In addition, the \"ID only\" fallback search runs even when the private key has no `CKA_ID`, so the search template reduces to the public-key class and the ML-KEM key type and the first ML-KEM public key on the token is returned. `Encapsulate()` on the resulting key pair encrypts the fresh shared secret to that key, so its owner — not the holder of the private key the caller looked up — can recover the secret. An attacker who can open an unauthenticated session on the token and plant a public `CKK_ML_KEM` object carrying the victim's `CKA_ID`/`CKA_LABEL` receives the shared secrets for encapsulations performed through the substituted key pair, compromising the confidentiality of those secrets and of everything protected by keys derived from them. The v1 module paths have no ML-KEM support and are not affected.","state":0,"publishedAt":"2026-10-27T11:55:15.6+00:00","modifiedAt":"2026-10-27T11:55:15.6+00:00","affected":[{"ecosystem":"Vendor product","name":"crypto11","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eclipse Foundation\",\n                    \"product\": \"Eclipse KeyPont\",\n                    \"packageName\": \"crypto11\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2.0.0-rc3\",\n                            \"lessThanOrEqual\": \"2.0.0-rc8\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5,"severity":"MEDIUM"}],"references":["https://github.com/eclipse-keypont/crypto11/security/advisories/GHSA-7842-qc22-qh4x","https://github.com/eclipse-keypont/crypto11/commit/8d99b73c721c173ad85c0ca4e063c3da360a611d","https://gitlab.eclipse.org/security/cve-assignment/-/work_items/490"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115408","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115408","identifiers":["CVE-2026-115408"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
