Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-12111 in the wild and no public exploit code.\n\nAffected product: codepeople Appointment Booking Calendar. 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-2026-12111/ (Markdown: https://insights.sbomify.com/CVE-2026-12111/index.md)","id":"CVE-2026-12111","markdown":"https://insights.sbomify.com/CVE-2026-12111/index.md","name":"CVE-2026-12111","record":{"aliases":["GHSA-w9f2-px6f-gvmg"],"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":"Authenticated contributors can access sensitive customer booking data from any calendar due to missing ownership checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Appointment Booking Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 1.4.01.
