{"cve":"CVE-2025-27508","nvd":{"published":"2025-03-05T22:15:35.867","modified":"2026-06-17T09:03:43.690","status":"Deferred","description":"Emissary is a P2P based data-driven workflow engine. The ChecksumCalculator class within allows for hashing and checksum generation, but it includes or defaults to algorithms that are no longer recommended for secure cryptographic use cases (e.g., SHA-1, CRC32, and SSDEEP). These algorithms, while possibly valid for certain non-security-critical tasks, can expose users to security risks if used in scenarios where strong cryptographic guarantees are required. This issue is fixed in 8.24.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-327"],"references":["https://github.com/NationalSecurityAgency/emissary/commit/da3a81a8977577597ff2a944820a5ae4e9762368","https://github.com/NationalSecurityAgency/emissary/security/advisories/GHSA-hw43-fcmm-3m5g","https://github.com/NationalSecurityAgency/emissary/security/advisories/GHSA-hw43-fcmm-3m5g"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:00:17.429720821+00:00"},"epss":{"cve":"CVE-2025-27508","score":0.0021,"percentile":0.11264,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hw43-fcmm-3m5g","url":"https://osv.dev/vulnerability/GHSA-hw43-fcmm-3m5g","summary":"Emissary May Use a Broken or Risky Cryptographic Algorithm","modified":"2026-09-10T03:50:56.899887949Z","packages":[{"ecosystem":"Maven","name":"gov.nsa.emissary:emissary","purl":"pkg:maven/gov.nsa.emissary/emissary","ranges":["<8.24.0"],"fixed":["8.24.0"]}]}],"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).
