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: 9.2 [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]


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) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2026-2332)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to inject arbitrary HTTP requests.

The vulnerability exists due to inconsistent interpretation of HTTP requests in the chunked transfer encoding extension parser when parsing quoted strings in HTTP/1.1 chunked transfer encoding extension values. A remote attacker can send a specially crafted chunked HTTP request to inject arbitrary HTTP requests.

The issue occurs because CRLF sequences inside quoted strings are treated as chunk header terminators instead of parsing errors.


3) Improper Handling of Alternate Encoding (CVE-ID: CVE-2026-10050)

CWE-ID: CWE-173 - Improper Handling of Alternate Encoding

CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass authentication.

The vulnerability exists due to improper handling of alternate encoding in DigestAuthentication.apply() when computing Digest authentication response hashes using ISO-8859-1 encoding. A remote attacker can use a password variant in which non-Latin-1 characters are replaced with '?' characters to bypass authentication.

Successful exploitation requires knowledge of the target username and a password containing characters outside the U+00FF range.


4) Incomplete List of Disallowed Inputs (CVE-ID: CVE-2026-54513)

CWE-ID: CWE-184 - Incomplete List of Disallowed Inputs

CVSSv4: 9.2 [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]


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.
