CVE-2026-71569CVE-2026-71569

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 gi
