dynaconf is a configuration management tool for Python. Prior to version 3.2.13, Dynaconf is vulnerable to Server-Side Template Injection (SSTI) due to unsafe template evaluation in the @Jinja resolver. When the jinja2 package is installed, Dynaconf evaluates template expressions embedded in configuration values without a sandboxed environment. This issue has been patched in version 3.2.13.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:34160 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-platform-ui: Axios: Denial of Service due to unenforced request and response size limits     (CVE-2026-44488)
    * automation-platform-ui: Axios: Information disclosure due to prototype pollution vulnerability     (CVE-2026-44495)
    * automation-platform-ui: fast-uri: URI authority bypass due to improper delimiter handling     (CVE-2026-6322)
    * automation-platform-ui: Axios: Arbitrary HTTP header injection via prototype pollution (CVE-2026-42035)
    * automation-platform-ui: DOMPurify: Cross-Site Scripting (XSS) via inconsistent tag sanitization     (CVE-2026-41240)
    * automation-platform-ui: protobufjs: Arbitrary code execution due to unsafe expression generation from     crafted protobuf descriptors (CVE-2026-44293)
    * python3.12-pyjwt: Authentication bypass due to forged JSON Web Tokens (CVE-2026-48526)
    * automation-controller: Dynaconf: Arbitrary code execution via Server-Side Template Injection     (CVE-2026-33154)
    * python3.12-urllib3: Information disclosure via cross-origin redirects forwarding sensitive headers     (CVE-2026-44431)
    * python3.12-urllib3: Denial of Service due to excessive HTTP response decompression (CVE-2026-44432)
