An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-3891 exists.\n\nAffected product: Unknown WP FullCalendar. 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-2022-3891/ (Markdown: https://insights.sbomify.com/CVE-2022-3891/index.md)","id":"CVE-2022-3891","markdown":"https://insights.sbomify.com/CVE-2022-3891/index.md","name":"CVE-2022-3891","record":{"aliases":["GHSA-ghxw-rgqv-5cp6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can access content of arbitrary posts, including drafts and private ones, via an AJAX action in the WP FullCalendar plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"wp_fullcalendar","vendor":"pixelite"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[],"description":"The WP FullCalendar WordPress plugin before 1.5 does not ensure that the post retrieved via an AJAX action is public and can be accessed by the user making the request, allowing unauthenticated attackers to get the content of arbitrary posts, including draft/private as well as password-protected ones.","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":"WP FullCalendar \u003c 1.5 - Unauthenticated Arbitrary Post Access","id":"CVE-2022-3891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"WP OAuth Server \u003c 4.2.2 - Admin+ Stored XSS","id":"CVE-2022-3892"},"packages":[],"prev":{"headline":"Memory corruption in Chrome","id":"CVE-2022-3890"},"products":["WP FullCalendar"],"published":"2023-02-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-21","vendors":["Unknown"]},"summary":"Unauthenticated attackers can access content of arbitrary posts, including drafts and private ones, via an AJAX action in the WP FullCalendar plugin.","url":"https://insights.sbomify.com/CVE-2022-3891/"}
