A Velocity template can be provided through Velocity templates in a configset `velocity/` directory or as a parameter. A user defined configset could contain renderable, potentially malicious, templates. Parameter provided templates are disabled by default, but can be enabled by setting `params.resource.loader.enabled` by defining a response writer with that setting set to `true`. Defining a response writer requires configuration API access. Solr 8.4 removed the params resource loader entirely, and only enables the configset-provided template rendering when the configset is `trusted` (has been uploaded by an authenticated user).","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","base_score":7.5,"base_severity":"HIGH","attack_vector":"NETWORK","privileges_req":"LOW","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-74"],"in_kev":true,"kev_date_added":"2021-11-03","kev_ransomware":false,"epss_score":0.98567,"epss_percentile":0.99922,"cap_rule_version":"0.1.1","stage":"EXECUTION","req_access":"USER","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T09:08:40.157552+00:00","first_seen":"2019-12-30T17:15:19.780000+00:00","kev_first_seen":"2021-11-03T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["apache","oracle"],"products":["primavera_unifier","solr"],"affected":[{"vendor":"apache","product":"solr","ranges":["≥ 5.0.0 and < 7.7.3","≥ 8.0.0 and < 8.4.0"]},{"vendor":"oracle","product":"primavera_unifier","ranges":["≥ 17.7 and ≤ 17.12","16.1","16.2","18.8","19.12"]}]}
