An attacker can exploit it over the internet without logging in, 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-2023-6379 exists.\n\nAffected packages and fixed versions:\n- org.opencms:opencms-core (Maven): affected from 14.0.0; fixed in 16.0.0\n- org.opencms:opencms-core (Maven): affected from 14.0.0; fixed in 16.0.0\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-2023-6379/ (Markdown: https://insights.sbomify.com/CVE-2023-6379/index.md)","id":"CVE-2023-6379","markdown":"https://insights.sbomify.com/CVE-2023-6379/index.md","name":"CVE-2023-6379","record":{"aliases":["GHSA-w62v-q77r-66cc"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenCms CMS","requires_auth":"none","summary":"Remote attackers can inject JavaScript into the Mercury template to hijack user sessions in OpenCms.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[{"product":"opencms","vendor":"alkacon"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site scripting (XSS) vulnerability in Alkacon Software Open CMS, affecting versions 14 and 15 of the 'Mercury' template.
