Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20749 in the wild and no public exploit code.\n\nAffected product: nendeb 'Fudousan plugin' series. 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-2021-20749/ (Markdown: https://insights.sbomify.com/CVE-2021-20749/index.md)","id":"CVE-2021-20749","markdown":"https://insights.sbomify.com/CVE-2021-20749/index.md","name":"CVE-2021-20749","record":{"aliases":["GHSA-2xw3-pxr3-cr4c"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress real estate plugin","requires_auth":"low_privilege","summary":"Remote authenticated attackers can inject arbitrary scripts into the Fudousan real estate plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"fudousan_plugin","vendor":"nendeb"},{"product":"fudousan_plugin_pro_multi-user","vendor":"nendeb"},{"product":"fudousan_plugin_pro_single-user","vendor":"nendeb"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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 Fudousan plugin ver5.7.0 and earlier, Fudousan Plugin Pro Single-User Type ver5.7.0 and earlier, and Fudousan Plugin Pro Multi-User Type ver5.7.0 and earlier allows a remote authenticated attacker to inject an arbitrary script 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 'Fudousan plugin' series","id":"CVE-2021-20749","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"EC-CUBE Cross-site scripting vulnerability","id":"CVE-2021-20750"},"packages":[],"prev":{"headline":"Hardcoded credentials in Retty App","id":"CVE-2021-20748"},"products":["'Fudousan plugin' series"],"published":"2021-06-28","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["nendeb"]},"summary":"Remote authenticated attackers can inject arbitrary scripts into the Fudousan real estate plugin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-20749/"}
