EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.5 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 99% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

fabric-chaincode-java is a Java based implementation of Hyperledger Fabric chaincode shim APIs. From version 2.3.1 to before version 2.5.10, when chaincode is deployed in chaincode-as-a-service mode with TLS enabled, the chaincode server INFO level logging includes the TLS private key password in plaintext. An attacker with access to the chaincode server logs could recover the TLS private key password. If the attacker can also obtain the TLS private key, they could impersonate the chaincode server. This issue has been patched in version 2.5.10.
