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-2021-43353 in the wild and no public exploit code.\n\nAffected product: Crisp Live Chat. 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-2021-43353/ (Markdown: https://insights.sbomify.com/CVE-2021-43353/index.md)","id":"CVE-2021-43353","markdown":"https://insights.sbomify.com/CVE-2021-43353/index.md","name":"CVE-2021-43353","record":{"aliases":["GHSA-mrwr-9wqr-6fc2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can exploit missing nonce validation to inject arbitrary scripts via CSRF, potentially leading to stored XSS in the Crisp Live Chat plugin.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"crisp","vendor":"crisp"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"The Crisp Live Chat WordPress plugin is vulnerable to Cross-Site Request Forgery due to missing nonce validation via the crisp_plugin_settings_page function found in the ~/crisp.php file, which made it possible for attackers to inject arbitrary web scripts in versions up to, and including 0.31.","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":"Crisp Live Chat \u003c= 0.31 Cross-Site Request Forgery to Stored Cross-Site Scripting","id":"CVE-2021-43353","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Fresenius Kabi Agilia Connect Infusion System use of client side authentication","id":"CVE-2021-43355"},"packages":[],"prev":{"headline":"This is unused.","id":"CVE-2021-43351"},"products":["Crisp Live Chat"],"published":"2022-01-18","related":[{"cvss_score":6.5,"headline":"WordPress Crisp – Live Chat and Chatbot plugin \u003c= 0.44 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2024-27963","kev_date_added":null,"published":"2024-03-21"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-01-31","vendors":["Crisp Live Chat"]},"summary":"Attackers can exploit missing nonce validation to inject arbitrary scripts via CSRF, potentially leading to stored XSS in the Crisp Live Chat plugin.","url":"https://insights.sbomify.com/CVE-2021-43353/"}
