Name of the Vulnerable Software and Affected Versions OpenHarness (affected versions not specified)
Description The /issue and /pr comments slash commands lack remote invocable=False protection. This allows remote channel senders to write attacker-controlled Markdown into project context files, specifically .openharness/issue.md and .openharness/pr comments.md. This content is subsequently injected into runtime system prompts, which can persistently influence the behavior of local agents.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
