CVE-2026-73236: CWE-863 Incorrect Authorization in Apache Software Foundation Apache Syncope
CVE-2026-73236 is an incorrect authorization vulnerability in Apache Syncope affecting 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. The issue arises because delegated administration security checks rely on prefix matching of Realm names, causing sibling Realms with names starting with the same string to be indistinguishable. This leads to incorrect authorization decisions. Fixed versions 4.0.8 and 4.1.3 address this flaw.
AI Analysis
Technical Summary
Apache Syncope contains an authorization flaw (CWE-863) where delegated administration checks use prefix matching on Realm names. This incorrect implementation causes sibling Realms whose names begin with the same string to be treated as indistinguishable, resulting in improper authorization enforcement. The vulnerability affects Syncope versions from 3.0.0-M0 up to 3.0.16, 4.0.0-M0 up to 4.0.7, and 4.1.0-M0 up to 4.1.2. Upgrading to versions 4.0.8 or 4.1.3 mitigates the issue.
Potential Impact
The vulnerability can lead to incorrect authorization decisions in delegated administration, potentially allowing users to access or manage resources in sibling Realms they should not have permissions for. This undermines the security model based on Realm hierarchy and prefix matching, possibly resulting in unauthorized administrative actions.
Mitigation Recommendations
Users should upgrade Apache Syncope to version 4.0.8 or 4.1.3, where this authorization issue is fixed. No other mitigation is indicated by the vendor advisory.
