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-2021-3683 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- showdoc/showdoc (Packagist): affected all versions up to 2.9.12; no fix listed\n- showdoc/showdoc (Packagist): affected all versions up to 2.9.12; no fix listed\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-2021-3683/ (Markdown: https://insights.sbomify.com/CVE-2021-3683/index.md)","id":"CVE-2021-3683","markdown":"https://insights.sbomify.com/CVE-2021-3683/index.md","name":"CVE-2021-3683","record":{"aliases":["GHSA-x5jp-9fmm-m9pf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"ShowDoc documentation tool","requires_auth":"none","summary":"Attackers can trick authenticated users into performing unintended actions in ShowDoc, potentially modifying data or taking over accounts.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"showdoc","vendor":"showdoc"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"showdoc is vulnerable to Cross-Site Request Forgery (CSRF)","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Cross-Site Request Forgery (CSRF) in star7th/showdoc","id":"CVE-2021-3683","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"OpenShift Assisted Installer leaks image pull secrets as plaintext in installation logs","id":"CVE-2021-3684"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["2.9.12"],"package":"showdoc/showdoc","purl":null,"source":"GHSA-x5jp-9fmm-m9pf"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["2.9.12"],"package":"showdoc/showdoc","purl":"pkg:composer/showdoc/showdoc","source":"GHSA-x5jp-9fmm-m9pf"}],"prev":{"headline":"Use after free in QEMU","id":"CVE-2021-3682"},"products":["star7th/showdoc"],"published":"2021-11-13","related":[{"cvss_score":9.8,"headline":"Showdoc File Upload Vulnerability","id":"CVE-2021-41745","kev_date_added":null,"published":"2021-10-22"},{"cvss_score":9.8,"headline":"Unrestricted File Upload in ShowDoc v2.9.5","id":"CVE-2021-36440","kev_date_added":null,"published":"2021-09-08"},{"cvss_score":9.4,"headline":"Stored XSS due to Unrestricted File Upload in star7th/showdoc","id":"CVE-2022-0942","kev_date_added":null,"published":"2022-03-15"},{"cvss_score":9.1,"headline":"There is a Unrestricted Upload of File vulnerability in ShowDoc v2.10.3 in star7th/showdoc","id":"CVE-2022-1034","kev_date_added":null,"published":"2022-03-22"},{"cvss_score":9,"headline":"Stored XSS viva axd and cshtml file upload in star7th/showdoc in star7th/showdoc","id":"CVE-2022-0945","kev_date_added":null,"published":"2022-03-15"},{"cvss_score":9,"headline":"Stored XSS viva .ofd file upload in star7th/showdoc","id":"CVE-2022-0965","kev_date_added":null,"published":"2022-03-15"},{"cvss_score":9,"headline":"Stored XSS viva cshtm file upload in star7th/showdoc","id":"CVE-2022-0946","kev_date_added":null,"published":"2022-03-14"}],"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":"2024-08-03","vendors":["star7th"]},"summary":"Attackers can trick authenticated users into performing unintended actions in ShowDoc, potentially modifying data or taking over accounts.","url":"https://insights.sbomify.com/CVE-2021-3683/"}
