Content spoofing via manipulated cached text

Published Feb 19, 2026 · Updated Feb 19, 2026

Content spoofing in OpenText Directory Services 20.4.1 through 25.2 allows remote attackers to inject text that misleads users. The vendor identifies cache poisoning as the means of changing displayed text but has not disclosed the affected request, cache, or rendering locus. Exploitation requires network access without privileges and passive user exposure; the reported consequence is altered UI information, not data disclosure or service interruption.
