An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-25817 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- silverstripe/framework (Packagist): affected from 4.0.0; fixed in 4.7.4\n- silverstripe/framework (Packagist): affected from 4.0.0; fixed in 4.7.4\n- silverstripe (Bitnami): affected all versions up to 4.6.0-rc1; fixed in 4.6.0\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-2020-25817/ (Markdown: https://insights.sbomify.com/CVE-2020-25817/index.md)","id":"CVE-2020-25817","markdown":"https://insights.sbomify.com/CVE-2020-25817/index.md","name":"CVE-2020-25817","record":{"aliases":["BIT-silverstripe-2020-25817","GHSA-3vjc-5x79-m9r8"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"SilverStripe CMS","requires_auth":"high_privilege","summary":"Misuse of a developer utility for parsing user-submitted data allows XXE attacks, potentially leading to XSS or data exposure in SilverStripe applications.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"silverstripe","vendor":"silverstripe"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"SilverStripe through 4.6.0-rc1 has an XXE Vulnerability in CSSContentParser.
