However, no default limit is set which may lead to denial of service attacks when processing requests with very large numbers of form parameters. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.

CVE-2026-54225 [HIGH] CWE-770 CVE-2026-54225: Apache CXF allows to control the maximum attachment size via the "attachment-max-size". Prior to Apa Apache CXF allows to control the maximum attachment size via the "attachment-max-size". Prior to Apache CXF 4.2.3 and 4.1.8 and 3.6.12, there was no default placed on this size, meaning that a denial of service attack is possible if the user doesn't explicitly set the limit. Users should update to Apache CXF 4.2.3 or 4.1.8 or 3.6.12 which fixes this p

CVE-2026-107937 [HIGH] CWE-770 CVE-2026-107937: In Apache CXF, the parser for multipart/MTOM attachment part headers did not fully enforce the confi In Apache CXF, the parser for multipart/MTOM attachment part headers did not fully enforce the configured attachment-max-header-size (default 300 characters) and attachment-headers-max-count (default 500) limits. The size limit was applied only to each physical line, not to a header value built from continuation lines or to the combined values of a

CVE-2026-86463 [HIGH] CWE-400 CVE-2026-86463: Apache CXF's FIQL query parser has a vulnerability in how it searches for operators in query express Apache CXF's FIQL query parser has a vulnerability in how it searches for operators in query expressions. The search pattern can get stuck trying many combinations when it encounters a long string without an operator, causing the parser to consume excessive CPU time. An attacker can send a crafted query to make the server use up CPU resources, potenti

CVE-2026-97791 [HIGH] CWE-362 CVE-2026-97791: In Apache CXF, STSTokenValidator checks whether a SAML assertion is signed by a trusted certificate In Apache CXF, STSTokenValidator checks whether a SAML assertion is signed by a trusted certificate before deciding to send it to the STS. That result was stored in one object shared by all requests, so one request could read another's result. A remote, unauthenticated attacker could send a forged assertion signed with an untrusted certificate while le

CVE-2017-5656 [HIGH] CWE-384 CVE-2017-5656: Apache CXF's STSClient before 3.1.11 and 3.0.13 uses a flawed way of caching tokens that are associa Apache CXF's STSClient before 3.1.11 and 3.0.13 uses a flawed way of caching tokens that are associated with delegation tokens, which means that an attacker could craft a token which would return an identifer corresponding to a cached token for another user.

CVE-2026-108039 [HIGH] CWE-776 CVE-2026-108039: By default, StaxUtils placed no limit on the total number of elements or the total number of charact By default, StaxUtils placed no limit on the total number of elements or the total number of characters in an XML document. A very large request could therefore use a lot of memory and CPU during parsing, especially where CXF builds a DOM from the input (for example SAAJ or WS-Security), and could cause a denial of service when no request size limit

CVE-2012-2379 [CRITICAL] CVE-2012-2379: Apache CXF 2.4.x before 2.4.8, 2.5.x before 2.5.4, and 2.6.x before 2.6.1, when a Supporting Token s Apache CXF 2.4.x before 2.4.8, 2.5.x before 2.5.4, and 2.6.x before 2.6.1, when a Supporting Token specifies a child WS-SecurityPolicy 1.1 or 1.2 policy, does not properly ensure that an XML element is signed or encrypted, which has unspecified impact and attack vectors.
