Lifecycle Timeline
2DescriptionCVE.org
A vulnerability was found in bytedance InfiniStore up to 0.2.33. The impacted element is the function purge_kv_map in the library /src/infinistore.h of the component KV Map Handler. Performing a manipulation results in inefficient algorithmic complexity. The attack requires a local approach. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Inefficient algorithmic complexity in bytedance InfiniStore up to version 0.2.33 allows a local, low-privileged attacker to partially degrade availability by triggering worst-case execution in the purge_kv_map function. The CVSS vector (AV:L/AC:L/PR:L/UI:N/A:L) confirms limited blast radius - local-only access with no confidentiality or integrity impact - but a public proof-of-concept exists per the GitHub issue tracker and is reflected in the E:P temporal modifier. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have local access to the system running InfiniStore and a low-privilege OS account (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A locally authenticated user with minimal privileges submits a crafted set of key-value entries designed to trigger worst-case algorithmic behavior in purge_kv_map during a cleanup cycle. The function iterates over the malicious map structure in a computationally expensive pattern, causing the InfiniStore process to consume excessive CPU or stall, resulting in partial service unavailability. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
