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-2021-23648 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @braintree/sanitize-url (npm): affected all versions; fixed in 6.0.0\n- @braintree/sanitize-url (npm): affected all versions; fixed in 6.0.0\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-2021-23648/ (Markdown: https://insights.sbomify.com/CVE-2021-23648/index.md)","id":"CVE-2021-23648","markdown":"https://insights.sbomify.com/CVE-2021-23648/index.md","name":"CVE-2021-23648","record":{"aliases":["DEBIAN-CVE-2021-23648","GHSA-hqq7-2q2v-82xq","SNYK-JS-BRAINTREESANITIZEURL-2339882","UBUNTU-CVE-2021-23648"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript URL sanitizer","requires_auth":"none","summary":"An attacker can execute arbitrary scripts via improper URL sanitization in the @braintree/sanitize-url library, affecting applications using this package.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"braintree\\/sanitize-url","vendor":"paypal"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:P","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The package @braintree/sanitize-url before 6.0.0 are vulnerable to Cross-site Scripting (XSS) due to improper sanitization in sanitizeUrl function.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Cross-site Scripting (XSS)","id":"CVE-2021-23648","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"xss","year":"2021"},"n_packages":2,"n_references":7,"next":{"headline":"Improper Input Validation","id":"CVE-2021-23654"},"packages":[{"ecosystem":"npm","fixed":["6.0.0"],"introduced":["0"],"last_affected":[],"package":"@braintree/sanitize-url","purl":null,"source":"GHSA-hqq7-2q2v-82xq"},{"ecosystem":"npm","fixed":["6.0.0"],"introduced":["0"],"last_affected":[],"package":"@braintree/sanitize-url","purl":"pkg:npm/%40braintree/sanitize-url","source":"GHSA-hqq7-2q2v-82xq"}],"prev":{"headline":"Remote Code Execution (RCE)","id":"CVE-2021-23639"},"products":["@braintree/sanitize-url"],"published":"2022-03-16","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-09-16","vendors":["n/a"]},"summary":"An attacker can execute arbitrary scripts via improper URL sanitization in the @braintree/sanitize-url library, affecting applications using this package.","url":"https://insights.sbomify.com/CVE-2021-23648/"}
