Description

This security bulletin contains information about 4 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) Resource exhaustion (CVE-ID: CVE-2026-91776)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in TypeDeserializerBase._findDeserializer() and its _deserializers cache when processing attacker-influenced unknown type IDs with name-based polymorphism and a configured fallback implementation. A remote attacker can supply distinct unknown type IDs to cause a denial of service.

Exploitation requires reuse of a long-lived mapper or type deserializer across requests.


3) Improper input validation (CVE-ID: CVE-2026-101520)

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:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the NextGen Installer component in Oracle Global Lifecycle Management NextGen OUI Framework. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.


4) Improper Certificate Validation (CVE-ID: CVE-2026-8763)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass name constraints validation.

The vulnerability exists due to improper certificate validation in name constraints processing when handling rfc822Name and URI values with a trailing dot. A remote attacker can supply a crafted identifier to bypass name constraints validation.
