The Ansible plug-ins provide curated content and features to accelerate Ansible learner onboarding and streamline Ansible use case adoption across your organization.
AI Analysis
Technical Summary
An algorithmic denial of service vulnerability exists in the nanoid library's customAlphabet and customRandom functions. When these functions receive a zero-size parameter, the internal loop fails to terminate, causing an infinite loop. This leads to 100% CPU utilization and blocks the event loop in Node.js or browser contexts, effectively causing a denial of service. The vulnerability affects Red Hat Ansible Automation Platform versions including 2.20.0-0.6.hum1 and others. The vendor advisory confirms a patch is available and recommends validating input parameters to prevent zero-size values.
Potential Impact
An attacker can cause a denial of service by supplying a zero-size parameter to nanoid's customAlphabet or customRandom functions, resulting in an infinite loop that consumes CPU resources and blocks application threads. This can degrade or halt the affected application's operation.
Mitigation Recommendations
A fix is available from Red Hat. Users should apply the official patch provided by Red Hat for the affected packages. Additionally, application code should validate the size parameter passed to nanoid's customAlphabet or customRandom functions to reject or sanitize zero-value inputs before calling these functions.
