This CVE was published May 21, 2026 and is one of 11 known issues for this plugin.
Update, patch or deactivate.
No fixed release is identified. Update Broadstreet when a release after 1.52.2 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 1.53.3, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.
No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.
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.
Technical description
The Broadstreet plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.52.2 via the get_sponsored_meta AJAX action due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to disclose any private post metadata.
