CVE-2026-73579: CWE-863 Incorrect Authorization in Apache Software Foundation Apache Syncope
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.

Technical Summary
CVE-2026-73579 is an incorrect authorization vulnerability in Apache Syncope. Search requests are converted into queries for SQL, Neo4J, or Elasticsearch/Opensearch depending on deployment. The Realms filter enforces permission-based restrictions on search results. However, for non-recursive searches, the Realms filter may be empty, effectively removing access controls and allowing unauthorized data access. This affects Apache Syncope versions >=3.0.0-M0 <=3.0.16, >=4.0.0-M0 <=4.0.7, and >=4.1.0-M0 <=4.1.2. The issue is fixed in versions 4.0.8 and 4.1.3.
Potential Impact
The vulnerability allows unauthorized users to bypass permission checks on search queries, potentially exposing data they should not access. This could lead to unauthorized information disclosure within affected deployments of Apache Syncope.
Mitigation Recommendations
Users should upgrade Apache Syncope to versions 4.0.8 or 4.1.3, where this incorrect authorization issue is fixed. No other mitigation steps are specified or required once the upgrade is applied.
