Apache has released critical security patches for its Syncope identity and access management platform to address numerous severe vulnerabilities. The Apache Syncope vulnerabilities include remote code execution, SQL injection, privilege escalation, server-side request forgery, and information disclosure flaws affecting multiple versions of the software. Administrators are strongly encouraged to upgrade immediately to the latest patched releases.
The security updates are available in versions 4.1.2, 4.0.7, 4.1.1, 4.0.6, 4.0.4, 3.0.16, 4.0.3, and 3.0.15, collectively resolving newly discovered Common Vulnerabilities and Exposures across Syncope’s core, console, and end-user components. The vulnerabilities impact the 3.0, 4.0, and 4.1 branches, affecting versions from early milestone builds through recent stable releases. Apache does not provide binary hotfixes, requiring users to either upgrade to patched versions or rebuild installations from updated source code.
How Can Attackers Exploit Groovy Integration Flaws?
Several critical remote code execution vulnerabilities involve exploitation through Groovy integration and scriptable connectors. Attackers with sufficient privileges can leverage Groovy classes or BPMN Groovy ScriptTasks to bypass security controls and execute untrusted code directly on servers. Additionally, misuse of scripted REST and SQL connectors enables privileged users to execute arbitrary Groovy logic, resulting in post-authentication RCE. These issues are tracked under multiple CVE identifiers including CVE-2026-63071, CVE-2026-53421, CVE-2026-53405, and CVE-2026-42782.
What SQL Injection Risks Exist in Audit Functions?
A critical SQL injection vulnerability, tracked as CVE-2026-57308, affects the Audit Events search functionality. This flaw permits authenticated administrators to input unvalidated sort parameters, leading to unauthorized SQL queries against the backing database. The vulnerability impacts versions from 3.0.0-M0 to 3.0.16 and 4.0.0-M0 to 4.0.6, with fixes included in versions 4.0.7 and 4.1.2.
Can Users Escalate Their Own Privileges?
A privilege escalation flaw identified as CVE-2026-62183 exists in self-service workflows, allowing users to assign themselves roles without proper administrative approval. This effectively grants unauthorized users administrative access to the system. The vulnerability appears in the same version ranges as the SQL injection issue and is resolved in versions 4.1.2 and 4.0.7.
What Other Security Flaws Were Addressed?
Apache also patched a low-privilege authenticated SSRF vulnerability (CVE-2026-62418) that could allow crafted requests to trigger arbitrary outbound HTTP calls. Information disclosure bugs tracked as CVE-2026-42797 enable sensitive user field exposure during data reads. Web interface vulnerabilities include XML External Entity attacks (CVE-2026-23795) and cross-site scripting issues (CVE-2026-23794 and CVE-2024-45031), which can lead to credential theft and session hijacking.
The updates also address older flaws, including a hardcoded AES key (CVE-2025-65998) used for password encryption that could allow attackers with database access to decrypt stored passwords. Apache recommends all administrators upgrade to versions 4.1.2 and 4.0.7 to mitigate the most critical vulnerabilities and rigorously review user roles and entitlements, particularly in workflows and self-service functionalities.
