An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88853 in the wild and no public exploit code.\n\nAffected product: regularlabs.com Modals (Pro) 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-2026-88853/ (Markdown: https://insights.sbomify.com/CVE-2026-88853/index.md)","id":"CVE-2026-88853","markdown":"https://insights.sbomify.com/CVE-2026-88853/index.md","name":"CVE-2026-88853","record":{"aliases":["GHSA-xc7p-wr44-hv2x"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Modals Pro extension","requires_auth":"high_privilege","summary":"A lower-privileged author can inject malicious JavaScript via event handler options, leading to stored XSS and potential privilege escalation.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N/S:N/AU:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Joomla Extension - regularlabs.com - Privileged stored XSS via event handler option in Modals Pro extension for Joomla \u003c 17.0.0 - Modals Pro intentionally supports JavaScript Events such as on-open and on-closed.
