Server-Side Request Forgery (SSRF) vulnerability in Apache Camel A2A component. This issue affects Apache Camel: from 4.21.0 before 4.22.2. WebhookUrlValidator classified a push notification webhook host in two places that did not agree. A host written as an IP literal was matched against a list of string prefixes that named the IPv6 unique local range fc00::/7, while a host reached through a name was resolved and the resulting address classified with the InetAddress predicates isLoopbackAddress, isAnyLocalAddress, isLinkLocalAddress and isSiteLocalAddress. Those predicates do not cover the same ground as the prefix list: isSiteLocalAddress reports the deprecated fec0::/10 block and not the fc00::/7 unique local addresses that replaced it, and the JDK carries no predicate for them at all. The same address was therefore accepted or rejected depending on how it was written, and a webhook URL whose host name resolved into fc00::/7 passed a guard that refused the identical address given as a literal. PushNotificationDispatcher then sent the push notification to that address, together with any Authorization header carried in the same configuration, whose scheme and credentials the registering caller supplies. The webhook URL arrives as TaskPushNotificationConfig.url from the caller registering the push notification, so it is attacker-controlled, and allowLocalWebhookUrls is false by default, which is the configuration in which the guard is expected to hold. The response is not relayed back to the caller who registered the configuration, so what the gap yields is a blind outbound HTTPS request from the Camel process to an internal address the guard was written to refuse; reaching a service that way additionally requires that the name resolve into fc00::/7 in the target environment, that an HTTPS service be listening on that address, and that the TLS handshake succeed for the name being requested, which is why the severity is assessed medium. The same string pre-chec
