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."}], "lastModified": "2026-10-08T19:11:24.190", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:struts:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "BCFD0E7B-5A78-4F25-A209-D8757E0EBE8A", "versionEndIncluding": "2.5.33", "versionStartIncluding": "2.5.14"}, {"criteria": "cpe:2.3:a:apache:struts:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B0839678-9096-43A2-BCE1-AA4A879C58E7", "versionEndExcluding": "6.12.0", "versionStartIncluding": "6.0.0"}, {"criteria": "cpe:2.3:a:apache:struts:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "03A3E16E-2D82-49D3-B982-6BE2E3706C29", "versionEndExcluding": "7.4.0", "versionStartIncluding": "7.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
