CVE-2025-52217Network attack vector

Arbitrary HTML injection via unneutralized legacy UI fields

Published Aug 26, 2025 · Updated Aug 27, 2025

HTML injection in SelectZero Data Observability Platform before 2025.5.2 allows remote attackers to inject arbitrary HTML into legacy UI fields. The legacy fields place user-supplied input into rendered UI content without adequate neutralization, but public sources do not identify the affected fields or code path. Exploitation requires a user to view the injected content; published evidence does not identify the specific data exposed or altered.
