description

yopass versions before 14.7.0 allow attacker-controlled HTTP method values to create unbounded Prometheus metric series. An unauthenticated remote attacker can drive memory growth, potentially terminate the service, and degrade or disrupt monitoring scrapes.

mitigation

Upgrade yopass to version 14.7.0 or later. Restrict public access to the service until the upgrade is complete.

fixed in 14.7.0
