Apache Syncope has identified three critical vulnerabilities that could enable privileged administrators to execute arbitrary SQL commands, bypass Groovy sandbox protections to inject code, and hijack higher-privileged user sessions through exposed JWT access tokens This article explores vulnerabilities enable privileged. . These flaws are tracked as CVE-2026-82232, CVE-2026-77147, and CVE-2026-73178, affecting multiple Apache Syncope versions 3.0, 4.0, and 4.1 releases.
Organizations utilizing affected instances of the identity-management platform should immediately upgrade to Syncope 4.0.8 or 4.1.3, which resolve all three vulnerabilities. This type of attack involves appending additional SQL commands to a legitimate query, enabling the attacker to read, modify, or delete database records based on the application's database account permissions.
The vulnerability permits an administrator with sufficient Implementations permissions to create a malicious Groovy Command class, incorporating untrusted code within its static CommandArgs implementation. An administrator with appropriate permissions can utilize REST to obtain a list of existing access tokens, including their signed JSON Web Tokens (JWTs). Organizations should also review administrator entitlements, restrict access to Task search and implementation-management functions, and monitor REST API logs for suspicious token-enumeration activity, unusual sorting inputs, or unexpected Groovy implementation creation.
