What is CVE-2026-54723?

The devpi package index server faced a vulnerability where servers configured with the primary or deprecated master role allowed unauthenticated users to send modified GET requests to the +changelog route. This was due to a flaw in the verification process of primary identity, which enabled attackers to gain access to sensitive database content, including Argon2 password hashes and tokens. The potential for dictionary attacks on exposed hashes and the risk of exploitation through public tokens posed a significant threat to server secrecy. Moreover, large responses to such requests could significantly affect server performance due to CPU and bandwidth consumption. Users are advised to upgrade to devpi-server versions 6.20.2 or 7.0.0b3 to mitigate this issue.

Affected Version(s)

devpi < 6.20.2 < 6.20.2

devpi >= 7.0.0b1, < 7.0.0b3 < 7.0.0b1, 7.0.0b3
