An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100751 in the wild and no public exploit code.\n\nAffected product: regularlabs.com Tabs \u0026 Accordions (Free, 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-2026-100751/ (Markdown: https://insights.sbomify.com/CVE-2026-100751/index.md)","id":"CVE-2026-100751","markdown":"https://insights.sbomify.com/CVE-2026-100751/index.md","name":"CVE-2026-100751","record":{"aliases":["GHSA-cmhf-vxj4-v56x"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla extension","requires_auth":"high_privilege","summary":"Privileged users can inject JavaScript via URL attributes in Tabs \u0026 Accordions, leading to stored XSS and potential account takeover.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[{"product":"tabs_\\\u0026_accordions","vendor":"regularlabs"}],"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 data-rlta-url attributes in Tabs \u0026 Accordions (Pro) 2.3.0 - 3.1.0 - Tabs \u0026 Accordions Pro accepts a url option for an item and writes it to a generated data-rlta-url attribute.
