TL;DR: Common web application vulnerabilities map to the security failures they create, from broken access control and injection to SSRF, misconfiguration, and integrity failures, giving practitioners a practical way to prioritise testing, remediation, and control design based on real breach patterns, according to INTIGRITI. The identity lesson is that application flaws often become access-control failures, not just code defects.

By the numbers:
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes and as quickly as 9 minutes in some cases.
Questions worth separating out
A: Prioritise by exploitability, exposure, and business impact, not by severity alone.
Q: Why do cryptographic changes matter to IAM and NHI programmes?
A: IAM and NHI programmes rely on certificates, signing keys, and token trust to establish who or what is authenticated.
Q: What do teams get wrong about fine-grained access control?
A: Teams often treat fine-grained access control as a coding exercise when it is really an operating model choice.
Practitioner guidance
- Map each common web flaw to its control owner Assign broken access control, authentication failures, configuration drift, and injection issues to named owners across AppSec, IAM, platform, and engineering so remediation does not stall between teams.
- Test authorization at the object level Add API and UI checks that verify every request is evaluated for entitlement to the specific object, record, or action, not just to the route or session.
- Harden exposed trust boundaries Restrict admin interfaces, metadata access, and internal service reachability with allowlists, segmentation, and service-specific network controls before attackers can pivot through SSRF or misconfiguration.

INTIGRITI's full glossary covers the operational detail this post intentionally leaves for the source:
- Per-vulnerability mitigation steps in three stages, including how the vendor frames the fix path for each flaw type.
- The full set of 20 mapped web application vulnerability entries with example-driven explanations for testing teams.
- Specific real-world breach examples tied to each vulnerability class, useful when you need a concrete reference for remediation prioritisation.
- The vendor’s own glossary framing and source links for each example if you need to trace the original context.

Web app vulnerabilities: what IAM and security teams should notice?

Application security and identity governance now overlap at the point of authorization. Many web vulnerabilities are not just code defects. They are failures in who or what is allowed to access a resource, which is why IAM and AppSec teams need a shared view of access enforcement. If object-level checks, session handling, or API authorization are weak, the application itself becomes an identity bypass surface.
A question worth separating out:
Q: How can organisations measure whether AppSec controls are working?
A: They should look for fewer repeat vulnerabilities, lower false-positive burden, faster developer adoption, and measurable reduction in high-risk bug classes. A healthy AppSec programme changes the shape of risk, not just the number of alerts. If findings remain high but exposure does not fall, the control model is not scaling.
