An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-38337 in the wild and no public exploit code.\n\nAffected product: RSVPMaker Excel. 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-2021-38337/ (Markdown: https://insights.sbomify.com/CVE-2021-38337/index.md)","id":"CVE-2021-38337","markdown":"https://insights.sbomify.com/CVE-2021-38337/index.md","name":"CVE-2021-38337","record":{"aliases":["GHSA-m4ch-hx25-qfhf"],"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":"Attackers can inject arbitrary web scripts via reflected XSS in the RSVPMaker Excel WordPress plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"rsvpmaker_excel","vendor":"carrcommunications"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","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 RSVPMaker Excel WordPress plugin is vulnerable to Reflected Cross-Site Scripting due to a reflected $_SERVER[\"PHP_SELF\"] value in the ~/phpexcel/PHPExcel/Shared/JAMA/docs/download.php file which allows attackers to inject arbitrary web scripts, in versions up to and including 1.1.","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":"RSVPMaker Excel \u003c= 1.1 Reflected Cross-Site Scripting","id":"CVE-2021-38337","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Border Loading Bar \u003c= 1.0.1 Reflected Cross-Site Scripting","id":"CVE-2021-38338"},"packages":[],"prev":{"headline":"Edit Comments XT \u003c= 1.0 Reflected Cross-Site Scripting","id":"CVE-2021-38336"},"products":["RSVPMaker Excel"],"published":"2021-09-10","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-02","vendors":["RSVPMaker Excel"]},"summary":"Attackers can inject arbitrary web scripts via reflected XSS in the RSVPMaker Excel WordPress plugin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-38337/"}
