When a request parameter is bound to an arbitrary-precision decimal (java.math.BigDecimal) property that is then rendered through the Struts tag library, the framework can produce a response many orders of magnitude larger than the request, allowing an unauthenticated remote attacker to exhaust server CPU and outbound network capacity with sustained low-volume traffic. Applications that do not bind request parameters to BigDecimal properties, or never render such a property through the Struts tag library, are not affected.\n\nThis issue affects Apache Struts: from 2.5.14 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0.\n\nUsers are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.","published_at":"2026-10-05T18:35:41.767000Z","last_modified_at":"2026-10-08T19:11:24.190000Z","cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","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-405"],"nvd_references":["https://cwiki.apache.org/confluence/display/WW/S2-076"],"vuln_status":"Analyzed","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":"2026-10-05T20:34:34.418187Z","updated_at":"2026-10-11T23:59:09.183734Z"},"effective_severity":"HIGH","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":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apache","vendor_name":"apache","product_slug":"struts","product_name":"Struts","version_start":"2.5.14","version_start_inclusive":true,"version_end":"2.5.33","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:apache:struts:*:*:*:*:*:*:*:*"},{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-struts","product_name":"Apache Struts","version_start":"2.5.14","version_start_inclusive":true,"version_end":"2.5.33","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-struts:2.5.14:2.5.33"},{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-struts","product_name":"Apache Struts","version_start":"6.0.0","version_start_inclusive":true,"version_end":"6.11.0","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-struts:6.0.0:6.11.0"},{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-struts","product_name":"Apache Struts","version_start":"7.0.0","version_start_inclusive":true,"version_end":"7.3.0","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-struts:7.0.0:7.3.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://cwiki.apache.org/confluence/display/WW/S2-076","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-10-05T18:35:41.767000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-10-06T14:34:34.415354Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-10-06T14:34:34.415354Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-10-06T14:34:34.415354Z","label":"CVSS score revised","source":"cvelistv5"}]}
