Description
This security bulletin contains information about 5 vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2026-21953)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local authenticated user to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Xstore Mobile component in Oracle Retail Xstore Point of Service. A local authenticated user can exploit this vulnerability to gain access to sensitive information.
2) Improper input validation (CVE-ID: CVE-2026-21954)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote authenticated user to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Xstore Mobile component in Oracle Retail Xstore Point of Service. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.
3) 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.
4) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2026-34487)
CWE-ID: CWE-532 - Information Exposure Through Log Files
CVSSv4: 6.9 [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]
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to insertion of sensitive information into log output in the cloud membership for clustering component when writing log messages. A remote attacker can trigger log entries that expose the Kubernetes bearer token to disclose sensitive information.
5) 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.
