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-2026-84740 in the wild and no public exploit code.\n\nAffected product: Unknown The Events 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-2026-84740/ (Markdown: https://insights.sbomify.com/CVE-2026-84740/index.md)","id":"CVE-2026-84740","markdown":"https://insights.sbomify.com/CVE-2026-84740/index.md","name":"CVE-2026-84740","record":{"aliases":["GHSA-4c37-j68q-cmxj"],"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 execute arbitrary shortcodes in The Events Calendar plugin by manipulating the view_data parameter, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"The Events Calendar WordPress plugin before 6.17.5.1 does not validate or sanitise data submitted to an unauthenticated AJAX action before merging it into its rendering context, allowing unauthenticated users to execute arbitrary shortcodes registered on the site.","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":"The Events Calendar 6.12.0 - 6.17.5 - Unauthenticated Arbitrary Shortcode Execution via 'view_data' Parameter","id":"CVE-2026-84740","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"The Events Calendar 4.5 - 6.17.4.1 - Unauthenticated Non-Public Venue and Organizer Disclosure via REST API","id":"CVE-2026-84741"},"packages":[],"prev":{"headline":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in GitLab","id":"CVE-2026-84739"},"products":["The Events Calendar"],"published":"2026-10-02","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-02","vendors":["Unknown"]},"summary":"Unauthenticated attackers can execute arbitrary shortcodes in The Events Calendar plugin by manipulating the view_data parameter, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2026-84740/"}
