Description

This security bulletin contains information about 2 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2026-27727)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Platform Security (Mchange Commons Java) component in Oracle Business Intelligence Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.


2) Resource exhaustion (CVE-ID: CVE-2026-18401)

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 perform a denial of service (DoS) attack.

The vulnerability exists due to the non-blocking (async) JSON parser in jackson-core bypasses the maxNumberLength constraint (default: 1000 characters) defined in StreamReadConstraints. A remote attacker can send JSON with arbitrarily long numbers through the async parser API and exhaust CPU resources, leading to a denial of service condition.
