Engineering risk • Oege de Moor commentary, 21 October 2026
Priority is conditional on actual exposure. An asterisk highlights especially conditional exposure; these are editorial judgments, not CVSS scores.

Ten detailed reports: four shared analyses and six audience perspectives. Research reviewed 22 October 2026; the original PDF account remains below as a dated snapshot.
Research update and qualifications
OWASP’s guidance identifies risks from agentic coding tools crossing repository, tool and credential boundaries, and calls for independent review of security-critical behavior. It supports an assurance workflow. It does not verify the particular social-media anecdote in the original report or establish a universal AI-code failure rate.
OWASP Secure Coding with AI guidance · Primary engineering guidance checked; original anecdote remains qualified.
The origin of code does not prove it secure or insecure. Passing tests that repeat the implementation’s assumptions is not independent evidence of correct authorisation.

What the report establishes
The cited post warns that rapid AI coding can produce authorization and business-logic flaws. Its example describes an application exposing uploaded documents to other users. The post’s broad failure-rate claim is not used here as a universal statistic.
Impact and potential reach
Organizations deploying generated code without appropriate review and testing; actual exposure depends on each application’s data and permissions.
Required actions
Engineering owners: put security requirements into delivery workflows, test tenant isolation and authorization, review generated changes, and run continuous security checks. Treat model prompts as guidance, not enforcement.
Six perspectives on this topic
For the business manager
Make security and privacy acceptance part of the feature’s business definition. A demonstration that the intended customer can complete a task is only half the requirement. The other half is that people outside the authorised relationship cannot perform it.

For the business owner
Keep accountability with the organisation that ships the product. Faster implementation can be valuable, but the business still needs review capacity and a way to correct unsafe releases. Avoid evaluating productivity solely by code volume or feature count.

For the technical manager
Focus assurance on trust boundaries and high-consequence changes. Establish when peer review, threat modelling or specialist assessment is required, and prevent a generated test suite from being treated as its own independent approval.

For the software engineer
Start from an explicit authorisation matrix and test requests independently of the interface. Use separate users, tenants and roles, including revoked access and stale sessions. Review AI-generated changes as proposed code whose behavior you must understand.

For the customer service
Recognise reports that suggest a cross-account information problem and escalate them promptly. Do not ask the reporting customer to explore other records or send copies of another person’s documents. Preserve the minimum reference needed for the authorised investigation.

For the customer
If you unexpectedly see another person’s information, stop exploring and report the issue through the service’s official security or support channel. Do not redistribute the material or test more accounts to estimate the scope.

In this section
- AI-generated code: Evidence and scopeThe origin of code does not prove it secure or insecure. Passing tests that repeat the implementation’s assumptions is not independent evidence of correct authorisation.
- AI-generated code: Business impact and costsA feature can work correctly for its intended user while exposing another customer’s records. The business consequence depends on the reachable data and actions, not the size of the code change or the speed at which it was written.
- AI-generated code: Technical exposure and controlsIdentify security-sensitive changes and the trust boundaries they affect. Review object ownership, tenant separation, role checks, data export and the privileges available to the coding environment.
- AI-generated code: Response and recoveryRelease the feature only after an accountable reviewer accepts the security boundary and the negative tests exercise behavior beyond the happy path.
- AI-generated code: Business manager reportWhat must this feature refuse even when the user can guess another record’s identifier?
- AI-generated code: Business owner reportAre delivery targets rewarding speed while leaving nobody time to challenge the design?
- AI-generated code: Technical manager reportCould the same mistaken assumption have been copied into both the feature and its tests?
- AI-generated code: Software engineer reportWhat changes when I make the request directly instead of following the intended UI?
- AI-generated code: Customer service reportDoes this report describe a usability defect or access to information belonging to someone else?
- AI-generated code: Customer reportHow can I report this without collecting or sharing more of someone else’s information?
