Advisory Summary

CVE-2026-88875 is a MODERATE (CVSS 4.3) security vulnerability vulnerability (CWE-359: Exposure of Private Personal Information to an Unauthorized Actor) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-88875

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-2026-88875, 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-359: Exposure of Private Personal Information to an Unauthorized Actor, where the product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected. 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

AVideo through revision c3edcc274c389816d434acadac07ee78eaf330c1 (master, 2026-08-23) incompletely sanitizes sensitive user fields in the APIName=video response. Video rows include columns joined from the video owner's user record, and API::get_api_video() calls removeSensitiveUserFields() only when the caller is neither authenticated nor using a valid API secret; it never compares User::getId() with the row's users_id. As a result, any low-privilege authenticated account can request another user's video and receive the owner's email address, account name (user), and isAdmin, canUpload and canStream flags, which are removed for guests and should be returned only to the owner or to callers with a valid API secret. No patched version was available at the time of the advisory.
