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-2021-24812 in the wild and no public exploit code.\n\nAffected product: Unknown BetterLinks – Shorten, Track and Manage any URL. 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-2021-24812/ (Markdown: https://insights.sbomify.com/CVE-2021-24812/index.md)","id":"CVE-2021-24812","markdown":"https://insights.sbomify.com/CVE-2021-24812/index.md","name":"CVE-2021-24812","record":{"aliases":["GHSA-4w3h-ggjg-2hvj"],"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":"low_privilege","summary":"An admin importing a malicious CSV can trigger stored XSS, allowing attackers to execute scripts in the admin interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"betterlinks","vendor":"wpdeveloper"}],"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":"The BetterLinks WordPress plugin before 1.2.6 does not sanitise and escape some of imported link fields, which could lead to Stored Cross-Site Scripting issues when an admin import a malicious CSV.","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":"BetterLinks \u003c 1.2.6 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24812","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Events Made Easy \u003c 2.2.24 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24813"},"packages":[],"prev":{"headline":"Shop Page WP \u003c 1.2.8 - Admin+ Stored Cross-Site Scripting","id":"CVE-2021-24811"},"products":["BetterLinks – Shorten, Track and Manage any URL"],"published":"2021-11-23","related":[{"cvss_score":7.6,"headline":"WordPress BetterLinks plugin \u003c= 2.1.7 - SQL Injection vulnerability","id":"CVE-2024-51672","kev_date_added":null,"published":"2024-11-04"},{"cvss_score":7.3,"headline":"WordPress BetterLinks plugin \u003c= 1.6.0 - Broken Access Control vulnerability","id":"CVE-2023-45104","kev_date_added":null,"published":"2025-01-02"}],"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":"An admin importing a malicious CSV can trigger stored XSS, allowing attackers to execute scripts in the admin interface.","url":"https://insights.sbomify.com/CVE-2021-24812/"}
