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-2020-13633 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- forkcms/forkcms (Packagist): affected all versions; fixed in 5.8.3\n- forkcms/forkcms (Packagist): affected all versions; fixed in 5.8.3\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-2020-13633/ (Markdown: https://insights.sbomify.com/CVE-2020-13633/index.md)","id":"CVE-2020-13633","markdown":"https://insights.sbomify.com/CVE-2020-13633/index.md","name":"CVE-2020-13633","record":{"aliases":["GHSA-74gc-hf33-5353"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP Fork library","requires_auth":"none","summary":"Cross-site scripting vulnerability in the Fork library allows attackers to inject malicious scripts via navigation_title or title parameters.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fork_cms","vendor":"fork-cms"}],"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":"Fork before 5.8.3 allows XSS via navigation_title or title.","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":"Fork CMS Cross-site Scripting Vulnerability","id":"CVE-2020-13633","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-13634"},"packages":[{"ecosystem":"Packagist","fixed":["5.8.3"],"introduced":["0"],"last_affected":[],"package":"forkcms/forkcms","purl":null,"source":"GHSA-74gc-hf33-5353"},{"ecosystem":"Packagist","fixed":["5.8.3"],"introduced":["0"],"last_affected":[],"package":"forkcms/forkcms","purl":"pkg:composer/forkcms/forkcms","source":"GHSA-74gc-hf33-5353"}],"prev":{"headline":"Null dereference in n/a","id":"CVE-2020-13632"},"products":["n/a"],"published":"2020-05-27","related":[{"cvss_score":9.8,"headline":"Spoon Library as used in Fork CMS allows PHP object injection","id":"CVE-2019-15521","kev_date_added":null,"published":"2019-08-26"},{"cvss_score":9.6,"headline":"SQL Injection in forkcms/forkcms","id":"CVE-2022-0153","kev_date_added":null,"published":"2022-03-24"},{"cvss_score":9,"headline":"SQL injection through marking blog comments on bulk as spam in forkcms/forkcms","id":"CVE-2022-1064","kev_date_added":null,"published":"2022-03-25"},{"cvss_score":8.8,"headline":"Arbitrary file upload in Fork CMS","id":"CVE-2021-28931","kev_date_added":null,"published":"2021-07-07"},{"cvss_score":8.8,"headline":"Cross-Site Request Forgery in forkcms","id":"CVE-2020-23264","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":8.8,"headline":"Deserialization in n/a","id":"CVE-2020-24036","kev_date_added":null,"published":"2021-03-04"},{"cvss_score":8.8,"headline":"Cross-Site Request Forgery in ForkCMS","id":"CVE-2020-23960","kev_date_added":null,"published":"2021-01-11"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Cross-site scripting vulnerability in the Fork library allows attackers to inject malicious scripts via navigation_title or title parameters.","url":"https://insights.sbomify.com/CVE-2020-13633/"}
