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-2026-39878 in the wild and no public exploit code.\n\nAffected product: chamilo-lms. 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-2026-39878/ (Markdown: https://insights.sbomify.com/CVE-2026-39878/index.md)","id":"CVE-2026-39878","markdown":"https://insights.sbomify.com/CVE-2026-39878/index.md","name":"CVE-2026-39878","record":{"aliases":["GHSA-gcjp-f7jm-rrrg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Chamilo LMS","requires_auth":"none","summary":"Unauthenticated attackers can inject scripts via registration to hijack admin sessions in Chamilo LMS, requiring an upgrade to secure the platform.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Chamilo LMS versions 1.11.38 and earlier contain a stored cross-site scripting vulnerability in the user registration form that allows any unauthenticated attacker to execute arbitrary JavaScript in an administrator's browser session, leading to full platform admin account takeover.
