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-2022-4320 exists.\n\nAffected product: Unknown WordPress Events Calendar 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-2022-4320/ (Markdown: https://insights.sbomify.com/CVE-2022-4320/index.md)","id":"CVE-2022-4320","markdown":"https://insights.sbomify.com/CVE-2022-4320/index.md","name":"CVE-2022-4320","record":{"aliases":["GHSA-7r7m-9r2x-mccm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress Events Calendar Plugin","requires_auth":"none","summary":"Reflected XSS in WordPress Events Calendar plugin allows attackers to execute scripts against users, including admins, via unsanitized parameters.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"wordpress_events_calendar_plugin","vendor":"mhsoftware"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The WordPress Events Calendar WordPress plugin before 1.4.5 does not sanitize and escapes a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against both unauthenticated and authenticated users (such as high-privilege ones like admin).","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/2022/CVE-2022-4320.yaml","stars":null,"title":"WordPress Events Calendar \u003c1.4.5 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"WordPress Events Calendar Plugin \u003c 1.4.5 - Multiple Reflected XSS","id":"CVE-2022-4320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"PDF Generator for WordPress \u003c 1.1.2 - Reflected XSS","id":"CVE-2022-4321"},"packages":[],"prev":{"headline":"Cri-o: /etc/passwd tampering privesc","id":"CVE-2022-4318"},"products":["WordPress Events Calendar Plugin"],"published":"2023-01-16","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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-04","vendors":["Unknown"]},"summary":"Reflected XSS in WordPress Events Calendar plugin allows attackers to execute scripts against users, including admins, via unsanitized parameters.","url":"https://insights.sbomify.com/CVE-2022-4320/"}
