AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0, using ``CookieJar.load()`` with untrusted input may allow arbitrary code execution. Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications. Version 3.14.0 patches the issue. If an application does allow attacker controlled files to be loaded, a workaround on older releases would be to sanitize the files before loading.

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)
    * automation-controller: webhook status callback SSRF leaks the Git PAT (CVE-2026-71365)

The version of aioHTTP installed on the remote host is prior to 3.14.0. It is, therefore, affected by multiple vulnerabilities:

  - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0,     using CookieJar.load() with untrusted input may allow arbitrary code execution. Most applications using     this function will be doing so with the user's own data, so this is unlikely to affect many applications.
    Version 3.14.0 patches the issue. If an application does allow attacker controlled files to be loaded, a     workaround on older releases would be to sanitize the files before loading. (CVE-2026-34993)

  - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0,     cookies set with the cookies parameter on requests are sent after following a cross-origin redirect. If a     developer uses the cookies parameter on a per-request basis then sensitive data might be leaked to an     attacker if they manage to control a redirect. Version 3.14.0 patches the issue. If unable to upgrade,     using a Cookie header in the headers parameter is not vulnerable. (CVE-2026-47265)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0,
    using ``CookieJar.load()`` with untrusted input may allow arbitrary code execution. Most applications
    using this function will be doing so with the user's own data, so this is unlikely to affect many
    applications. Version 3.14.0 patches the issue. If an application does allow attacker controlled files to
    be loaded, a workaround on older releases would be to sanitize the files before loading. (CVE-2026-34993)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
