# OpenText Directory Services: clickjacking lets a page trick users into clicks

OpenText Directory Services (OTDS) on Windows and Linux can be embedded in a hidden frame on another site, so a visitor can be tricked into clicking actions they did not intend. The attacker gets the user's authenticated actions in that session, not direct access to the server.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Confirm whether your deployment runs OpenText Directory Services between versions `10.5` and `26.2`
- Check whether OTDS responses set frame-restriction headers such as `X-Frame-Options` or a `frame-ancestors` CSP directive (unknown if the sources name a specific setting)

## Fix

- OpenText Directory Services `10.5` through `26.2`: unknown, the sources do not name a fixed version

## Timeline

- 2026-11-05T20:40:46+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-18159
