AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the HTTP parsers were vulnerable to a request smuggling attack relating to WebSocket upgrades. If using the server-side component, an attacker may be able to execute a request smuggling vulnerability using an edge case in the WebSocket upgrade procedure. A WebSocket upgrade request with a body could cause the parser to switch protocols before the complete request body was received, leaving trailing bytes to be handled as upgraded-protocol or pipelined data rather than normal HTTP body data. This issue is fixed in version 3.14.2.

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:59135 advisory.

    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing     IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to     individual teams, while automation developers retain the freedom to write tasks that leverage existing     knowledge without the overhead. Ansible Automation Platform makes it possible for users across an     organization to share, vet, and manage automation content by means of a simple, powerful, and agentless     language.

    Security Fix(es):

    * automation-controller: notification backends allow SSRF and credential leakage (CVE-2026-71366)

    * python3.12-gitpython: Arbitrary Code Execution via Joined Short Options Bypass (CVE-2026-67324)
    * python3.12-gitpython: Arbitrary code execution via command injection due to unguarded Git options     (CVE-2026-67323)
    * python3.12-gitpython: Environment variable exfiltration via attacker-controlled clone URL     (CVE-2026-67322)
    * python3.12-gitpython: Arbitrary file overwrite and read via unsafe git option forwarding     (CVE-2026-73620)

The version of aiohttp installed on the remote host is prior to 3.14.2. It is, therefore, affected by a request smuggling vulnerability:

  - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the HTTP parsers     were vulnerable to a request smuggling attack relating to WebSocket upgrades. If using the server-side component, an     attacker may be able to execute a request smuggling vulnerability using an edge case in the WebSocket upgrade     procedure. A WebSocket upgrade request with a body could cause the parser to switch protocols before the complete     request body was received, leaving trailing bytes to be handled as upgraded-protocol or pipelined data rather than     normal HTTP body data. This issue is fixed in version 3.14.2. (CVE-2026-69243)
