CVE-2025-10644
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWondershare Repairit SAS Token Incorrect Permission Assignment Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on Wondershare Repairit. Authentication is not required to exploit this vulnerability. The specific flaw exists within the permissions granted to an SAS token. An attacker can leverage this vulnerability to launch a supply-chain attack and execute arbitrary code on customers' endpoints. Was ZDI-CAN-26892.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis vulnerability in Wondershare Repairit involves incorrect permission assignment on an SAS (Shared Access Signature) token, which allows remote attackers to bypass authentication entirely. The flaw enables attackers to launch supply-chain attacks and achieve arbitrary code execution on customer endpoints without requiring any credentials.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify installed version of Wondershare RepairitCheck the application version through the software's About section, Help menu, or by right-clicking the executable file and selecting Properties to view version informationAffected if The installed version is exactly 6.5.2
-
Identify SAS token configuration filesSearch the application installation directory and user configuration folders for files containing SAS token or Shared Access Signature references - look for patterns like *.config, *.json, or token-related filesAffected if SAS token configuration files exist and are accessible within the application directories
-
Review network communication behaviorMonitor the application network traffic using a packet capture tool or network monitor to observe any outbound connections that may be using SAS token authenticationAffected if The application makes network requests that bypass normal authentication prompts or use exposed SAS tokens
-
Check for unauthorized access indicatorsReview application and system logs for any unexpected download activity, software updates, or file modifications that occurred without user initiationAffected if Log entries show software update or file download events that were not initiated by an authenticated user
A system is affected if Wondershare Repairit version 6.5.2 is installed and the application exposes SAS tokens that allow unauthenticated network access or file modifications.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataOrganizations using Wondershare Repairit should immediately check for and apply any available security updates from the vendor. Until a patch is available, network segmentation and monitoring for suspicious activity related to the software should be implemented as compensating controls.
