CVE-2026-54723— devpi: Database contents leak

Quick assessment

Affected
devpi devpi
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

devpi是devpi组织开源的一款支持私有包托管与缓存加速的Python包索引服务器。 devpi 6.20.2之前版本和7.0.0b1至7.0.0b3之前版本存在授权问题漏洞，该漏洞源于verify_primary未拒绝缺失的身份标识，导致未经验证的攻击者可通过修改的GET请求访问+changelog路由，可能泄露数据库完整内容，包括Argon2密码哈希及devpi-tokens的标识符和盐值，暴露的哈希可能遭受字典攻击，公开令牌可能有助于推导服务器密钥，大量响应还会消耗大量CPU、输入输出能力和带宽

Vulnerability Title
devpi: Database contents leak
Source: CVE Program / CVE List V5
Vulnerability 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.
