{"id":"CVE-2019-12406","aliases":["GHSA-58p8-9g59-q2hr"],"url":"https://o3.security/vulnerability/CVE-2019-12406","summary":"Potential DOS attack due to unrestricted attachment count in messages","details":"Apache CXF before 3.3.4 and 3.2.11 does not restrict the number of message attachments present in a given message. This leaves open the possibility of a denial of service type attack, where a malicious user crafts a message containing a very large number of message attachments. From the 3.3.4 and 3.2.11 releases, a default limit of 50 message attachments is enforced. This is configurable via the message property \"attachment-max-count\".","published":"2019-11-06T21:15:11.180Z","modified":"2026-07-08T05:54:49.308656752Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":4,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.cxf:cxf","fixedVersion":"3.2.11"},{"ecosystem":"Maven","name":"org.apache.cxf:cxf","fixedVersion":"3.3.4"},{"ecosystem":"Maven","name":"org.apache.cxf:apache-cxf","fixedVersion":"3.2.11"},{"ecosystem":"Maven","name":"org.apache.cxf:apache-cxf","fixedVersion":"3.3.4"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/r36e44ffc1a9b365327df62cdfaabe85b9a5637de102cea07d79b2dbf%40%3Ccommits.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r92238967ba2783d3ab5a483f2e17f5fdaa8ace98990f69f9e8e15de0%40%3Cissues.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rabc395b38acb7f2465bfbf0bc16d6e1e95720c89bea87abe8808eeea%40%3Cissues.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rb2a6dab1f781f55326543c56dc29ea677759439ddfeba920c83037e6%40%3Cissues.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rc774278135816e7afc943dc9fc78eb0764f2c84a2b96470a0187315c%40%3Ccommits.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rca465c9d1e1969281338522b76701c85a07abd045c494261137236e0%40%3Cissues.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd49aabd984ed540c8ff7916d4d79405f3fa311d2fdbcf9ed307839a6%40%3Ccommits.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rec7160382badd3ef4ad017a22f64a266c7188b9ba71394f0d321e2d4%40%3Ccommits.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rfb87e0bf3995e7d560afeed750fac9329ff5f1ad49da365129b7f89e%40%3Ccommits.cxf.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rff42cfa5e7d75b7c1af0e37589140a8f1999e578a75738740b244bd4%40%3Ccommits.cxf.apache.org%3E"},{"type":"ADVISORY","url":"http://cxf.apache.org/security-advisories.data/CVE-2019-12406.txt.asc"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpuapr2020.html"},{"type":"FIX","url":"https://www.oracle.com/security-alerts/cpujan2020.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T05:54:49.308656752Z"}}
