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-2021-20784 in the wild and no public exploit code.\n\nAffected product: voidtools Everything. 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-2021-20784/ (Markdown: https://insights.sbomify.com/CVE-2021-20784/index.md)","id":"CVE-2021-20784","markdown":"https://insights.sbomify.com/CVE-2021-20784/index.md","name":"CVE-2021-20784","record":{"aliases":["GHSA-vxfp-88g2-6m62"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"File search utility","requires_auth":"none","summary":"Remote attackers can inject arbitrary scripts or alter the website via HTTP header injection in the Everything file search utility.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"everything","vendor":"voidtools"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-644","name":"Improper Neutralization of HTTP Headers for Scripting Syntax"}],"description":"HTTP header injection vulnerability in Everything version 1.0, 1.1, and 1.2 except the Lite version may allow a remote attacker to inject an arbitrary script or alter the website that uses the product.","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 Everything","id":"CVE-2021-20784","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in GroupSession","id":"CVE-2021-20785"},"packages":[],"prev":{"headline":"Cross-site request forgery in Optical BB unit E-WMTA2.3","id":"CVE-2021-20783"},"products":["Everything"],"published":"2021-07-14","related":[{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2020-24567","kev_date_added":null,"published":"2020-08-21"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2023-27704","kev_date_added":null,"published":"2023-04-12"}],"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":"2024-12-03","vendors":["voidtools"]},"summary":"Remote attackers can inject arbitrary scripts or alter the website via HTTP header injection in the Everything file search utility.","url":"https://insights.sbomify.com/CVE-2021-20784/"}
