Second-order vulnerabilities occur when one application feature processes your input in a way that affects authorization in another feature.
Swipe through to learn more about second-order attacks!
#BugBounty #HackWithIntigriti #BugQuest
In some cases, they emerge from logic flaws within multi-step workflows or feature integrations where the application loses track of authorization between steps.
Today, we’re exploring an example of such a case. Swipe through to learn more!

Even when introspection is disabled, GraphQL's auto-complete error messages will suggest correct field names when you send typos.
Swipe through to learn how to extract complete API schemas from GraphQL endpoints!
#BugBounty #HackWithIntigriti #BugQuest
These external sources can reveal endpoints that haven't been referenced before in your target, but do exist and work in production.
Swipe through to learn where to search and what to look for!
#BugBounty #HackWithIntigriti #BugQuest
When you suspect undocumented endpoints to be present, it's always recommended to further enumerate your target for more endpoints & routes.
Swipe through today's post to learn where to find (& learn to utilize) API docs!
#BugBounty #HackWithIntigriti #BugQuest
Tools like LinkFinder and JSParser automate this process, but understanding what to look for can help you spot patterns that automated tools might miss.
Swipe through to see how JS files can include endpoints and how to extract them!

Swipe through to learn how to fuzz effectively and build wordlists that actually work!
#BugBounty #HackWithIntigriti #BugQuest
Swipe through to see a few examples of config files to check and what they can reveal!
#BugBounty #HackWithIntigriti #BugQuest
From common paths and API docs to JavaScript files and mobile apps, there are multiple ways to uncover hidden endpoints that may lack proper authorization checks.
Swipe through to see the main discovery techniques! 👇
#BugBounty #HackWithIntigriti #BugQuest
We'll show you how to find hidden endpoints, enumerate APIs, and uncover the resources you need to test for BAC bugs. This is also where the real fun begins! 💪

Tomorrow, we'll dive into the different authorization-level checks, and why mixing these concepts (as a developer) leads to vulnerabilities. 👀
#BugBounty #HackWithIntigriti #BugQuest
Stick with us while we’re covering the fundamentals of BAC. We promise this will help you identify missing or weak authorization checks throughout the rest of the month.
