An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-81431 in the wild and no public exploit code.\n\nAffected product: Unknown Registration Form for WooCommerce. 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-2026-81431/ (Markdown: https://insights.sbomify.com/CVE-2026-81431/index.md)","id":"CVE-2026-81431","markdown":"https://insights.sbomify.com/CVE-2026-81431/index.md","name":"CVE-2026-81431","record":{"aliases":["GHSA-rg35-vr3j-6cfx"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Contributors can escalate privileges to Administrator by exploiting unvalidated form IDs during registration, leading to full site takeover.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The Registration Form for WooCommerce WordPress plugin before 1.1.3 does not validate that the form referenced during registration is a legitimate registration form, reading the permitted-role allow-list from an arbitrary attacker-controlled post instead.
