How to Fix CVE-2026-76032

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-2026-76032, 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. 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

Pydio Cells 5.0.0 through 5.0.2 returns share-link details to any authenticated user. The REST handler for GET /a/share/link/{Uuid} in idm/share/rest/handler.go reads the workspace UUID from the path, calls LinkById, and writes the result with no authorization step, whereas the sibling handler for GET /a/share/cell/{Uuid} loads the workspace and requires MatchPolicies with ResourcePolicyAction_READ, returning a not-found error so that existence is not disclosed. Nothing compensates further down: GetLinkWorkspace reaches GetOrCreateWorkspace, which issues SearchWorkspace with a query carrying no ResourcePolicyQuery, and PrepareResourcePolicyQuery returns the query unmodified when that field is nil, so the workspace service applies no policy filter. The workspace UUID is not secret, because the unauthenticated public page served for a share link embeds it as START_REPOSITORY. Any account holding a standard user role can therefore submit the UUID and receive the link hash and URL, the owner's user identifier, the hidden share user login, the permission set, the download limit and count, the target users, the expiry, and the password-required flag, while a direct read of the shared node from the same account is refused.
