A path traversal vulnerability was found in pulpcore. The relative_path_validator function only verifies that content paths do not begin with "/" but fails to block directory traversal sequences such as "../" anywhere in the path. An authenticated administrator can craft a relative_path containing embedded traversal sequences (e.g., "looking/normal/../../../../etc/shadow") that escapes the intended export directory during FilesystemExport operations. Because the file content is also user-controlled (uploaded artifact), this allows arbitrary file write to any location writable by the Pulp service user, potentially leading to service compromise or further system exploitation.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:42150 advisory.

    Red Hat Satellite is a system management solution that allows organizations     to configure and maintain their systems without the necessity to provide     public Internet access to their servers or other client systems. It     performs provisioning and configuration management of predefined standard     operating environments.

    Security Fix(es):

      * pulpcore: relative_path_validator bypass via directory traversal in FilesystemExport (CVE-2026-12701)

      * yggdrasil-worker-forwarder: Incorrect parsing of IPv6 host literals in net/url (CVE-2026-25679)

      * yggdrasil-worker-forwarder: gRPC-Go: Authorization bypass due to improper HTTP/2 path validation     (CVE-2026-33186)

      * yggdrasil-worker-forwarder: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label     processing (CVE-2026-39821)

      * yggdrasil-worker-forwarder: Go net package: Denial of Service via long CNAME response in LookupCNAME     (CVE-2026-33811)

      * yggdrasil-worker-forwarder: golang crypto/x509: Denial of Service via excessive processing of DNS SAN     entries (CVE-2026-27145)

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:42078 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):

    * ansible-core: argument injection in ansible-galaxy role install leads to arbitrary code execution     (CVE-2026-11332)
    * automation-controller: Path traversal via malicious entry point name in pip wheel installation allows     arbitrary file overwrite (CVE-2026-8643)

    * automation-gateway: Axios: Information disclosure of proxy credentials via HTTP redirects     (CVE-2026-44486)
    * automation-gateway: Axios: Information disclosure of proxy credentials via redirect flows     (CVE-2026-44487)
    * automation-gateway: Axios: Denial of Service due to unenforced request and response size limits     (CVE-2026-44488)
    * automation-gateway: Axios: Information disclosure due to prototype pollution vulnerability     (CVE-2026-44495)
    * automation-gateway: fast-uri: URI authority bypass due to improper delimiter handling (CVE-2026-6322)
