An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java `SignedObject` object to the Jenkins CLI, that would be deserialized using a new `ObjectInputStream`, bypassing the existing blacklist-based protection mechanism. We're fixing this issue by adding `SignedObject` to the blacklist. We're also backporting the new HTTP CLI protocol from Jenkins 2.54 to LTS 2.46.2, and deprecating the remoting-based (i.e. Java serialization) CLI protocol, disabling it by default.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","base_score":9.8,"base_severity":"CRITICAL","attack_vector":"NETWORK","privileges_req":"NONE","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-502"],"in_kev":true,"kev_date_added":"2025-10-02","kev_ransomware":false,"epss_score":0.99679,"epss_percentile":0.99951,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T08:42:37.921061+00:00","first_seen":"2018-01-29T17:29:00.193000+00:00","kev_first_seen":"2025-10-02T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["jenkins","oracle"],"products":["communications_cloud_native_core_automated_test_suite","jenkins"],"affected":[{"vendor":"jenkins","product":"jenkins","ranges":["≤ 2.56","≤ 2.46.1"]},{"vendor":"oracle","product":"communications_cloud_native_core_automated_test_suite","ranges":["1.9.0"]}]}
