Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16541 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-2026-16541/ (Markdown: https://insights.sbomify.com/CVE-2026-16541/index.md)","id":"CVE-2026-16541","markdown":"https://insights.sbomify.com/CVE-2026-16541/index.md","name":"CVE-2026-16541","record":{"aliases":["GHSA-9337-jrpr-pg7c"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Low-privileged staff users can access REST endpoints to disclose names and email addresses of arbitrary registered users in the Simply Schedule Appointments plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Simply Schedule Appointments WordPress plugin before 1.6.12.17 does not restrict the user records returned by some of its REST endpoints to those the requester is entitled to see, allowing users with a low-privileged staff role to disclose the names and email addresses of arbitrary registered users.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Simply Schedule Appointments \u003c 1.6.12.17 - Team Member+ User Email Disclosure via Users and Customers REST Endpoints","id":"CVE-2026-16541","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":"Import and export users and customers \u003c 2.4.5 - Admin+ SSRF via bp_avatar","id":"CVE-2026-16542"},"packages":[],"prev":{"headline":"Missing authorization in Simply Schedule Appointments","id":"CVE-2026-16540"},"products":["Simply Schedule Appointments"],"published":"2026-08-15","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)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-17","vendors":["Unknown"]},"summary":"Low-privileged staff users can access REST endpoints to disclose names and email addresses of arbitrary registered users in the Simply Schedule Appointments plugin.","url":"https://insights.sbomify.com/CVE-2026-16541/"}
