Description

This security bulletin contains information about 4 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2026-42587)

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 HttpContentDecompressor and DelegatingDecompressorFrameListener when processing compressed HTTP request bodies with Content-Encoding set to br, zstd, or snappy. A remote attacker can send a specially crafted compressed payload to cause a denial of service.

The configured maxAllocation limit is enforced for gzip and deflate, but is silently ignored for brotli, zstd, and snappy. The issue affects both HTTP/1.1 and HTTP/2 handling.


2) Improper Encoding or Escaping of Output (CVE-ID: CVE-2026-34481)

CWE-ID: CWE-116 - Improper Encoding or Escaping of Output

CVSSv4: 6.9 [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]


The vulnerability allows a remote attacker to cause downstream log processing systems to reject or fail to index affected records.

The vulnerability exists due to improper serialization of non-finite floating-point values in JsonTemplateLayout when processing log events containing a MapMessage with an attacker-controlled floating-point value. A remote attacker can supply a non-finite floating-point value to cause downstream log processing systems to reject or fail to index affected records.

Exploitation is possible only if the application uses JsonTemplateLayout and logs a MapMessage containing the attacker-controlled value.


3) Improper input validation (CVE-ID: CVE-2026-61053)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local authenticated user to execute arbitrary code.

The vulnerability exists due to improper input validation within the Diameter Gateway and SDK component in Oracle Communications BRM - Elastic Charging Engine. A local authenticated user can exploit this vulnerability to execute arbitrary code.


4) Deserialization of Untrusted Data (CVE-ID: CVE-2026-41855)

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 perform unauthorized actions.

The vulnerability exists due to unsafe deserialization in org.springframework.jms.support.converter.MappingJackson2MessageConverter and org.springframework.jms.support.converter.JacksonJsonMessageConverter when processing messages in an untrusted JMS environment. A remote attacker can send a crafted message to perform unauthorized actions.

Exploitation can lead to arbitrary class instantiation through gadget class deserialization.
