tomcat: Usage of vulnerable FileUpload package can result in denial of service

The MultipartStream class in Apache Commons Fileupload before 1.3.2, as used in Apache Tomcat 7.x before 7.0.70, 8.x before 8.0.36, 8.5.x before 8.5.3, and 9.x before 9.0.0.M7 and other products, allows remote attackers to cause a denial of service (CPU consumption) via a long boundary string.

Apache Commons FileUpload, Apache Tomcat: FileUpload DoS with excessive parts

Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. Note that, like all of the file upload limits, the new configuration option (FileUploadBase#setFileCountMax) is not enabled by default and must be explicitly configured.

CVE-2026-87830

Apache WSS4J: Streaming WS-SecurityPolicy validation may skip element-protection checks.

In the StAX streaming WS-SecurityPolicy validator, certain relative or unsupported XPath expressions can be converted into paths that never match the actual XML element path. A remote SOAP peer may therefore send a required element without the expected signature or encryption. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.

Apache WSS4J: WSS4J EncryptedHeader child confusion causing wrong protected-header selection

WSS4J EncryptedHeader child confusion could promote an attacker-controlled plaintext element as the decrypted header, leading to incorrect confidentiality coverage and possible policy bypass. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.

CVE-2026-92121

Apache WSS4J: WS-SecurityPolicy signature checks skipped in the streaming code after an STR-Transform reference

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.  Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4 which fix this issue.

CVE-2026-95616

Apache WSS4J: Unauthenticated denial of service via integer overflow in DER parsing of X.509 certificate extensions

An integer overflow in WSS4J's DER bounds check lets an oversized allocation pass validation. An unauthenticated attacker can send a SOAP message carrying an X.509 certificate whose SubjectKeyIdentifier extension declares a length of 0x7FFFFFFF; WSS4J decodes this while resolving the signature's key reference, before the message is authenticated, so an eleven-byte extension triggers a 2 GB allocation. Repeated requests exhaust server memory. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
