Description
This security bulletin contains information about 2 vulnerabilities.
1) Incorrect authorization (CVE-ID: CVE-2026-59889)
CWE-ID: CWE-863 - Incorrect Authorization
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to escalate privileges.
The vulnerability exists due to improper access control in UnwrappedPropertyHandler.processUnwrapped() when deserializing @JsonUnwrapped container properties under a less-privileged active view. A remote user can supply crafted JSON values for a property annotated with both @JsonView and @JsonUnwrapped to escalate privileges.
This affects the write-side authorization behavior of @JsonView during deserialization, including merge and builder-based deserialization paths.
2) Input validation error (CVE-ID: CVE-2026-75595)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to bypass mTLS requirements.
The vulnerability exists due to an incorrect offset check in io.netty.handler.ssl.SslClientHelloHandler#decode when parsing a fragmented TLS ClientHello whose handshake header spans multiple records. A remote attacker can send a specially crafted fragmented TLS ClientHello to bypass mTLS requirements.
This issue affects deployments where per-SNI SslContext selection is the only mTLS gate, the default SslContext is permissive, and no secondary peer-certificate verification exists at the application layer.
