libreoffice-convert vulnerable to path traversal / arbitrary file write
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
options.fileName is used to build a filesystem path (path.join(tempDir.name, fileName)) and the caller-supplied document buffer is written there, but fileName is never reduced to a base name. A fileName containing "../" escapes the temporary directory, so a caller can write arbitrary content to an arbitrary path the process can write to (e.g. ~/.ssh/authorized_keys, an /etc/cron.d entry, or a web root).

Evidence: public source recordsAffected products
| Affected package, product or range | Fix status |
|---|---|
| Consult the referenced vendor advisory for affected versions. | Consult source advisory |
Matching a version is only one part of assessing exposure. QFinch has not assessed your environment on this public page.
Remediation
Apply the vendor-supported fixed release or mitigation, then verify the affected component is no longer reachable.
- Confirm the affected product and reachable code path exist in your environment.
- Apply the vendor-supported patch or mitigation from the primary advisory.
- Rescan the exact deployed revision and retain verification evidence.
