Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-65891 and fix it if it is affected.\n\nWhat it is: CVE-2026-65891 is a medium-severity path traversal vulnerability in joomlacontenteditor.net Joomla Content Editor (JCE) extension for Joomla, published on 29 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-65891 in the wild and no public exploit code.\n\nAffected product: joomlacontenteditor.net Joomla Content Editor (JCE) extension for Joomla. 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-2026-65891/ (Markdown: https://insights.sbomify.com/CVE-2026-65891/index.md)","id":"CVE-2026-65891","markdown":"https://insights.sbomify.com/CVE-2026-65891/index.md","name":"CVE-2026-65891","record":{"aliases":["GHSA-chfv-whhw-v522"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Content Editor","requires_auth":"low_privilege","summary":"Authenticated users can rename files to hidden names or overwrite existing files due to improper input validation in the JCE extension.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[{"product":"jce","vendor":"widgetfactorylimited"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Joomla Extension - joomlacontenteditor.net - Creation of hidden files and unintended file overwrite via rename function in Joomla Content Editor (JCE) \u003c 2.20.2 - Improper input validation in the file rename functionality allowed an authenticated user with file management permissions to rename files to otherwise invalid names, resulting in the creation of hidden files.
