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-2021-20746 in the wild and no public exploit code.\n\nAffected product: Hector Cabrera WordPress Popular Posts. 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-2021-20746/ (Markdown: https://insights.sbomify.com/CVE-2021-20746/index.md)","id":"CVE-2021-20746","markdown":"https://insights.sbomify.com/CVE-2021-20746/index.md","name":"CVE-2021-20746","record":{"aliases":["GHSA-pmfx-m292-fc24"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"A remote authenticated attacker can inject arbitrary scripts into WordPress Popular Posts, potentially compromising user sessions or site integrity.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"wordpress_popular_posts","vendor":"wordpress_popular_posts_project"}],"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 WordPress Popular Posts 5.3.2 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":false,"headline":"Cross-site scripting in WordPress Popular Posts","id":"CVE-2021-20746","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Missing authorization in Retty App","id":"CVE-2021-20747"},"packages":[],"prev":{"headline":"Command injection in Inkdrop","id":"CVE-2021-20745"},"products":["WordPress Popular Posts"],"published":"2021-06-28","related":[{"cvss_score":8.8,"headline":"WordPress Popular Posts \u003c= 5.3.2 Authenticated Arbitrary File Upload","id":"CVE-2021-42362","kev_date_added":null,"published":"2021-11-17"},{"cvss_score":7.5,"headline":"Business logic in WordPress Popular Posts","id":"CVE-2022-43468","kev_date_added":null,"published":"2022-12-07"},{"cvss_score":6.5,"headline":"WordPress WordPress Popular Posts Plugin \u003c= 6.3.2 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-45607","kev_date_added":null,"published":"2023-10-18"},{"cvss_score":5.5,"headline":"WordPress Popular Posts plugin \u003c= 5.3.3 - Authenticated Persistent Cross-Site Scripting (XSS) vulnerability","id":"CVE-2021-36872","kev_date_added":null,"published":"2021-09-23"}],"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":["Hector Cabrera"]},"summary":"A remote authenticated attacker can inject arbitrary scripts into WordPress Popular Posts, potentially compromising user sessions or site integrity.","url":"https://insights.sbomify.com/CVE-2021-20746/"}
