Deeper analysis
Wondershare Repairit contains an authentication bypass vulnerability resulting from incorrect permission assignment on SAS tokens. The flaw, tracked as CVE-2025-10644 and originally ZDI-CAN-26892, resides in the token handling logic and permits remote, unauthenticated attackers to access restricted functionality within the application.
An attacker can exploit the misconfigured token permissions to bypass authentication entirely and perform actions that enable a supply-chain attack, ultimately executing arbitrary code on customer endpoints that use the affected Repairit software. The vulnerability carries a CVSS 3.0 score of 9.4, reflecting network-accessible exploitation with high impact on confidentiality and integrity.
The sole referenced advisory is ZDI-25-896 from the Zero Day Initiative, which documents the issue but provides no further mitigation details in the available information. The associated EPSS score rose from a low baseline to a peak of 0.0300, indicating emerging exploitation interest after public disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Designation of a manager and policy dissemination ensures privileges are assigned according to defined roles.
Regular reviews catch incorrect privilege assignments to users, roles, or processes.
Explicitly specifying privileges and group/role memberships for accounts reduces the risk of incorrect privilege assignments.
The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.
Ensures privileges are assigned only as necessary rather than incorrectly over-granted.
