Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18948 in the wild and no public exploit code.\n\nAffected product: Red Hat OpenShift AI (RHOAI). 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-2026-18948/ (Markdown: https://insights.sbomify.com/CVE-2026-18948/index.md)","id":"CVE-2026-18948","markdown":"https://insights.sbomify.com/CVE-2026-18948/index.md","name":"CVE-2026-18948","record":{"aliases":["GHSA-gg2p-37pv-v7fq"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Red Hat OpenShift AI","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary code on Feast feature and registry servers via unsafe dill deserialization of stored UDFs.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"A flaw was found in Feast. The system improperly deserializes user-defined functions (UDFs) stored in its registry, which are serialized using the 'dill' library. This allows a remote attacker to store a malicious UDF, leading to unauthenticated arbitrary code execution on the feature server in default configurations. An authenticated attacker can also achieve arbitrary code execution on the registry server by bypassing authorization checks during deserialization. This vulnerability can result in cross-tenant data access and lateral movement within the system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Feast: feast: unsafe dill deserialization of registry-stored udfs — rce on feature server and registry server","id":"CVE-2026-18948","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"Odh-dashboard: odh-dashboard: clusterrole grants cluster-wide crud on secrets and rbac management resources","id":"CVE-2026-18949"},"packages":[],"prev":{"headline":"Feast: feast: authorization bypass in /materialize endpoints enables dos via unauthorized full re-materialization","id":"CVE-2026-18947"},"products":["Red Hat OpenShift AI (RHOAI)","Red Hat OpenShift AI 2.25","Red Hat OpenShift AI 3.3","Red Hat OpenShift AI 3.4"],"published":"2026-08-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-28","vendors":["Red Hat"]},"summary":"Remote attackers can execute arbitrary code on Feast feature and registry servers via unsafe dill deserialization of stored UDFs.","url":"https://insights.sbomify.com/CVE-2026-18948/"}
