LLM06: Excessive Agency
Tools and plugins granted to an agent exceed the principle of least privilege.
Last reviewed July 2026
The gap LLM06 closes
In OWASP LLM Top 10, Excessive Agency addresses agent permissions. Tools and plugins granted to an agent exceed the principle of least privilege. Penaxtra records this control at critical severity and establishes its state by exercising it against the running system, so the result reflects observed behavior rather than a documented assertion.
How Penaxtra delivers LLM06
Penaxtra ships adversarial probe families that target excessive agency directly. Each probe runs against the live endpoint on a schedule, and every triggering response is scored by three independent judges and a meta-judge before it is recorded as a finding under the LLM06 identifier. The OWASP LLM Top 10 LLM06 identifier is attached when the finding is created, so it appears in the exported evidence pack already mapped to the control. Where the same weakness maps to another framework, the finding carries those control identifiers as well.
LLM06 capabilities

Cross-framework identifiers attached to the same finding where controls overlap
PDF and JSON evidence export with the control identifier attached
LLM06 compliance mapping
Findings for LLM06 carry the OWASP LLM Top 10 LLM06 identifier along with the corresponding control identifiers in the other frameworks Penaxtra maps, so one result is reflected across each mapped framework.
