CVE-2026-29106 is a Cross-Site Scripting (XSS) vulnerability in SuiteCRM, affecting versions prior to 7.15.1 and 8.9.3, caused by insufficient sanitization of the return_id request parameter. This vulnerability carries a Medium severity CVSS score of 6.1, requiring user interaction but allowing an unauthenticated attacker to achieve low impact on confidentiality and integrity. Although the EPSS score is very low, indicating a low probability of exploitation, it could lead to session hijacking or defacement. There is currently no evidence of active exploitation, nor are public exploit codes or Metasploit modules available. Organizations should update to SuiteCRM versions 7.15.1 or 8.9.3 and implement a Content Security Policy (CSP) header for complete mitigation.
