No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The Hydra Booking – Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 1.2.1 via the /wp-json/hydra-booking/v1/booking/details/{id} REST endpoint. This is due to the getBookingDetails() callback only enforcing the tfhb_manage_options capability via tfhb_manage_options_permission(), without verifying that the requested booking belongs to the currently authenticated host (the lookup in getBookingDetailsData() filters solely on the booking id supplied in the URL). This makes it possible for authenticated attackers, with Hydra Host-level access and above (a role created by the plugin which grants tfhb_manage_options), to view sensitive booking records belonging to other hosts, including attendee names, emails, phone numbers, addresses, meeting details, payment method and status, transaction history, and internal notes by iterating booking IDs.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Data Freshness Timeline

(refreshed 10× in last 7d / 37× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 100 of 173 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. None are among the latest 100 rows. The 73 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
