An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-39926 and fix it if it is affected.\n\nWhat it is: CVE-2023-39926 is a high-severity cross-site scripting vulnerability in Under Construction / Maintenance Mode from Acurax, published on 16 Nov 2023. 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-2023-39926 exists.\n\nAffected product: Under Construction / Maintenance Mode from Acurax. 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-2023-39926/ (Markdown: https://insights.sbomify.com/CVE-2023-39926/index.md)","id":"CVE-2023-39926","markdown":"https://insights.sbomify.com/CVE-2023-39926/index.md","name":"CVE-2023-39926","record":{"aliases":["GHSA-qh33-c8m9-ggwr"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts via stored XSS in the Acurax Under Construction plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"under_construction_\\/_maintenance_mode","vendor":"acurax"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Unauth.
