Machine-written summary

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

Barzahlen Payment Module PHP SDK (barzahlen/barzahlen-php) versions before 2.0.1 contain an observable timing discrepancy in the verify function of the webhook handling code. The source gives few details about how the timing difference could be measured or what an attacker could learn from it. Upgrade to version 2.0.1, which fixes the issue.
