Workarounds und Korrekturmaßnahmen
| CVE ID | Workaround and Mitigation |
| CVE-2026-40634 | To mitigate this vulnerability, the security recommendation is to use a dedicated logging target bucket and do not grant general users write access to that bucket. This prevents a user from creating conflicting objects in the log destination and preserves logging integrity.Operational guidance:Dedicated target logging bucket: Configure a specific, dedicated logging bucket as the logging target bucket (separate from source buckets).ACL / permissions: Do NOT grant WRITE access on the logging bucket to non-admin or non-source-bucket-owners.Integrity / immutability: If immutable retention is required, enable S3 Lock on the dedicated logging bucket (and use appropriate retention governance/compliance settings per your deployment policy).With the above configuration, malicious users cannot pre-create objects in the LogKey path (including using the source bucket name) to block LogCache log dump, and cannot manually insert custom data into the logging destination. |
