Repairit: Incorrect Privilege Assignment
CVE-2025-10644 is a critical-severity incorrect privilege assignment vulnerability in Repairit from Wondershare, with a CVSS 3.0 base score of 9.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Repairit versions: 6.5.2. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 3.1% chance of exploitation within 30 days, higher than 88% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of Repairit you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Wondershare 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.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Incorrect Privilege Assignment
A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
