## Summary Multiple billing paths multiplied **user-controlled quantity parameters** into the quota calculation without an upper bound or overflow-safe integer conversion. A crafted extreme value (e.g. image `n = 18446744073686646784`, a wrapped-negative accepted by a `*uint` field) makes conversions like `int(float64(quota) * n)` wrap past the int64/int32 range into a large **negative** quota. The negative quota takes effect at **settlement** (not at pre-consume), where it is equivalent to crediting the user's balance — turning a small positive balance into an enormous one. ## Timeline（UTC+8） This vulnerability was confirmed **exploited in the wild**. Response timeline (UTC+8): - **2026-07-06 23:00** — Community user @lihui12388 reported that their deployment had been exploited via this vulnerability (large negative consumption entries in logs and abnormally inflated balances). We confirmed in-the-wild exploitation and started an emergency response immediately. - **2026-07-07 01:17** — Emergency fix released as `v1.0.0-rc.18`, roughly 2 hours after the report. - **2026-07-07 (next day)** — Given the confirmed
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
