Update, patch or deactivate.
The authoritative export identifies 7.8.5 as fixed. Update to the applicable fixed release or a later supported release. Enforce server-side caller, object and operation permissions at the disclosed trust boundary; do not treat knowledge of identifiers or a nonce as authorization.
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.
