OWASP Top 10:2025
This is the 2025 version of the OWASP Top 10. This version includes updates based on the latest data and security trends.
OWASP updated their Top 10 - a brand new #3
Broken access control stays NR. 1 Just the following three sink. Supply chain is a very relevant addition. And, in parts, logical. When design and injection etc go down, supply chain which has less controls goes up. I like it :) More on reddit.com

November 12, 2025OWASP is creating a top 10 dangers list for Large Language Models
Really glad to see this. LLMs are really useful when integrated into a product, but there's all kinds of new problems they introduce. As a plug, this was our approach in our feature we released in May: https://www.honeycomb.io/blog/hard-stuff-nobody-talks-about-llm#prompt_injection_is_an_unsolved_problem The output of our LLM call is non-destructive and undoable No human gets paged based on the output of our LLM call The LLM isn’t connected to our databases or any other service We parse the output of an LLM into a particular format and run validation against it By not having a chat UI, we make it annoying and difficult to “experiment” with prompt injection inputs and seeing what outputs get returned Our input textbox and allowed outputs are truncated We have rate limits per user, per day We're at least somewhat confident bad shit like customer data exfiltration won't happen. But I'm pretty positive we're going to have to react to something bad in the future. At a minimum, someone will get it to be racist somehow. More on reddit.com

We asked ourselves whether we wanted to go with a single CWE for each "category" in the OWASP Top 10. Based on the contributed data, this is what it could have looked something like: 1. Reachable Assertion 2. Divide by Zero 3. Insufficient Transport Layer Encryption 4.

I appreciate this might be controversial and I confess I am in two minds myself. OWASP top 10 seems to be moving towards a kind of yet-another management/process list and less of actual technical vulnerabilities from, say, actual code - like SQLi or XSS. I don't think the world needa another NIST CSF or ISO 27001. My 2cents/pence.
