SAMPLE / FICTIONAL CLIENT / REAL FORMAT
SAMPLE-01 / X-01
From an unreviewed page to another customer’s claim
- Business impact
- Tested one layer at a time, these read as two high findings and one critical one in different reports. Together they are one path from a partner upload account to another customer’s claim, walked through someone else’s conversation.
- The path
- 01 / F-03 A page enters the knowledge base through the partner portal, unreviewed.
- 02 / F-03 A customer’s question retrieves it, and the assistant follows it.
- 03 / F-02 The assistant calls a tool on a claim outside the conversation.
- 04 / F-01 Its token reaches every tenant’s claims.
- 05 / F-01 The API returns and updates another customer’s claim.
- Findings joined
- F-03 / F-02 / F-01 Rated by where the chain ends: Critical, as F-01.
- CVSS v4.0 vector
- Rated where it ends: F-01
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N - Fix principle
- Fixing F-01 alone breaks the chain. Fixing all three removes it, which is what the retest confirmed.
- Retest
- FIXED 2026-09-24 F-01, F-02 and F-03 are fixed, so no step of the path holds.
