The function SerializationSessionDataTranscoder.decode() calls ObjectInputStream.readObject() to deserialize a SessionData object without checking the object types. An attacker can create a malicious object, base64 encode it, and place it in the PIPPO_SESSION field of a cookie. Sending this cookie may lead to remote code execution.","published":"2018-10-23T20:29:00.797Z","modified":"2026-07-08T17:16:55.217664Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Maven","name":"ro.pippo:pippo-core","fixedVersion":"1.12.0"}],"fix":{"url":"https://github.com/pippo-java/pippo/commit/a82347d9d3358e98c89b48579d4285d807a57cc0","label":"pippo-java/pippo@a82347d"},"references":[{"type":"FIX","url":"https://github.com/pippo-java/pippo/issues/458"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-18628"},{"type":"WEB","url":"https://github.com/pippo-java/pippo/commit/a82347d9d3358e98c89b48579d4285d807a57cc0"},{"type":"WEB","url":"https://github.com/pippo-java/pippo/commit/c6b26551a82d2dd32097fcb17c13c3b830916296"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-7fm6-2qw4-g3x3"},{"type":"PACKAGE","url":"https://github.com/pippo-java/pippo"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T17:16:55.217664Z"}}
