Advisory Summary

CVE-2026-88069 is a CRITICAL security vulnerability vulnerability (CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-88069

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-2026-88069, 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. 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

Pandora contains a path traversal vulnerability in its archive extraction worker. When processing a specially crafted archive or disk image, attacker-controlled file paths could be used without ensuring that the resulting destination remained within the intended extraction directory. An attacker able to submit a malicious file for analysis could use path traversal sequences or crafted paths to cause extracted content to be written outside the designated extraction directory, potentially overwriting files accessible to the Pandora worker process. Successful exploitation could result in unauthorized modification of application or system files, denial of service, and potentially further compromise depending on the permissions of the Pandora process and the files that can be overwritten. The vulnerability is addressed by resolving each extraction destination path before writing and verifying that it remains below the expected extraction directory. Extraction attempts resolving outside this directory are rejected and reported as path traversal attempts.
