{"id":"CVE-2026-54723","state":"PUBLISHED","title":"devpi: Database contents leak","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.","publishedAt":"2026-09-14T17:41:23.451Z","updatedAt":"2026-09-14T18:21:50.993Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["devpi devpi"],"affected":[{"vendor":"devpi","product":"devpi","versions":[{"version":"< 6.20.2","status":"affected"},{"version":">= 7.0.0b1, < 7.0.0b3","status":"affected"}]}],"references":["https://github.com/devpi/devpi/security/advisories/GHSA-m5pq-69xg-vcq3","https://github.com/devpi/devpi/commit/b4ea49fed4a6233d63f8509c3bf7efafc9b2db17","https://github.com/devpi/devpi/releases/tag/server-6.20.2"],"weaknesses":["CWE-304"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54723.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54723","state":"PUBLISHED","datePublished":"2026-09-14T17:41:23.451Z","dateUpdated":"2026-09-14T18:21:50.993Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T23:07:33.232Z"},"containers":{"cna":{"title":"devpi: Database contents leak","descriptions":[{"lang":"en","value":"devpi is a Python package index staging server and packaging, testing, and release tool.
