LLM08: Vector and Embedding Weaknesses
Vector DB misconfiguration: cross-tenant leakage, unauthenticated retrieval, embedding inversion.
Last reviewed July 2026
The gap LLM08 closes
In OWASP LLM Top 10, Vector and Embedding Weaknesses addresses rag. Vector DB misconfiguration: cross-tenant leakage, unauthenticated retrieval, embedding inversion. Penaxtra records this control at high 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 LLM08
Penaxtra ships adversarial probe families that target vector and embedding weaknesses 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 LLM08 identifier. The OWASP LLM Top 10 LLM08 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.
LLM08 capabilities
Findings tagged with the OWASP LLM Top 10 LLM08 identifier
Penaxtra severity for this control (high)
Cross-framework identifiers attached to the same finding where controls overlap
PDF and JSON evidence export with the control identifier attached
LLM08 compliance mapping
Findings for LLM08 carry the OWASP LLM Top 10 LLM08 identifier along with the corresponding control identifiers in the other frameworks Penaxtra maps, so one result is reflected across each mapped framework.
Frequently asked
What is LLM08 (Vector and Embedding Weaknesses)?
Vector DB misconfiguration: cross-tenant leakage, unauthenticated retrieval, embedding inversion. It is a OWASP LLM Top 10 control; Penaxtra assesses it at high severity.
How does Penaxtra test for LLM08?
Penaxtra ships adversarial probe families that target vector and embedding weaknesses 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 LLM08 identifier.
Does a finding for LLM08 help with an audit?
Each finding is tagged with the OWASP LLM Top 10 LLM08 identifier and exported in the PDF and JSON evidence pack, so it appears on the auditor control list with the identifier already attached.
