Welcart e-Commerce, published on 22 Jun 2021. 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-2021-20734 in the wild and no public exploit code.\n\nAffected product: Collne Inc. Welcart e-Commerce. 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-2021-20734/ (Markdown: https://insights.sbomify.com/CVE-2021-20734/index.md)","id":"CVE-2021-20734","markdown":"https://insights.sbomify.com/CVE-2021-20734/index.md","name":"CVE-2021-20734","record":{"aliases":["GHSA-m59w-q74p-9vg2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress e-commerce plugin","requires_auth":"none","summary":"Remote attackers can inject arbitrary scripts into Welcart e-Commerce, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"welcart_e-commerce","vendor":"welcart"}],"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":"Cross-site scripting vulnerability in Welcart e-Commerce versions prior to 2.2.4 allows remote attackers to inject arbitrary script or HTML via unspecified vectors.","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":"Cross-site scripting in Welcart e-Commerce","id":"CVE-2021-20734","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in ETUNA EC-CUBE plugins","id":"CVE-2021-20735"},"packages":[],"prev":{"headline":"Open redirect in あすけんダイエット (asken diet) for Android","id":"CVE-2021-20733"},"products":["Welcart e-Commerce"],"published":"2021-06-22","related":[{"cvss_score":9.8,"headline":"Welcart e-Commerce \u003c 2.9.5 - Unauthenticated PHP Object Injection","id":"CVE-2023-5952","kev_date_added":null,"published":"2023-12-04"},{"cvss_score":8.8,"headline":"SQL injection in Welcart e-Commerce","id":"CVE-2024-42404","kev_date_added":null,"published":"2024-09-18"},{"cvss_score":8.8,"headline":"Welcart e-Commerce \u003c 2.9.5 - Subscriber+ Arbitrary File Upload","id":"CVE-2023-5953","kev_date_added":null,"published":"2023-12-04"},{"cvss_score":8.8,"headline":"SQL injection in Welcart e-Commerce","id":"CVE-2023-43610","kev_date_added":null,"published":"2023-09-26"},{"cvss_score":8.8,"headline":"Welcart e-Commerce \u003c 2.8.6 - Subscriber+ PHAR Deserialisation","id":"CVE-2022-4237","kev_date_added":null,"published":"2023-01-02"},{"cvss_score":7.6,"headline":"WordPress Welcart e-Commerce Plugin \u003c= 2.9.3 is vulnerable to SQL Injection","id":"CVE-2023-50847","kev_date_added":null,"published":"2023-12-28"},{"cvss_score":7.5,"headline":"Welcart e-Commerce \u003c 2.2.8 - Missing Capabilities Check to Information Disclosure","id":"CVE-2021-4355","kev_date_added":null,"published":"2023-06-07"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Collne Inc."]},"summary":"Remote attackers can inject arbitrary scripts into Welcart e-Commerce, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2021-20734/"}
