Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Shopware's shopware/platform and shopware/core Packagist packages are affected in versions below 6.6.10.18 and from 6.7.0.0 up to but not including 6.7.10.1. The OAuth token endpoint returns early for usernames that do not exist and only runs password verification for existing users, so response timing can reveal which administrator usernames exist. An attacker with network access to the token endpoint could use this timing difference to enumerate usernames, which could then support targeted password guessing or credential stuffing. Upgrade to 6.6.10.18, or 6.7.10.1 for the 6.7 line.
