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-2023-28121 exists.\n\nAffected product: WooCommerce Payments WordPress Plugin. 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-2023-28121/ (Markdown: https://insights.sbomify.com/CVE-2023-28121/index.md)","id":"CVE-2023-28121","markdown":"https://insights.sbomify.com/CVE-2023-28121/index.md","name":"CVE-2023-28121","record":{"aliases":["GHSA-rw6j-4w4v-pm7m"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WooCommerce Payments plugin","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication to gain administrator access on WordPress sites using the WooCommerce Payments plugin.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"woocommerce_payments","vendor":"automattic"},{"product":"woopayments","vendor":"automattic"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-287","name":"Improper Authentication"}],"description":"An issue in WooCommerce Payments plugin for WordPress (versions 5.6.1 and lower) allows an unauthenticated attacker to send requests on behalf of an elevated user, like administrator.
