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-2026-12378 in the wild and no public exploit code.\n\nAffected product: Unknown Appointment Booking Calendar Plugin and Scheduling Plugin. 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-2026-12378/ (Markdown: https://insights.sbomify.com/CVE-2026-12378/index.md)","id":"CVE-2026-12378","markdown":"https://insights.sbomify.com/CVE-2026-12378/index.md","name":"CVE-2026-12378","record":{"aliases":["GHSA-5jfm-f958-c6pr"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject PHP objects to achieve remote code execution if a suitable gadget chain exists.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The Appointment Booking Calendar Plugin and Scheduling Plugin  WordPress plugin through 1.1.28 does not validate data before passing it to a PHP deserialization function, allowing unauthenticated attackers to inject arbitrary PHP objects; where a suitable gadget chain is present on the site this can be leveraged to achieve remote code execution.","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":"BookingPress \u003c= 1.1.28 - Unauthenticated PHP Object Injection","id":"CVE-2026-12378","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Dashboard OAuth/OIDC implementation of Axivion","id":"CVE-2026-12379"},"packages":[],"prev":{"headline":"Academy LMS \u003c= 3.8.2 - Subscriber+ Sensitive Information Disclosure via quiz_attempts REST Endpoint","id":"CVE-2026-12376"},"products":["Appointment Booking Calendar Plugin and Scheduling Plugin"],"published":"2026-07-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-08","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject PHP objects to achieve remote code execution if a suitable gadget chain exists.","url":"https://insights.sbomify.com/CVE-2026-12378/"}
