{"id":"CVE-2026-40048","aliases":["GHSA-v3vg-332r-mw99"],"url":"https://o3.security/vulnerability/CVE-2026-40048","summary":"Apache Camel PQC: Unsafe Deserialization from FileBasedKeyLifecycleManager","details":"The Camel-PQC FileBasedKeyLifecycleManager class deserializes the contents of `<keyId>.key` files in the configured key directory using java.io.ObjectInputStream without applying any ObjectInputFilter or class-loading restrictions. The cast to `java.security.KeyPair` is evaluated only after `readObject()` has already returned, so any `readObject()` side effects in the deserialized object run before the type check. An attacker who can write to the key directory used by a Camel application — for example through a path traversal into the directory, misconfigured filesystem permissions on the volume where keys are stored, a compromised key provisioning pipeline, or a symlink attack — can place a crafted serialized Java object that, when deserialized during normal key lifecycle operations, results in arbitrary code execution in the context of the application.\n\nThis issue affects Apache Camel: from 4.19.0 before 4.20.0, from 4.18.0 before 4.18.2.\n\nUsers are recommended to upgrade to version 4.20.0, which fixes the issue by replacing java.io.ObjectInputStream-based key and metadata storage with standard PKCS#8 (private key) / X.509 SubjectPublicKeyInfo (public key) Base64 JSON encoding. For users on the 4.18.x LTS releases stream, upgrade to 4.18.2.","published":"2026-04-27T07:53:54.636Z","modified":"2026-07-16T03:31:00.227876329Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.camel:camel-pqc","fixedVersion":"4.18.2"}],"fix":null,"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/04/26/6"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-40048.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-40048"},{"type":"ADVISORY","url":"https://camel.apache.org/security/CVE-2026-40048.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40048.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40048"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2463176"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-16T03:31:00.227876329Z"}}
