MediumCVSS 5.4Exploitation Probability (EPSS)
Low risk5th percentile — higher than 5% of all known CVEs
Summary
The Iptanus File Upload WordPress plugin before version 5.1.7 does not implement proper file handling when the duplicatepolicy setting is configured to "maintain both." Due to a TOCTOU race condition between the file existence check and the actual file write operation, an authenticated attacker can overwrite files uploaded by other users.
Risk Assessment
The risk is that an authenticated attacker can overwrite files uploaded by other users, potentially leading to data loss, file integrity compromise, or injection of malicious content.
Recommendation
It is recommended to immediately update the Iptanus File Upload plugin to version 5.1.7 or later, which fixes the vulnerability by implementing proper file handling and eliminating the race condition.
