{"cve":"CVE-2026-40473","nvd":{"published":"2026-04-27T09:16:01.640","modified":"2026-10-26T22:10:00.163","status":"Modified","description":"The camel-mina component's MinaConverter.toObjectInput(IoBuffer) type converter wraps an IoBuffer in a java.io.ObjectInputStream without applying any ObjectInputFilter or class-loading restrictions. When a Camel route uses camel-mina as a TCP or UDP consumer and requests conversion to ObjectInput (for example via getBody(ObjectInput.class) or @Body ObjectInput), an attacker sending a crafted serialized Java object over the network to the MINA consumer port can trigger arbitrary code execution in the context of the application during readObject().\n\nThis issue affects Apache Camel: from 3.0.0 before 4.14.6, from 4.15.0 before 4.18.2, from 4.19.0 before 4.20.0.\n\nUsers are recommended to upgrade to version 4.20.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.6. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-502"],"references":["https://camel.apache.org/security/CVE-2026-40473.html","http://www.openwall.com/lists/oss-security/2026/04/26/8","https://access.redhat.com/security/cve/CVE-2026-40473","https://bugzilla.redhat.com/show_bug.cgi?id=2463180","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-40473.json"],"products":["apache:camel"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-40473","score":0.01188,"percentile":0.67685,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-vpr3-2659-rw55","url":"https://osv.dev/vulnerability/GHSA-vpr3-2659-rw55","summary":"Camel-MINA Vulnerable to Deserialization of Untrusted Data","modified":"2026-05-05T21:41:25.759981Z","packages":[{"ecosystem":"Maven","name":"org.apache.camel:camel-mina","purl":"pkg:maven/org.apache.camel/camel-mina","ranges":[">=3.0.0 <4.14.6"],"fixed":["4.14.6"]},{"ecosystem":"Maven","name":"org.apache.camel:camel-mina","purl":"pkg:maven/org.apache.camel/camel-mina","ranges":[">=4.15.0 <4.18.2"],"fixed":["4.18.2"]},{"ecosystem":"Maven","name":"org.apache.camel:camel-mina","purl":"pkg:maven/org.apache.camel/camel-mina","ranges":[">=4.19.0 <4.20.0"],"fixed":["4.20.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
