An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-24276 and fix it if it is affected.\n\nWhat it is: CVE-2021-24276 is a medium-severity cross-site scripting vulnerability in Contact Form by Supsystic, published on 5 May 2021. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-24276 exists.\n\nAffected product: Contact Form by Supsystic. 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-2021-24276/ (Markdown: https://insights.sbomify.com/CVE-2021-24276/index.md)","id":"CVE-2021-24276","markdown":"https://insights.sbomify.com/CVE-2021-24276/index.md","name":"CVE-2021-24276","record":{"aliases":["GHSA-p8j5-xg8p-f3xm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in the context of other users via the unsanitized tab parameter in the Contact Form by Supsystic plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"contact_form","vendor":"supsystic"}],"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 Contact Form by Supsystic WordPress plugin before 1.7.15 did not sanitise the tab parameter of its options page before outputting it in an attribute, leading to a reflected Cross-Site Scripting issue","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2021-09-28","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":"2021-09-28","kind":"exploitdb","ref":"50344","stars":null,"title":"WordPress Plugin Contact Form 1.7.14 - Reflected Cross-Site Scripting (XSS)"},{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-24276.yaml","stars":null,"title":"WordPress Supsystic Contact Form \u003c1.7.15 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Contact Form by Supsystic \u003c 1.7.15 - Reflected Cross-Site scripting (XSS)","id":"CVE-2021-24276","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"RSS for Yandex Turbo \u003c 1.30 - Authenticated Stored Cross-Site Scripting (XSS)","id":"CVE-2021-24277"},"packages":[],"prev":{"headline":"Popup by Supsystic \u003c 1.10.5 - Reflected Cross-Site scripting (XSS)","id":"CVE-2021-24275"},"products":["Contact Form by Supsystic"],"published":"2021-05-05","related":[{"cvss_score":5.4,"headline":"WordPress Contact Form by Supsystic Plugin \u003c= 1.7.27 is vulnerable to Cross Site Request Forgery (CSRF)","id":"CVE-2023-45068","kev_date_added":null,"published":"2023-10-12"},{"cvss_score":5.4,"headline":"Contact Form by Supsystic \u003c= 1.7.24 - Cross-Site Request Forgery via AJAX action","id":"CVE-2023-2528","kev_date_added":null,"published":"2023-05-16"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Supsystic"]},"summary":"Attackers can execute arbitrary scripts in the context of other users via the unsanitized tab parameter in the Contact Form by Supsystic plugin.","url":"https://insights.sbomify.com/CVE-2021-24276/"}
