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-2021-24146 exists.\n\nAffected product: Unknown Modern Events Calendar Lite. 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-2021-24146/ (Markdown: https://insights.sbomify.com/CVE-2021-24146/index.md)","id":"CVE-2021-24146","markdown":"https://insights.sbomify.com/CVE-2021-24146/index.md","name":"CVE-2021-24146","record":{"aliases":["GHSA-2qh8-fp5p-2xx2"],"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 export all event data from the Modern Events Calendar Lite WordPress plugin due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"modern_events_calendar_lite","vendor":"webnus"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Lack of authorisation checks in the Modern Events Calendar Lite WordPress plugin, versions before 5.16.5, did not properly restrict access to the export files, allowing unauthenticated users to exports all events data in CSV or XML format for example.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2021-07-02","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":"2021-07-02","kind":"exploitdb","ref":"50084","stars":null,"title":"Wordpress Plugin Modern Events Calendar 5.16.2 - Event export (Unauthenticated)"},{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-24146.yaml","stars":null,"title":"WordPress Modern Events Calendar Lite \u003c5.16.5 - Sensitive Information Disclosure"}],"tier":"weaponised"},"has_fix":false,"headline":"Modern Events Calendar Lite \u003c 5.16.5 - Unauthenticated Events Export","id":"CVE-2021-24146","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Modern Events Calendar Lite \u003c 5.16.5 - Authenticated Stored Cross-Site Scripting (XSS)","id":"CVE-2021-24147"},"packages":[],"prev":{"headline":"Modern Events Calendar Lite \u003c 5.16.5 - Authenticated Arbitrary File Upload leading to RCE","id":"CVE-2021-24145"},"products":["Modern Events Calendar Lite"],"published":"2021-03-18","related":[{"cvss_score":9.8,"headline":"Modern Events Calendar \u003c 6.1.5 - Unauthenticated Blind SQL Injection","id":"CVE-2021-24946","kev_date_added":null,"published":"2021-12-13"},{"cvss_score":8.8,"headline":"Modern Events Calendar Lite \u003c 5.16.6 - Authenticated SQL Injection","id":"CVE-2021-24149","kev_date_added":null,"published":"2021-03-18"},{"cvss_score":7.2,"headline":"Modern Events Calendar Lite \u003c 5.16.5 - Authenticated Arbitrary File Upload leading to RCE","id":"CVE-2021-24145","kev_date_added":null,"published":"2021-03-18"},{"cvss_score":6.1,"headline":"Modern Events Calendar Lite \u003c 6.1.5 - Reflected Cross-Site Scripting","id":"CVE-2021-24925","kev_date_added":null,"published":"2021-12-13"},{"cvss_score":5.9,"headline":"Modern Events Calendar Lite \u003c= 6.3.0 - Unauthenticated SQL Injection","id":"CVE-2021-4458","kev_date_added":null,"published":"2025-07-12"},{"cvss_score":5.4,"headline":"Cross-site scripting in Modern Events Calendar Lite","id":"CVE-2022-30533","kev_date_added":null,"published":"2022-06-16"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Unauthenticated attackers can export all event data from the Modern Events Calendar Lite WordPress plugin due to missing authorization checks.","url":"https://insights.sbomify.com/CVE-2021-24146/"}
