An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-3956 in the wild and no public exploit code.\n\nAffected product: InstaWP Connect – 1-click WP Staging \u0026 Migration. 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-2023-3956/ (Markdown: https://insights.sbomify.com/CVE-2023-3956/index.md)","id":"CVE-2023-3956","markdown":"https://insights.sbomify.com/CVE-2023-3956/index.md","name":"CVE-2023-3956","record":{"aliases":["GHSA-84qr-g4jc-2m5f"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can modify posts, users, and plugins, or install plugins due to missing capability checks in the InstaWP Connect WordPress plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"instawp_connect","vendor":"instawp"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The InstaWP Connect plugin for WordPress is vulnerable to unauthorized access of data, modification of data and loss of data due to a missing capability check on the 'events_receiver' function in versions up to, and including, 0.0.9.18.
