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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-532"],"references":["https://github.com/hyperledger/fabric-chaincode-java/security/advisories/GHSA-wg5x-3g47-v38r"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-45581","score":0.00106,"percentile":0.01092,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wg5x-3g47-v38r","url":"https://osv.dev/vulnerability/GHSA-wg5x-3g47-v38r","summary":"fabric-chaincode-java: TLS Private Key Password Disclosed in INFO Startup Logs in Chaincode-as-a-Service Mode","modified":"2026-06-09T13:30:19.031100274Z","packages":[{"ecosystem":"Maven","name":"org.hyperledger.fabric-chaincode-java:fabric-chaincode-shim","purl":"pkg:maven/org.hyperledger.fabric-chaincode-java/fabric-chaincode-shim","ranges":[">=2.3.1 <2.5.10"],"fixed":["2.5.10"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
