Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required. NOTE: the vendor's position is that untrusted data is not an intended use case. The product's behavior will not be changed because some users rely on deserialization of trusted data.","published_at":"2020-01-02T00:00:00Z","last_modified_at":"2026-10-07T19:17:10.483000Z","cvss_v3_score":9.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-502"],"nvd_references":["https://www.tenable.com/security/research/tra-2016-20","https://raw.githubusercontent.com/distributedweaknessfiling/cvelist/master/2016/1000xxx/CVE-2016-1000027.json","https://security-tracker.debian.org/tracker/CVE-2016-1000027","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-1000027","https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-579669626","https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-582313417","https://spring.io/blog/2022/05/11/spring-framework-5-3-20-and-5-2-22-available-now","https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-744519525","https://security.netapp.com/advisory/ntap-20230420-0009/"],"vuln_status":"Modified","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-10-08T03:38:59.280078Z"},"effective_severity":"CRITICAL","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"vmware","vendor_name":"VMware","product_slug":"spring-framework","product_name":"Spring Framework","version_start":null,"version_start_inclusive":null,"version_end":"6.0.0","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:a:vmware:spring_framework:*:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.tenable.com/security/research/tra-2016-20","source_type":"MISC","tags":[]},{"url":"https://raw.githubusercontent.com/distributedweaknessfiling/cvelist/master/2016/1000xxx/CVE-2016-1000027.json","source_type":"MISC","tags":[]},{"url":"https://security-tracker.debian.org/tracker/CVE-2016-1000027","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-1000027","source_type":"MISC","tags":[]},{"url":"https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-579669626","source_type":"MISC","tags":[]},{"url":"https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-582313417","source_type":"MISC","tags":[]},{"url":"https://spring.io/blog/2022/05/11/spring-framework-5-3-20-and-5-2-22-available-now","source_type":"MISC","tags":[]},{"url":"https://github.com/spring-projects/spring-framework/issues/24434#issuecomment-744519525","source_type":"MISC","tags":[]},{"url":"https://security.netapp.com/advisory/ntap-20230420-0009/","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2020-01-02T00:00:00Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-10-07T20:37:29.225448Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-10-07T20:37:29.225448Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-10-07T20:37:29.225448Z","label":"CVSS score revised","source":"cvelistv5"}]}
