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-2020-25631 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- moodle/moodle (Packagist): affected from 3.7; fixed in 3.7.8\n- moodle/moodle (Packagist): affected from 3.7; fixed in 3.7.8\n- moodle/moodle (Packagist): affected from 3.8; fixed in 3.8.5\n- moodle/moodle (Packagist): affected from 3.8; fixed in 3.8.5\n- moodle/moodle (Packagist): affected from 3.9; fixed in 3.9.2\n- moodle/moodle (Packagist): affected from 3.9; fixed in 3.9.2\n- moodle (Bitnami): affected from 3.7.0; fixed in 3.7.8, 3.8.5, 3.9.2\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-2020-25631/ (Markdown: https://insights.sbomify.com/CVE-2020-25631/index.md)","id":"CVE-2020-25631","markdown":"https://insights.sbomify.com/CVE-2020-25631/index.md","name":"CVE-2020-25631","record":{"aliases":["BIT-moodle-2020-25631","GHSA-4w4j-9533-82qg","UBUNTU-CVE-2020-25631"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Moodle LMS","requires_auth":"none","summary":"An attacker can inject JavaScript into book chapter titles in Moodle, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"moodle","vendor":"moodle"}],"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":"A vulnerability was found in Moodle 3.9 to 3.9.1, 3.8 to 3.8.4 and 3.7 to 3.7.7 where it was possible to include JavaScript in a book's chapter title, which was not escaped on the \"Add new chapter\" page.
