——1The Hydra Booking — Appointment Scheduling & Booking Calendar WordPress plugin before 1.2.4 does not perform object-level authorisation checks on several of its host-management operations, allowing users who hold its own administrator-assigned custom role to read, modify and permanently delete other hosts' records and the WordPress user accounts linked to them.12hCVE-2026-924214.7 MED3.2%
——1The Hydra Booking — Appointment Scheduling & Booking Calendar WordPress plugin before 1.2.3 does not verify that the host record being modified belongs to the user making the request, allowing authenticated users holding a Hydra Booking — Appointment Scheduling & Booking Calendar WordPress plugin before 1.2.3-assigned host role to modify other hosts' profile data and reassign ownership of another host's record to themselves.12hCVE-2026-924203.8 LOW3.2%
——1The Hydra Booking — Appointment Scheduling & Booking Calendar WordPress plugin before 1.2.2 does not verify that a booking belongs to the requesting user before modifying or deleting it on two of its booking endpoints, allowing a booking-provider-level user to cancel and permanently delete other providers' bookings on the same site.12hCVE-2026-893336.5 MED19.3%
——6The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.0.8 via the 'student_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to disclose the email address and Tutor profile phone number of arbitrary WordPress users, including Administrators, by iterating over user IDs via the student_id parameter.12hCVE-2026-769015.8 MED26.6%
——8CordysCRM is an open source AI-powered customer relationship management system that supports private deployment. Prior to 1.7.4, GET /pool/lead/get/{id} in PoolClueController.get and GET /pool/account/get/{id} in PoolCustomerController.get use bare pool-read permission checks without the CsPermission resourceId binding that enforces per-record data scope. An authenticated user with the ordinary CLUE_MANAGEMENT_POOL:READ or CUSTOMER_MANAGEMENT_POOL:READ permission can supply another record's id and cause unscoped primary-key getters to return leads or accounts owned by other users, departments, or organizations. Exposed data includes contact names, phone numbers, owner and department attribution, and custom field values. This issue is fixed in version 1.7.4.1dCVE-2026-63647—40.2%
——12CordysCRM is an open source AI-powered customer relationship management system that supports private deployment. Prior to 1.7.2, SseController exposes the anonymous /sse/subscribe, /sse/broadcast, and /sse/close endpoints because ShiroFilter.addPublicPathFilters permits the SSE paths, and the endpoints trust the caller-controlled userId instead of deriving an identity from an authenticated principal. An unauthenticated caller can use /sse/subscribe to read another user's workflow events, approval requests, mentions, and alerts, use /sse/broadcast to inject SYSTEM_HEARTBEAT messages into another user's stream, or use /sse/close to terminate another user's channel. This vulnerability is fixed in 1.7.2.1d
