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-2021-3989 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- showdoc/showdoc (Packagist): affected all versions; fixed in 2.9.13\n- showdoc/showdoc (Packagist): affected all versions; fixed in 2.9.13\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-2021-3989/ (Markdown: https://insights.sbomify.com/CVE-2021-3989/index.md)","id":"CVE-2021-3989","markdown":"https://insights.sbomify.com/CVE-2021-3989/index.md","name":"CVE-2021-3989","record":{"aliases":["GHSA-f545-vpwp-r9j7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ShowDoc documentation tool","requires_auth":"none","summary":"An attacker can redirect users to malicious sites via ShowDoc, potentially facilitating phishing attacks.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"showdoc","vendor":"showdoc"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"showdoc is vulnerable to URL Redirection to Untrusted Site","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":true,"headline":"Open Redirect in star7th/showdoc","id":"CVE-2021-3989","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"open_redirect","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in star7th/showdoc","id":"CVE-2021-3990"},"packages":[{"ecosystem":"Packagist","fixed":["2.9.13"],"introduced":["0"],"last_affected":[],"package":"showdoc/showdoc","purl":null,"source":"GHSA-f545-vpwp-r9j7"},{"ecosystem":"Packagist","fixed":["2.9.13"],"introduced":["0"],"last_affected":[],"package":"showdoc/showdoc","purl":"pkg:composer/showdoc/showdoc","source":"GHSA-f545-vpwp-r9j7"}],"prev":{"headline":"Cross-site Scripting (XSS) in janeczku/calibre-web","id":"CVE-2021-3988"},"products":["star7th/showdoc"],"published":"2021-12-01","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":"An attacker can redirect users to malicious sites via ShowDoc, potentially facilitating phishing attacks.","url":"https://insights.sbomify.com/CVE-2021-3989/"}
