Network-reachable command needing a low-privilege authenticated session (PR:L, AV:N, AC:L); bypassing permissions to apply raw write batches yields high integrity/availability and limited confidentiality impact; no UI realistically required.
Primary rating from Vendor (CNA).

AnalysisAI
Privilege bypass in Apache Kvrocks exposes the internal APPLYBATCH command without proper permission enforcement, letting an authenticated low-privilege client write raw batches directly to the underlying RocksDB storage engine and bypass the server's command ACL model. The flaw (CWE-280, improper handling of permissions) carries a CVSS 4.0 base of 9.4 due to high integrity and availability impact and an irrecoverable-damage recovery rating. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated Kvrocks session at low privilege (CVSS PR:L) with network reachability to the Kvrocks server (AV:N), and the ability to invoke the APPLYBATCH command, whose authorization check is the defective control. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are moderately strong but incomplete. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who holds a valid but low-privilege Kvrocks credential (for example, a constrained application account or a tenant in a shared cluster) connects over the network and issues the APPLYBATCH command, which the server fails to gate by privilege. By submitting crafted write batches applied straight to the RocksDB engine, the attacker overwrites or corrupts keyspace data outside their authorized scope, causing irrecoverable data integrity and availability damage. … |
| Remediation | Upgrade to the fixed Apache Kvrocks release identified in the official advisory thread at https://lists.apache.org/thread/zng5lp7psgkcv9jnm9tztdlm3rmzfydl; the exact patched version is not present in the provided data and must be read from that advisory rather than invented (Patch available per vendor advisory; specific fix version not independently confirmed from input). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Apache Kvrocks deployments; audit which systems allow untrusted or low-privilege user access; implement network-level restrictions (firewall rules, VPN requirements) limiting Kvrocks server access to trusted internal networks only. …
