Any request with Content-Type application/x-java-serialized-object whose body resolves to a Serializable type is read directly via readObject(). If an application using this converter on an inbound HTTP endpoint has any known Java deserialization \"gadget\" on its classpath, a remote, unauthenticated attacker can achieve arbitrary code execution.\nSpring Integration 7.1.0\nSpring Integration 7.0.0 - 7.0.5\nSpring Integration 6.5.0 - 6.5.10\nSpring Integration 6.4.0 - 6.4.12\nSpring Integration 5.5.21 and earlier","published":"2026-08-27T06:17:17.000Z","lastModified":"2026-09-02T15:40:08.000Z","status":"Analyzed","sourceIdentifier":"security@vmware.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-502"],"affected":["vmware/spring integration"],"epss":{"score":0.05914,"percentile":0.93187,"date":"2026-10-26","history":[{"date":"2026-09-24","score":0.05914,"percentile":0.92964}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (5.91%).
