Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-36955 exists.\n\nAffected product: Getgrav Grav CMS Admin Plugin. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-36955/ (Markdown: https://insights.sbomify.com/CVE-2020-36955/index.md)","id":"CVE-2020-36955","markdown":"https://insights.sbomify.com/CVE-2020-36955/index.md","name":"CVE-2020-36955","record":{"aliases":["GHSA-p5pf-5rc8-g599"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS Admin Plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can inject malicious scripts via page titles in Grav CMS Admin Plugin, leading to code execution or account takeover when viewed.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Grav CMS 1.6.30 with Admin Plugin 1.9.18 contains a persistent cross-site scripting vulnerability that allows authenticated attackers to inject malicious scripts through the page title field.
