TouchUp: Filesystem traversal
An unauthenticated caller can influence a local file inclusion operation through attacker-controlled file selection. The export does not identify the endpoint, path parameter, inclusion function or reachable file paths. Code execution would require a suitable file and execution context; this record does not establish that complete chain. The vector requires high attack complexity, but the additional prerequisite is not disclosed. Affected versions: < 1.4. The authoritative export identifies 1.4 as fixed for this CVE.

This CVE was published Oct 10, 2026 and is one of 1 known issue for this theme.
Update, patch or deactivate.
Update to 1.4 or a later supported release. Application-level remediation: Map accepted file identifiers to a fixed allowlist of server-side paths. Reject paths outside the intended directory after canonicalization; never pass a caller-supplied path directly to an include operation.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
