CVE-2025-69230
Description
A flaw was found in aiohttp, an asynchronous HTTP client/server framework for asyncio and Python. A remote attacker can exploit this vulnerability by sending multiple specially crafted invalid cookies. This can trigger a storm of warning-level logs, leading to a Denial of Service (DoS) condition where the application's resources are exhausted.
Statement
This vulnerability is rated Low for Red Hat products. A flaw in aiohttp allows a remote attacker to trigger a logging storm by sending specially crafted invalid cookies, leading to resource exhaustion and a Denial of Service condition. This impact occurs if the application accesses the cookies attribute.
Mitigation
No mitigation is currently available that meets Red Hat Product Security’s standards for usability, deployment, applicability, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Other)
Log files can become so large that they consume excessive resources, such as disk and CPU, which can hinder the performance of the system.
Non-Repudiation
Technical Impact: Hide Activities
Logging too much information can make the log files of less use to forensics analysts and developers when trying to diagnose a problem or recover from an attack.
Non-Repudiation
Technical Impact: Hide Activities
If system administrators are unable to effectively process log files, attempted attacks may go undetected, possibly leading to eventual system compromise.
