{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/69749?format=json","vulnerability_id":"VCID-7rrj-tgy7-zqhn","summary":"RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the internode RPC layer authenticates every request with an HMAC-SHA256 signature using a shared secret. The function that produces this secret, get_shared_secret() in crates/ecstore/src/rpc/http_auth.rs, falls back to the public, source-tree-embedded DEFAULT_SECRET_KEY = \"rustfsadmin\" when neither the RUSTFS_RPC_SECRET environment variable nor the global S3 secret key has been configured. This vulnerability is fixed in 1.0.0-beta.2.","aliases":[{"alias":"CVE-2026-45039"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-45039","reference_id":"","reference_type":"","scores":[{"value":"0.00054","scoring_system":"epss","scoring_elements":"0.17407","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00054","scoring_system":"epss","scoring_elements":"0.17571","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-45039"},{"reference_url":"https://github.com/rustfs/rustfs/security/advisories/GHSA-r5qv-rc46-hv8q","reference_id":"GHSA-r5qv-rc46-hv8q","reference_type":"","scores":[{"value":"9.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:T/P:M/B:A/M:M/D:T/2026-05-30T02:11:30Z/"}],"url":"https://github.com/rustfs/rustfs/security/advisories/GHSA-r5qv-rc46-hv8q"}],"weaknesses":[{"cwe_id":798,"name":"Use of Hard-coded Credentials","description":"The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data."},{"cwe_id":1392,"name":"Use of Default Credentials","description":"The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality."}],"exploits":[],"severity_range_score":"9.8 - 9.8","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-7rrj-tgy7-zqhn"}
