Description
This security bulletin contains information about 4 vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2026-54512)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to instantiate arbitrary classes.
The vulnerability exists due to deserialization of untrusted data in DatabindContext._resolveAndValidateGeneric() and PolymorphicTypeValidator handling when processing polymorphic type identifiers with generic parameters during deserialization. A remote attacker can supply a specially crafted type identifier and JSON data to instantiate arbitrary classes.
Only applications that accept untrusted JSON and have polymorphic typing enabled while relying on a configured PolymorphicTypeValidator allow-list are affected.
2) Incomplete List of Disallowed Inputs (CVE-ID: CVE-2026-54513)
CWE-ID: CWE-184 - Incomplete List of Disallowed Inputs
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to instantiate non-allowlisted types.
The vulnerability exists due to incomplete list of disallowed inputs in BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray() when deserializing attacker-controlled JSON containing array subtypes. A remote attacker can supply a crafted array wrapper to instantiate non-allowlisted types.
The issue occurs because array types are allowlisted based only on whether the class is an array, without validating the array component type against the configured allowlist, and no further validator check occurs for elements when per-element type IDs are absent.
3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-54514)
CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause outbound DNS requests and disclose limited network information.
The vulnerability exists due to server-side request forgery in JDKFromStringDeserializer when deserializing untrusted JSON into a type containing an InetSocketAddress field. A remote attacker can supply a crafted hostname value to cause outbound DNS requests and disclose limited network information.
The DNS lookup occurs during readValue before application-level validation or explicit connection logic.
CWE-ID: CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to modify otherwise ignored object attributes.
The vulnerability exists due to improper control of dynamically determined object attributes in BeanDeserializerBase.createContextual() when processing case-insensitive deserialization with per-property @JsonIgnoreProperties exclusions. A remote attacker can send crafted JSON input to modify otherwise ignored object attributes.
Only applications that enable case-insensitive property matching and rely on per-property @JsonIgnoreProperties to keep a field unwritable are vulnerable.
