Path traversal in Lenovo Personal Cloud Storage devices allows authenticated remote attackers to move or access files belonging to other users on the same device, enabling unauthorized data disclosure and modification across user boundaries. Affects multiple product lines including Personal Cloud (T1, T2, T2S, T2Pro, X1, X1S, A1, A1S) and Home Storage Hub (T20, X20). CVSS 8.6 reflects high confidentiality and integrity impact with low attack complexity. No active exploitation confirmed in CISA KEV at time of analysis, and EPSS data not available for this 2026 CVE identifier.

Remote command execution in Lenovo Personal Cloud Storage devices (T1, T2, T2S, T2Pro, X1, X1S, A1, A1S, and Home Storage Hub T20/X20) allows authenticated users on the local network to execute arbitrary commands via OS command injection (CWE-78). The CVSS v4.0 score of 8.7 reflects complete system compromise potential (VC:H/VI:H/VA:H) through network attack with low complexity but requiring low-privilege authentication (AV:N/AC:L/PR:L). No evidence of active exploitation (not in CISA KEV) or public exploit code identified at time of analysis. Lenovo has issued advisories including end-of-life notices for certain models (T1), indicating some affected products may not receive patches.
