An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-11976 exists.\n\nAffected product: Unknown MonsterInsights Pro. 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-2026-11976/ (Markdown: https://insights.sbomify.com/CVE-2026-11976/index.md)","id":"CVE-2026-11976","markdown":"https://insights.sbomify.com/CVE-2026-11976/index.md","name":"CVE-2026-11976","record":{"aliases":["GHSA-w2mq-7hp5-vcv5"],"analysis":{"component_type":"cms_plugin","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers compromised the official update distribution bucket to inject malicious code into MonsterInsights Pro, enabling remote code execution on affected sites.","user_interaction":"not_required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-912","name":"Hidden Functionality"}],"description":"The official MonsterInsights Pro update distribution bucket (`monster-insights.s3.amazonaws.com`) was compromised.
