An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16540 exists.\n\nAffected product: Unknown Simply Schedule Appointments. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-16540/ (Markdown: https://insights.sbomify.com/CVE-2026-16540/index.md)","id":"CVE-2026-16540","markdown":"https://insights.sbomify.com/CVE-2026-16540/index.md","name":"CVE-2026-16540","record":{"aliases":["GHSA-j5pv-734r-xv95"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can access all appointment data and delete appointments due to missing authorization checks in the purge endpoint.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"The Simply Schedule Appointments WordPress plugin before 1.6.12.6 does not correctly restrict a bulk appointment operation to the requester's own records, allowing unauthenticated users to retrieve the personal data of all appointments across the site and, on premium editions, to permanently delete them.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-07-22","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-07-22T15:15:53Z","kind":"github_poc","ref":"https://github.com/huseyn0vs/CVE-2026-16540-SimplyScheduleAppointments","stars":1,"title":"CVE-2026-16540 — Simply Schedule Appointments \u003c 1.6.12.6 Unauthenticated Appointment Data Disclosure and Mass Deletion"}],"tier":"weaponised"},"has_fix":null,"headline":"Missing authorization in Simply Schedule Appointments","id":"CVE-2026-16540","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Simply Schedule Appointments \u003c 1.6.12.17 - Team Member+ User Email Disclosure via Users and Customers REST Endpoints","id":"CVE-2026-16541"},"packages":[],"prev":{"headline":"SM Page Duplicator \u003c= 1.0.0 - Editor+ SQL Injection via Page Duplication","id":"CVE-2026-16539"},"products":["Simply Schedule Appointments"],"published":"2026-08-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-03","vendors":["Unknown"]},"summary":"Unauthenticated attackers can access all appointment data and delete appointments due to missing authorization checks in the purge endpoint.","url":"https://insights.sbomify.com/CVE-2026-16540/"}
