{"schema":"threatline.record/2","record":{"id":"CVE-2026-104712","aliases":[],"summary":"Apache Struts: Disproportionate response size when rendering BigDecimal request parameters","details":"Asymmetric resource consumption (amplification) vulnerability in Apache Struts. 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.","categories":["Frameworks"],"product":"Apache Struts","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104712","source_modified_at":"2026-10-06T14:10:31.329Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache Struts","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"2.5.14","lessThanOrEqual":"2.5.33","versionType":"semver"},{"status":"affected","version":"6.0.0","lessThanOrEqual":"6.11.0","versionType":"semver"},{"status":"affected","version":"7.0.0","lessThanOrEqual":"7.3.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00948,"percentile":0.60844,"score_date":"2026-10-23"},"published_at":"2026-10-05T18:35:41.767Z","modified_at":"2026-10-06T14:10:31.329Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104712","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T14:10:31.329Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104712","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://cwiki.apache.org/confluence/display/WW/S2-076","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-06T14:09:49.658503Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-06T14:10:31.329Z","content_hash":"ed5da40bc83f295d96092523e7f9cc0661db1ff56a1640af8bb7bf983bd9944a"}}
