If an attacker can provoke an application to read a maliciously crafted `jaxax.naming.Reference` or serialized object, they can provoke the download and execution of malicious code. Implementations of this functionality within the JDK were disabled by default behind a System property that defaults to `false`, `com.sun.jndi.ldap.object.trustURLCodebase`. However, since mchange-commons-java includes an independent implementation of JNDI derefencing, libraries (such as c3p0) that resolve references via that implementation could be provoked to download and execute malicious code even after the JDK was hardened. Mirroring the JDK patch, mchange-commons-java's JNDI functionality is gated by configuration parameters that default to restrictive values starting in version 0.4.0. No known workarounds are available. Versions prior to 0.4.0 should be avoided on application CLASSPATHs.

The version of Oracle Business Intelligence Enterprise Edition (OAS) 7.6.0.0.0 installed on the remote host is affected by multiple vulnerabilities as referenced in the April 2026 CPU advisory.

  - mchange-commons-java, a library that provides Java utilities, includes code that mirrors early     implementations of JNDI functionality, including support for remote `factoryClassLocation` values, by     which code can be downloaded and invoked within a running application. If an attacker can provoke an     application to read a maliciously crafted `jaxax.naming.Reference` or serialized object, they can provoke     the download and execution of malicious code. Implementations of this functionality within the JDK were     disabled by default behind a System property that defaults to `false`,     `com.sun.jndi.ldap.object.trustURLCodebase`. However, since mchange-commons-java includes an independent     implementation of JNDI derefencing, libraries (such as c3p0) that resolve references via that     implementation could be provoked to download and execute malicious code even after the JDK was hardened.
    Mirroring the JDK patch, mchange-commons-java's JNDI functionality is gated by configuration parameters     that default to restrictive values starting in version 0.4.0. No known workarounds are available. Versions     prior to 0.4.0 should be avoided on application CLASSPATHs. (CVE-2026-27727)

  - Eclipse Jersey 2.28 to 2.33 and Eclipse Jersey 3.0.0 to 3.0.1 contains a local information disclosure     vulnerability. This is due to the use of the File.createTempFile which creates a file inside of the system     temporary directory with the permissions: -rw-r--r--. Thus the contents of this file are viewable by all     other users locally on the system. As such, if the contents written is security sensitive, it can be     disclosed to other local users. (CVE-2021-28168)

  - In Connect2id Nimbus JOSE+JWT before 9.37.2, an attacker can cause a denial of service (resource     consumption) via a large JWE p2c header value (aka iteration count) for the PasswordBasedDecrypter     (PBKDF2) component. (CVE-2023-52428)

The version of Oracle Business Intelligence Enterprise Edition (OAS) 8.2.0.0.0 installed on the remote host is affected by multiple vulnerabilities as referenced in the April 2026 CPU advisory.

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Platform Security (Eclipse Jersey)). Supported versions that are affected are 7.6.0.0.0 and     8.2.0.0.0. Easily exploitable vulnerability allows low privileged attacker with logon to the     infrastructure where Oracle Business Intelligence Enterprise Edition executes to compromise Oracle     Business Intelligence Enterprise Edition. Successful attacks of this vulnerability can result in     unauthorized access to critical data or complete access to all Oracle Business Intelligence Enterprise     Edition accessible data. (CVE-2021-28168)

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Platform Security (Mchange Commons Java)). Supported versions that are affected are 7.6.0.0.0     and 8.2.0.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via     LDAP to compromise Oracle Business Intelligence Enterprise Edition. Successful attacks of this     vulnerability can result in takeover of Oracle Business Intelligence Enterprise Edition. (CVE-2026-27727)

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: BI Platform Security (OpenSSL)). The supported version that is affected is 8.2.0.0.0. Easily     exploitable vulnerability allows unauthenticated attacker with network access via TLS to compromise Oracle     Business Intelligence Enterprise Edition. Successful attacks require human interaction from a person other     than the attacker. Successful attacks of this vulnerability can result in takeover of Oracle Business     Intelligence Enterprise Edition. (CVE-2025-15467)
