PYSEC-2026-2391

Vulnerability from pysec - Published: 2026-07-13 15:46 - Updated: 2026-07-13 16:03

Details

The docker_pull module uses the realm parameter from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validation. An attacker in a man-in-the-middle position between bbot and a Docker registry could modify this header to redirect the authentication request to an arbitrary endpoint, potentially leaking authentication tokens.

Severity

3.1 (Low)

Vulnerability from osv_homebrew

Published

Modified

2026-09-09 23:43

Summary

Details

The docker_pull module uses the realm parameter from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validation. An attacker in a man-in-the-middle position between bbot and a Docker registry could modify this header to redirect the authentication request to an arbitrary endpoint, potentially leaking authentication tokens.

Severity

3.1 (Low)
