CVE-2025-15546: CWE-362 Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization) in Iptanus File Upload
A race condition vulnerability exists in the Iptanus File Upload WordPress plugin versions before 5.1.7 when the duplicatepolicy setting is set to "maintain both." This TOCTOU issue allows an authenticated attacker to overwrite files uploaded by other users due to improper synchronization between file existence checks and file write operations.
AI Analysis
Technical Summary
CVE-2025-15546 describes a race condition (CWE-362) in the Iptanus File Upload WordPress plugin prior to version 5.1.7. When the duplicatepolicy setting is configured to "maintain both," the plugin performs a time-of-check to time-of-use (TOCTOU) sequence that lacks proper synchronization. This flaw enables an authenticated user to overwrite files uploaded by other users by exploiting the window between the file existence check and the actual file write operation.
Potential Impact
An authenticated attacker can overwrite files uploaded by other users, potentially leading to unauthorized modification or replacement of files within the application context. This could affect data integrity and user content management within the plugin's file upload functionality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is currently available. Until a fix is released, users should consider restricting access to the file upload functionality or disabling the plugin if feasible to prevent exploitation.
