How to Fix CVE-2026-107828

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-107828, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1391: Use of Weak Credentials, where the product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Jivejdon through 5.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to access Weibo-created accounts by deriving predictable credentials from public Weibo user IDs. OAuthAccountServiceImp.transferSina() sets the password to the first four digits of the Weibo ID, letting attackers log in through normal form login to read or post as victims.
