An unauthenticated local attacker can modify signed GSDML content, update its manifest digest, retain the public certificate data, and leave an invalid nonempty `SignatureValue`. PLCnext Engineer prior to 2026.6 reports the package as `Valid` and selects the modified device description for import under the default policy.","cvssScore":6.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-347"],"vendors":[],"products":[],"references":[{"url":"https://www.certvde.com/en/advisories/VDE-2026-121/","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
