An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18141 in the wild and no public exploit code.\n\nAffected product: Red Hat Ansible Automation Platform 2. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-18141/ (Markdown: https://insights.sbomify.com/CVE-2026-18141/index.md)","id":"CVE-2026-18141","markdown":"https://insights.sbomify.com/CVE-2026-18141/index.md","name":"CVE-2026-18141","record":{"aliases":["GHSA-9cwv-qxgx-ff4x"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ansible Automation Platform","requires_auth":"none","summary":"Unauthenticated attackers can bypass mTLS authentication in Ansible Event-Driven Ansible by forging HTTP headers, allowing injection of arbitrary events to trigger workflows.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A flaw was found in aap-gateway, a component of Ansible Automation Platform's Event-Driven Ansible (EDA). An unauthenticated remote attacker can bypass mutual Transport Layer Security (mTLS) authentication for event streams. This is achieved by manipulating the event stream URL and forging the HTTP Subject header. The system also inadvertently discloses the expected certificate subject in error messages, which simplifies the attack.
