CVE-2026-0240

Authenticated vault secret disclosure and user impersonation

Published May 13, 2026 · Updated May 13, 2026

Information disclosure in Palo Alto Networks Trust Protection Foundation allows remote authenticated users to obtain sensitive server vault data. Palo Alto Networks has not disclosed which vault interface or operation returns protected data to an insufficiently authorized authenticated account. Low privileges and adjacent-network access are required, but no special configuration is needed; exposed data enables user impersonation and arbitrary configuration changes.
