How the CVE Works
CVE-2025-48261 is an Insertion of Sensitive Information Into Sent Data vulnerability in MultiVendorX, allowing attackers to retrieve embedded sensitive data. The flaw exists due to improper sanitization of user-supplied input in API responses, where internal system details, session tokens, or configuration parameters are inadvertently exposed. Attackers can exploit this by sending crafted requests that trigger the leakage of sensitive data in server responses, leading to unauthorized access or further exploitation.
