What it helps you do
Give developers, testers, and buyers a shared, limited list of web risk themes to discuss, train, and prioritize awareness. Meridian Space & Robotics can use it when talking about Chronos Hub’s telemetry parser, session handling, and access control, then move to verifiable requirements such as ASVS for actual testing depth.
A useful way to begin
- Read the 2025 introduction and treat the list as awareness, then pick one Chronos Hub risk to test for real.
- Keep the LLM Top 10 and prompt-injection guidance in a separate conversation from classic web risks.
- Link awareness items to SAST/DAST/SCA evidence rather than to a poster in the hallway.
- Use a requirements project such as ASVS when you need testable depth beyond awareness.
What good evidence looks like
For A03:2025 Software Supply Chain Failures, a Chronos Hub build note that lists the inventory you actually have and who may write code versus who may promote it. A poster on the wall is not that note. Chronos Hub is a synthetic example.
Other records you might already have
- A Chronos Hub test note that a 2025 awareness item was exercised in staging, with pass/fail evidence.
- A design review that explicitly says which Top 10 themes were out of scope for a given release.
Common misconceptions
We checked the ten boxes, so the application is secure.
OWASP Top 10:2025 is an awareness list of common web and application risks. Checking ten themes is not a finished test.
The Top 10 is the same thing as ASVS.
The Top 10 starts a conversation. The Application Security Verification Standard is a separate requirements project for testable depth.
The LLM Top 10 is this same list.
OWASP Top 10 for LLM Applications 2026 is a separate awareness list. Do not fold prompt injection into a web Top 10 row, and do not treat the two editions as one card. Labeled home: /learn/explainers/owasp-llm-top-10/.
