Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-19626 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- craftcms/cms (Packagist): affected all versions; fixed in 3.1.33\n- craftcms/cms (Packagist): affected all versions; fixed in 3.1.33\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-2020-19626/ (Markdown: https://insights.sbomify.com/CVE-2020-19626/index.md)","id":"CVE-2020-19626","markdown":"https://insights.sbomify.com/CVE-2020-19626/index.md","name":"CVE-2020-19626","record":{"aliases":["GHSA-33jj-92px-m4g7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Craft CMS","requires_auth":"low_privilege","summary":"Remote attackers can inject arbitrary web script or HTML into Craft CMS admin settings, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"craft_cms","vendor":"craftcms"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Cross Site Scripting (XSS) vulnerability in craftcms 3.1.31, allows remote attackers to inject arbitrary web script or HTML, via /admin/settings/sites/new.","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":"Craft CMS Cross-site Scripting Vulnerability","id":"CVE-2020-19626","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"craftcms:craft_cms","products":["craftcms:craft_cms"],"type":"xss","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-19639"},"packages":[{"ecosystem":"Packagist","fixed":["3.1.33"],"introduced":["0"],"last_affected":[],"package":"craftcms/cms","purl":null,"source":"GHSA-33jj-92px-m4g7"},{"ecosystem":"Packagist","fixed":["3.1.33"],"introduced":["0"],"last_affected":[],"package":"craftcms/cms","purl":"pkg:composer/craftcms/cms","source":"GHSA-33jj-92px-m4g7"}],"prev":{"headline":"Code injection in n/a","id":"CVE-2020-19625"},"products":["n/a"],"published":"2021-03-26","related":[{"cvss_score":10,"headline":"Craft CMS Code Injection","id":"CVE-2025-32432","kev_date_added":"2026-03-20","published":"2025-04-25"},{"cvss_score":9.3,"headline":"Craft CMS Code Injection","id":"CVE-2024-56145","kev_date_added":"2025-06-02","published":"2024-12-18"},{"cvss_score":8.1,"headline":"Craft CMS Code Injection","id":"CVE-2025-23209","kev_date_added":"2025-02-20","published":"2025-01-18"},{"cvss_score":6.9,"headline":"Craft CMS External Control of Assumed-Immutable Web Parameter","id":"CVE-2025-35939","kev_date_added":"2025-06-02","published":"2025-05-07"},{"cvss_score":10,"headline":"Craft CMS Remote Code Execution vulnerability","id":"CVE-2023-41892","kev_date_added":null,"published":"2023-09-13"},{"cvss_score":9.8,"headline":"Craft CMS Remote Code Injection","id":"CVE-2021-27903","kev_date_added":null,"published":"2021-06-30"},{"cvss_score":9.8,"headline":"SEOmatic for CraftCMS allows Server-Side Template Injection","id":"CVE-2020-9757","kev_date_added":null,"published":"2020-03-04"}],"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":"Remote attackers can inject arbitrary web script or HTML into Craft CMS admin settings, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2020-19626/"}
