, and then compares response codes, content length and body fragments to help spot differences and suspiciously similar responses that may indicate an access control problem.
In practice, this means you can quickly check how the same endpoint behaves for two different user types, for example an administrator and a regular account, without having to switch between multiple browsers, sessions or tools, saving time during legitimate application security testing.
- You enter the URL address of the application or API you are interested in, for example a user panel or a specific resource.
- You paste the session or authorization headers for profile A and profile B, using only legal and authorized data.
- You set the waiting time for the server response to match the scan to the speed of the application being tested.
- You click the run button and after a while you receive a summary report with information about statuses, length of responses and estimated similarity of content.
How A B analysis works in this tool
IDOR Access Control Helper normalizes the given address, ensures the correct http or https scheme and path, and then prepares a separate request for each profile with the appropriate Cookie and Authorization header, so as to reproduce as faithfully as possible two different user contexts using the same endpoint.
After receiving the response, the tool compares status codes, measures the length of the content, and, if necessary, also calculates the approximate level of body similarity, so you can quickly notice situations in which a user with a different profile sees a very similar response even though he should not have access to this data, or vice versa - when one of the profiles receives an error in the place where he should have the correct permissions.
What is IDOR Access Control Helper useful for?
Controlling access to resources in web and API applications is one of the key security elements, and vulnerabilities in this category can appear not only in complex systems, but also in seemingly simple user panels, so it is worth regularly testing the behavior of endpoints for various roles and scenarios, for example when changing account settings, working on new functions or migrating the permissions system.
IDOR Access Control Helper simplifies this process because it allows you to compare two server responses from one place and see a summary that tells you whether the observed differences or similarities look natural from the perspective of permissions logic, or whether they require additional manual analysis and perhaps changes to the application code.
Quick sanity check for access control
You can use the tool as a quick sanity check when working on new features, pasting the addresses of key endpoints and comparing the responses for a user profile with full privileges and for an account with limited access to make sure that there are no unexpected differences or overly broad access.
Support for legal security tests
Testers and security teams can use IDOR Access Control Helper as an additional workbench during legal and authorized security tests, documenting the results of response comparisons for different profiles and looking for places where the permission logic needs refinement.
Better communication between dev and security
A clear summary of statuses, response lengths and content similarity helps better explain potential access control issues to non-technical people and makes it easier to create tickets for the development team because everyone can see in black and white how the server responded to profile A and profile B.
How to use IDOR Access Control Helper step by step
The tool's interface has been designed so that in a few simple steps you can paste the address, add session headers for two profiles and run a comparison, so even when working on the application on a daily basis, you do not have to switch between many tabs and tools to perform a basic permissions logic test.
- Copy the URL of the resource you want to test, for example an account details view, user panel or API endpoint.
- Paste the address into the url field in the IDOR Access Control Helper, letting the application take care of the schema and path automatically.
- In the Profile A section, paste the appropriate Cookie and Authorization headers, which represent the first legally logged in user profile.
- In the Profile B section, paste different Cookie and Authorization headers, for example for a lower privileged account or a test account.
- Set the wait time for the server response to match the conditions in your application and click the start scan button.
- After a while, you will see a summary with status codes, the length of the response content and an optional body similarity assessment, as well as a list of detected issues for further manual analysis.
What exactly does the IDOR Access Control Helper report show
After the scan is completed, the tool generates a report that clearly collects the most important information about the responses for profile A and profile B, so you can quickly assess whether the application behavior is consistent with expectations in terms of access control.
Response summary A B
- Status code for profiles A and B- allows you to immediately notice situations where one request ends with success and the other with an error in the 4xx range or vice versa.
- Response length in bytes- indicates whether the responses differ significantly in size, which is an additional hint when analyzing content.
- Estimated body similarity- if you enable content comparison, the tool will indicate the approximate percentage of similarity between the answers.
- List of detected issues- the report may highlight suspicious asymmetries that are worth analyzing manually in the context of the permissions logic.
Reply content analysis made easy
- Preview of unique tokens in the response content for profiles A and B, based on a shortened body fragment.
- A quick preview of response snippets for both profiles, making it easy to quickly spot differences in text or data.
- Ability to check raw http headers for profile A and B, which helps in analyzing differences in policies, cache or error messages.
- Clear division into columns A and B, making it easier to compare context details of both profiles without additional window switching.
