OWASP 2026 LLM Top 10: Excessive agency jumps to #3
MBC Technology Group
OWASP published its 2026 LLM Top 10 on August 3 and updated the ranking methodology by adding real incident data alongside expert voting, which pushed “Excessive Agency” up the list. Excessive Agency rose from #6 to #3. Agentic AI deployments are now expected to focus more on least-privilege tool permissions and human checkpoints for irreversible actions rather than only on prompt injection risk.
Why it matters
The newsletter highlights OWASP moving “an AI agent doing more than it's supposed to” from #6 to #3 in 2026. It attributes the jump to OWASP basing rankings on real incidents rather than guesswork.
