An application that exposes an endpoint collecting Content Security Policy violation reports reads the submitted report into memory without bounding how much it will accept, so a single request can exhaust the heap and deny service to other users. Such endpoints are ordinarily reachable without authentication. The core distribution maps no such endpoint by default; applications that do not collect violation reports are not affected.\n\nThis issue affects Apache Struts: from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1.\n\nUsers are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue.","published_at":"2026-08-15T10:37:37.892000Z","last_modified_at":"2026-08-18T17:46:04.070000Z","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":"none","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":["CWE-400"],"nvd_references":["https://cwiki.apache.org/confluence/display/WW/S2-073"],"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":"2026-08-15T11:37:17.706780Z","updated_at":"2026-08-20T16:45:47.592807Z"},"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":"6.0.0","version_start_inclusive":true,"version_end":"6.11.0","version_end_inclusive":false,"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":"6.0.0","version_start_inclusive":true,"version_end":"6.10.0","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-struts:6.0.0:6.10.0"},{"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":"7.2.1","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-struts:7.0.0:7.2.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://cwiki.apache.org/confluence/display/WW/S2-073","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-08-15T10:37:37.892000Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-08-17T13:40:44.495097Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-08-17T13:40:44.495097Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-08-17T13:40:44.495097Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-08-17T13:40:44.495097Z","label":"CVSS score revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-08-17T13:40:44.495097Z","label":"CVSS score revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-08-17T13:40:44.495097Z","label":"CVSS score revised","source":"vulnrichment"}]}
