{"id":"GHSA-v3vg-332r-mw99","summary":"Camel-PQC Vulnerable to Deserialization of Untrusted Data","details":"The Camel-PQC FileBasedKeyLifecycleManager class deserializes the contents of `\u003ckeyId\u003e.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.","aliases":["CVE-2026-40048"],"modified":"2026-09-10T03:51:03.238057212Z","published":"2026-04-27T09:34:38Z","database_specific":{"cwe_ids":["CWE-502"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-05-05T21:18:38Z","nvd_published_at":"2026-04-27T09:16:01Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40048"},{"type":"WEB","url":"https://github.com/apache/camel/pull/22034"},{"type":"WEB","url":"https://github.com/apache/camel/pull/22495"},{"type":"WEB","url":"https://github.com/apache/camel/commit/5bdd0f1d3289dfa78116deec6c81083708bf432d"},{"type":"WEB","url":"https://github.com/apache/camel/commit/5f87a86f4e337efc59248d278c6a5650e73b3b7c"},{"type":"WEB","url":"https://camel.apache.org/security/CVE-2026-40048.html"},{"type":"PACKAGE","url":"https://github.com/apache/camel"},{"type":"WEB","url":"https://issues.apache.org/jira/browse/CAMEL-23200"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/04/26/6"}],"affected":[{"package":{"name":"org.apache.camel:camel-pqc","ecosystem":"Maven","purl":"pkg:maven/org.apache.camel/camel-pqc"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.18.2"}]}],"versions":["4.12.0","4.13.0","4.14.0","4.14.1","4.14.2","4.14.3","4.14.4","4.14.5","4.14.6","4.14.7","4.14.8","4.14.9","4.15.0","4.16.0","4.17.0","4.18.0","4.18.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-v3vg-332r-mw99/GHSA-v3vg-332r-mw99.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
