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-2021-25091 in the wild and no public exploit code.\n\nAffected product: Unknown Link Library. 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-2021-25091/ (Markdown: https://insights.sbomify.com/CVE-2021-25091/index.md)","id":"CVE-2021-25091","markdown":"https://insights.sbomify.com/CVE-2021-25091/index.md","name":"CVE-2021-25091","record":{"aliases":["GHSA-76j9-mfwr-cgfp"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Reflected XSS in Link Library plugin allows attackers to execute scripts in admin pages via unsanitized input.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"link_library","vendor":"ylefebvre"}],"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":"The Link Library WordPress plugin before 7.2.9 does not sanitise and escape the settingscopy parameter before outputting it back in an admin page, leading to a Reflected Cross-Site Scripting","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":"Link Library \u003c 7.2.9 - Reflected Cross-Site Scripting","id":"CVE-2021-25091","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Link Library \u003c 7.2.8 - Library Settings Reset via CSRF","id":"CVE-2021-25092"},"packages":[],"prev":{"headline":"GridKit Portfolio \u003c 2.1.0 - Subscriber+ Stored Cross-Site Scripting","id":"CVE-2021-25090"},"products":["Link Library"],"published":"2022-02-01","related":[{"cvss_score":7.5,"headline":"Link Library \u003c 7.2.8 - Unauthenticated Arbitrary Links Deletion","id":"CVE-2021-25093","kev_date_added":null,"published":"2022-02-01"},{"cvss_score":7.1,"headline":"WordPress Link Library plugin \u003c= 7.7.1 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2024-38711","kev_date_added":null,"published":"2024-07-20"},{"cvss_score":7.1,"headline":"WordPress Link Library plugin \u003c= 7.6.3 - Reflected Cross-Site Scripting (XSS) vulnerability","id":"CVE-2024-35687","kev_date_added":null,"published":"2024-06-08"},{"cvss_score":7.1,"headline":"WordPress Link Library plugin \u003c= 7.6 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2024-29123","kev_date_added":null,"published":"2024-03-19"},{"cvss_score":7.1,"headline":"WordPress Link Library Plugin \u003c= 7.5.13 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2024-24879","kev_date_added":null,"published":"2024-02-08"},{"cvss_score":6.5,"headline":"WordPress Link Library plugin \u003c= 7.8 - Cross Site Scripting (XSS) Vulnerability","id":"CVE-2025-46237","kev_date_added":null,"published":"2025-04-22"},{"cvss_score":6.5,"headline":"Link Library \u003c= 7.6 - Unauthenticated Stored Cross-Site Scripting","id":"CVE-2024-1559","kev_date_added":null,"published":"2024-02-20"}],"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":["Unknown"]},"summary":"Reflected XSS in Link Library plugin allows attackers to execute scripts in admin pages via unsanitized input.","url":"https://insights.sbomify.com/CVE-2021-25091/"}
