Apache Syncope versions 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.7, and 4.1.0-M0 through 4.1.2 are vulnerable to an incorrect authorization issue that can lead to unauthorized access to sensitive data, as the Realms filter may be rendered empty for non-recursive search requests. This critical vulnerability (CVSS 9.8) poses a significant risk to organizations using affected versions, as it can compromise user permissions and data integrity. Users should prioritize upgrading to versions 4.0.8 or 4.1.3 to mitigate this risk.

Original NVD Description

Incorrect Authorization vulnerability in Apache Syncope. Any search requests are transformed into SQL, Neo4J or Elasticsearch / Opensearch queries, depending on the actual deployment configuration. An important component of such transformation is the Realms filter, which ensures that the search results are matching the requester's permissions. For non-recursive search requests it is possible that such Realms filter is rendered as empty, thus voiding any restriction on requester privileges. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.7, from 4.1.0-M0 through 4.1.2. Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.
