CVE-2025-46226 is a stored cross-site scripting vulnerability in the ferranfg MPL-Publisher product, affecting versions up to 2.18.0. The vulnerability is caused by improper neutralization of input during web page generation, which allows attackers to inject malicious scripts that are stored and later executed in users' browsers. The CVSS 3.1 score of 6.5 reflects a medium severity with network attack vector, low attack complexity, requiring privileges and user interaction, and impacts on confidentiality, integrity, and availability. There is no cloud service involved, no known exploits in the wild, and no patch or vendor advisory currently available.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of affected users, potentially leading to limited disclosure of information, modification of data, or disruption of service. The impact is rated medium due to the need for user interaction and privileges, and the limited scope of confidentiality, integrity, and availability impacts.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should apply general caution with input handling and consider temporary mitigations such as input validation or output encoding if feasible. Monitor vendor channels for updates and apply patches promptly once available.
