ReynardSec<p>A grumpy ItSec guy walks through the office when he overhears an exchange of words.</p><p>dev0: Big news - we finally upgraded every framework to the latest.<br>dev1: And the pipeline looks good: SAST, container scan, DAST... all green.<br>dev0: ItSec won't have anything to nitpick now!</p><p>ItSec (walking by): ... and BAC?<br>dev0: BAC?<br>ItSec: Broken Access Control [1]. Did you actually test for it?</p><p>dev1: What's he on about this time?</p><p>Let's learn by example: imagine an endpoint that returns a specific invoice.</p><pre><code>GET /api/invoices/123<br>Authorization: Bearer &lt;token-for-user-A&gt;<br></code></pre><p>User A legitimately fetches invoice 123. Now change only the ID:</p><pre><code>GET /api/invoices/124<br>Authorization: Bearer &lt;token-for-user-A&gt;<br></code></pre><p>If the app returns 200 with User B's data, you've got Broken Access Control (aka IDOR).</p><p>Even worse, try a write operation:</p><pre><code>PATCH /api/invoices/124<br>Authorization: Bearer &lt;token-for-user-A&gt;<br><br>{"status": "paid"}<br></code></pre><p>If that works... it's a problem.</p><p>Access control enforces who can do what on which resource. When it's broken, attackers can act outside their permissions: read others data, modify or delete it, or trigger business functions they shouldn't. In practice, this often comes from missing server-side checks that tie the caller to the resource owner (or an allowed role).</p><p>Why your shiny scanners may have missed it:</p><p>1) SAST sees code patterns, not ownership semantics (it can't deduce "invoice 124 belongs to User B").<br>2) DAST usually crawls with one session; it rarely performs cross-identity trials (User A poking at User B's data).<br>3) CI/CD "green checks" mean dependencies, images, and common vulns look fine - not that your authorization logic is correct.</p><p>What can you do?</p><p>1) Enforce checks on the server (never rely on the client): before every read/update/delete, verify the caller is the owner or has a permitted role.<br>2) Centralize authorization in a service/middleware.<br>3) Prefer opaque, unguessable IDs (UUIDs) over sequential integers, but still enforce server checks (UUIDs are not security).<br>4) Deny by default. Make allow-lists explicit.</p><p>[1] <a href="https://owasp.org/Top10/A01_2021-Broken_Access_Control/#description" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">owasp.org/Top10/A01_2021-Broke</span><span class="invisible">n_Access_Control/#description</span></a> </p><p><a href="https://infosec.exchange/tags/webdev" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>webdev</span></a> <a href="https://infosec.exchange/tags/cybersecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cybersecurity</span></a> <a href="https://infosec.exchange/tags/programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>programming</span></a> <a href="https://infosec.exchange/tags/java" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>java</span></a> <a href="https://infosec.exchange/tags/php" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>php</span></a> <a href="https://infosec.exchange/tags/nodejs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>nodejs</span></a> <a href="https://infosec.exchange/tags/javascript" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>javascript</span></a> <a href="https://infosec.exchange/tags/infosec" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>infosec</span></a></p>
