This is due to two compounding weaknesses: (1) a non-user-bound `public_nonce` is exposed to unauthenticated users through the public `/wp-json/ssa/v1/embed-inner` REST endpoint, and (2) the `get_item()` method in `SSA_Settings_Api` relies on `nonce_permissions_check()` for authorization (which accepts the public nonce) but does not call `remove_unauthorized_settings_for_current_user()` to filter restricted fields. This makes it possible for unauthenticated attackers to access admin-only plugin settings including the administrator email, phone number, internal access tokens, notification configurations, and developer settings via the `/wp-json/ssa/v1/settings/{section}` endpoint. The exposure of appointment tokens also allows an attacker to modify or cancel appointments." } ], "title": "Appointment Booking Calendar <= 1.6.9.29 - Missing Authorization to Unauthenticated Sensitive Information Exposure via Settings REST API Endpoint", "references": [ { "url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/5970b8d6-0041-4c30-a6ce-fe67ebf415f5?source=cve" }, { "url": "https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/class-settings-api.php#L128" }, { "url": "https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/lib/td-util/class-td-api-model.php#L361" }, { "url": "https://plugins.trac.wordpress.org/browser/simply-schedule-appointments/tags/1.6.9.21/includes/class-bootstrap.php#L151" }, { "url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3480506%40simply-schedule-appointments%2Ftrunk&old=3475885%40simply-schedule-appointments%2Ftrunk&sfp_email=&sfph_mail=#file0" } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "description": "CWE-862 Missing Authorization", "cweId": "CWE-862", "type": "CWE" } ] } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "baseScore": 7.5, "baseSeverity": "HIGH" } } ], "credits": [ { "lang": "en", "type": "finder", "value": "Muhammad Sharief" } ], "timeline": [ { "time": "2026-02-23T17:48:25.000Z", "lang": "en", "value": "Vendor Notified" }, { "time": "2026-03-12T19:14:03.000Z", "lang": "en", "value": "Disclosed" } ] }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-03-13T16:06:51.327965Z", "id": "CVE-2026-3045", "options": [ { "Exploitation": "none" }, { "Automatable": "yes" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-03-13T16:06:57.240Z" } } ] } }
