An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-24498 exists.\n\nAffected product: Unknown Calendar Event Multi View. 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-2021-24498/ (Markdown: https://insights.sbomify.com/CVE-2021-24498/index.md)","id":"CVE-2021-24498","markdown":"https://insights.sbomify.com/CVE-2021-24498/index.md","name":"CVE-2021-24498","record":{"aliases":["GHSA-556c-5rxg-4747"],"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 scripts via reflected XSS in the Calendar Event Multi View WordPress plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"calendar_event_multi_view","vendor":"dwbooster"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Calendar Event Multi View WordPress plugin before 1.4.01 does not sanitise or escape the 'start' and 'end' GET parameters before outputting them in the page (via php/edit.php), leading to a reflected Cross-Site Scripting issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-24498.yaml","stars":null,"title":"WordPress Calendar Event Multi View \u003c1.4.01 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Calendar Event Multi View \u003c 1.4.01 - Unauthenticated Reflected Cross-Site Scripting (XSS)","id":"CVE-2021-24498","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Workreap theme \u003c 2.2.2 - Unauthenticated Upload Leading to Remote Code Execution","id":"CVE-2021-24499"},"packages":[],"prev":{"headline":"Giveaway \u003c= 1.2.2 - Authenticated SQL Injection","id":"CVE-2021-24497"},"products":["Calendar Event Multi View"],"published":"2021-08-02","related":[{"cvss_score":4.3,"headline":"Calendar Event Multi View \u003c 1.4.07 - Unauthenticated Arbitrary Event Creation to Stored XSS","id":"CVE-2022-2846","kev_date_added":null,"published":"2022-08-16"}],"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":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Unauthenticated attackers can execute arbitrary scripts via reflected XSS in the Calendar Event Multi View WordPress plugin.","url":"https://insights.sbomify.com/CVE-2021-24498/"}
