Description
Description
In Eclipse Vert.x versions [5.0.0,5.0.12] or [5.1.0,5.1.9] or [5.2.0, 5.2.0], the Vert.x HTTP client relies on an SSL context for efficiency purpose, the key of this cache should reflect entirely the SSL semantics of the desired SSL properties. It is possible for a client to ask for an SSL context and obtain an SSL context with weaker properties, for instance a context with hostname validation and obtain a context ignoring hostname validation.
The impacted component is io.vertx:vertx-core.
