Summary

CVE-2025-61728 is a medium-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Golang Go. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 47th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability) — see the control section below for these in your framework.

Vulnerability Data

archive/zip uses a super-linear file name indexing algorithm that is invoked the first time a file in an archive is opened. This can lead to a denial of service when consuming a maliciously constructed ZIP archive.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

The vulnerability enables an application exhaustion flood (T1499.004) via a crafted ZIP archive that triggers a super-linear file name indexing algorithm when the first file is opened, resulting in denial of service.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly limits effects of resource-exhaustion DoS triggered by malicious ZIP archives.

prevent

Enforces resource quotas/prioritization so super-linear ZIP indexing cannot starve the system.

prevent

Validates or sanitizes untrusted archive inputs before the vulnerable indexing routine runs.

Monitoring capacity and taking action to maintain availability directly reduces unchecked resource allocation.

detects

Baseline comparison of CPU, memory and bandwidth usage helps surface uncontrolled resource allocations before they cause service degradation.

prevents

Capacity projections and elasticity measures ensure that allocation requests are bounded and can be throttled, reducing the window in which an attacker can force unbounded resource reservations.

mitigates

Defining retention periods and deletion schedules for backup copies prevents indefinite accumulation of data on storage media without corresponding resource-management controls.

mitigates

Architectural redundancy and automatic failover limit the impact of an attacker who forces excessive allocations, because spare capacity can absorb the load until the primary instance recovers.

none

Documented incident response procedures that include activation of continuity plans and controlled recovery help ensure that resource consumption triggered by an incident is bounded and managed rather than left unbounded.

none

Mandating tested continuity procedures that preserve or replace resource-limiting controls prevents an attacker from exploiting the absence of throttling mechanisms during an outage.
