An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86841 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-2026-86841/ (Markdown: https://insights.sbomify.com/CVE-2026-86841/index.md)","id":"CVE-2026-86841","markdown":"https://insights.sbomify.com/CVE-2026-86841/index.md","name":"CVE-2026-86841","record":{"aliases":["GHSA-ggx5-r53p-pf97"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress booking plugin","requires_auth":"high_privilege","summary":"Privileged users can inject PHP objects to execute code and read secrets in the Bookly WordPress plugin.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.7,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The Online Scheduling and Appointment Booking System  WordPress plugin before 28.3 does not prevent deserialization of untrusted input and does not correctly restrict a privileged maintenance feature to administrators, allowing users granted a custom booking-management capability, which an administrator must explicitly assign, to inject arbitrary PHP objects, overwrite privileged site options, and read stored integration secrets.","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 23.2 - 28.2 - Bookly Administrator+ PHP Object Injection via Diagnostics Advanced Options","id":"CVE-2026-86841","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Real3D Flipbook Lite \u003c 5.4 - Author+ Content Deletion and Stored XSS via Global Settings Overwrite","id":"CVE-2026-86842"},"packages":[],"prev":{"headline":"Bifrost Unauthorized Channel Commission Attribution Allows Commission Diversion","id":"CVE-2026-86840"},"products":["Online Scheduling and Appointment Booking System"],"published":"2026-09-27","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":"2026-09-28","vendors":["Unknown"]},"summary":"Privileged users can inject PHP objects to execute code and read secrets in the Bookly WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-86841/"}
