{"cve":"CVE-2026-92121","nvd":{"published":"2026-09-30T13:17:21.710","modified":"2026-10-06T17:22:23.020","status":"Analyzed","description":"In the WSS4J streaming (StAX) code, a signature reference using the WS-Security STR-Transform leaves an internal \"inside signed content\" flag permanently set. The WS-SecurityPolicy enforcer uses that flag to decide whether an element needs checking, so it stops evaluating SignedParts and SignedElements for the rest of the message. A policy requiring the SOAP Body to be signed is then satisfied even when the Body carries no signature, removing the protection against XML Signature Wrapping. Signature verification itself is unaffected. The DOM code is not affected. \nUsers are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4 which fix this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-693"],"references":["https://lists.apache.org/thread.html/oop9p4hpl5o9byosb1qg3z7q1sgnn4pc","http://www.openwall.com/lists/oss-security/2026/09/30/12"],"products":["apache:wss4j"],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-92121","score":0.00548,"percentile":0.45609,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
