An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-91847 in the wild and no public exploit code.\n\nAffected product: Unknown Online Scheduling and Appointment Booking System. 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-2026-91847/ (Markdown: https://insights.sbomify.com/CVE-2026-91847/index.md)","id":"CVE-2026-91847","markdown":"https://insights.sbomify.com/CVE-2026-91847/index.md","name":"CVE-2026-91847","record":{"aliases":["GHSA-mj5r-8jcf-67xr"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress booking plugin","requires_auth":"none","summary":"Unauthenticated attackers can read and inject messages into other users' AI booking assistant conversations due to missing ownership verification.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The Online Scheduling and Appointment Booking System  WordPress plugin before 28.2 does not verify that the requester owns the AI booking-assistant conversation named in its unauthenticated conversation actions, allowing any unauthenticated visitor to read another visitor's assistant messages and to inject messages into their in-progress conversation.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Bookly \u003c 28.2 - Unauthenticated AI Assistant Conversation Disclosure and Message Injection via IDOR","id":"CVE-2026-91847","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":"WuzhiCMS index.php getDataOfJson sql injection","id":"CVE-2026-91848"},"packages":[],"prev":{"headline":"MISP Collection Element Add Missing Authorization on Referenced Object UUID","id":"CVE-2026-91846"},"products":["Online Scheduling and Appointment Booking System"],"published":"2026-09-19","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-19","vendors":["Unknown"]},"summary":"Unauthenticated attackers can read and inject messages into other users' AI booking assistant conversations due to missing ownership verification.","url":"https://insights.sbomify.com/CVE-2026-91847/"}
