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-2023-31506 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- getgrav/grav (Packagist): affected all versions; no fix listed\n- getgrav/grav (Packagist): affected all versions; 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-2023-31506/ (Markdown: https://insights.sbomify.com/CVE-2023-31506/index.md)","id":"CVE-2023-31506","markdown":"https://insights.sbomify.com/CVE-2023-31506/index.md","name":"CVE-2023-31506","record":{"aliases":["GHSA-xrf8-cmrg-7436"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary scripts via XSS in Grav CMS, potentially compromising user sessions or data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"grav","vendor":"getgrav"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","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":"A cross-site scripting (XSS) vulnerability in Grav versions 1.7.44 and before, allows remote authenticated attackers to execute arbitrary web scripts or HTML via the onmouseover attribute of an ISINDEX element.","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 scripting (XSS) vulnerability in Grav","id":"CVE-2023-31506","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"getgrav:grav","products":["getgrav:grav"],"type":"xss","year":"2023"},"n_packages":2,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2023-31517"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":[],"package":"getgrav/grav","purl":null,"source":"GHSA-xrf8-cmrg-7436"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":[],"package":"getgrav/grav","purl":"pkg:composer/getgrav/grav","source":"GHSA-xrf8-cmrg-7436"}],"prev":{"headline":"File upload in n/a","id":"CVE-2023-31505"},"products":["n/a"],"published":"2024-02-09","related":[{"cvss_score":10,"headline":"Grav Server Side Template Injection vulnerability","id":"CVE-2023-34251","kev_date_added":null,"published":"2023-06-14"},{"cvss_score":9.8,"headline":"Cross-site scripting in n/a","id":"CVE-2025-46199","kev_date_added":null,"published":"2025-07-25"},{"cvss_score":9.3,"headline":"GravCMS 1.10.7 - Arbitrary YAML Write/Update (Unauthenticated) (2)","id":"CVE-2021-47812","kev_date_added":null,"published":"2026-01-15"},{"cvss_score":9.1,"headline":"Grav may be vulnerable to SSRF attack via Twig Templates","id":"CVE-2025-66844","kev_date_added":null,"published":"2025-12-15"},{"cvss_score":9.1,"headline":"Code Injection in getgrav/grav","id":"CVE-2022-2073","kev_date_added":null,"published":"2022-06-29"},{"cvss_score":8.9,"headline":"Grav: Stored XSS via Tag Injection","id":"CVE-2026-42611","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":8.8,"headline":"Grav: Unauthenticated Path Traversal \u0026 Arbitrary File Write in FormFlash component.","id":"CVE-2026-42608","kev_date_added":null,"published":"2026-05-11"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-16","vendors":["n/a"]},"summary":"Authenticated attackers can execute arbitrary scripts via XSS in Grav CMS, potentially compromising user sessions or data.","url":"https://insights.sbomify.com/CVE-2023-31506/"}
