{"cve":"CVE-2026-54723","nvd":{"published":"2026-09-14T18:17:53.703","modified":"2026-09-30T19:57:08.043","status":"Deferred","description":"devpi is a Python package index staging server and packaging, testing, and release tool. Prior to 6.20.2 and 7.0.0b3, a server configured with the primary or deprecated master role allows an unauthenticated, modified GET request to the +changelog route because verify_primary does not reject a missing identity and therefore fails to require ReplicaIdentity. The response can disclose complete database content, including Argon2 password hashes and identifiers and salts for devpi-tokens; exposed hashes may be subject to dictionary attacks, and public tokens may assist attempts to derive the server secret. Large responses can also consume significant CPU, input/output capacity, and bandwidth. Servers using the standalone role are not exposed through replication, and an instance served exclusively through nginx with devpi-lockdown redirects the request to login with no known exploit. This issue is fixed in devpi-server versions 6.20.2 and 7.0.0b3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","score":6.5},"cwes":["CWE-304"],"references":["https://github.com/devpi/devpi/commit/b4ea49fed4a6233d63f8509c3bf7efafc9b2db17","https://github.com/devpi/devpi/releases/tag/server-6.20.2","https://github.com/devpi/devpi/security/advisories/GHSA-m5pq-69xg-vcq3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-54723","score":0.00434,"percentile":0.37434,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-m5pq-69xg-vcq3","url":"https://osv.dev/vulnerability/GHSA-m5pq-69xg-vcq3","summary":"devpi-server may leak database contents","modified":"2026-08-19T12:55:43.166235430Z","packages":[{"ecosystem":"PyPI","name":"devpi-server","purl":"pkg:pypi/devpi-server","ranges":["<6.20.2"],"fixed":["6.20.2"]}]},{"id":"PYSEC-2026-3661","url":"https://osv.dev/vulnerability/PYSEC-2026-3661","summary":"devpi-server may leak database contents","modified":"2026-08-19T12:45:06.488373956Z","packages":[{"ecosystem":"PyPI","name":"devpi-server","purl":"pkg:pypi/devpi-server","ranges":["<6.20.2"],"fixed":["6.20.2"]}]}],"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).
