CVE-2023-47271 is a vulnerability that affects PKP-WAL (PKP Web Application Library) versions before 3.3.0-16, which is used in Open Journal Systems (OJS) and other products. This vulnerability occurs because the software fails to verify if the file named in an XML document is actually an image file before using it for an issue cover image through the native import/export plugin. The potential danger of this vulnerability lies in the fact that an attacker could exploit it remotely over a network without requiring any privileges or user interaction. It has a medium severity rating with a base score of 5.3 and an exploitability score of 3.9. However, the impact on confidentiality is low, and the integrity impact is also low. Remediation involves updating to version 3.3.0-16 or a later version of PKP-WAL to address this vulnerability and mitigate any potential risks it poses to organizations using the affected products.
