CVE-2020-11052 — Vulnerability in sorcery — CVE Details

HIGH

Improper Restriction of Excessive Authentication Attempts in Sorcery

Published May 7, 2020Updated July 8, 2026Source: osv

Summary

### Impact Brute force vulnerability when using password authentication via Sorcery. The brute force protection submodule will prevent a brute force attack for the defined lockout period, but once expired protection will not be re-enabled until a user or malicious actor logs in successfully. This does not affect users that do not use the built-in brute force protection submodule, nor users that use permanent account lockout. ### Patches Patched as of version `0.15.0`. ### Workarounds Currently no workarounds, other than monkey patching the authenticate method provided by Sorcery or upgrading to version `0.15.0`.
