Name of the Vulnerable Software and Affected Versions OpenHarness versions prior to commit dd1d235

Description Remote gateway users with chat access can read arbitrary files by supplying path traversal sequences to the '/memory show' slash command. Attackers can manipulate the path input parameter to escape the project memory directory and access sensitive files accessible to the OpenHarness process due to a lack of filesystem containment validation.

Recommendations Update to commit dd1d235 or a newer version. As a temporary workaround, restrict access to the '/memory show' slash command.
