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-2026-11966 exists.\n\nAffected product: Unknown User Registration \u0026 Membership. 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-2026-11966/ (Markdown: https://insights.sbomify.com/CVE-2026-11966/index.md)","id":"CVE-2026-11966","markdown":"https://insights.sbomify.com/CVE-2026-11966/index.md","name":"CVE-2026-11966","record":{"aliases":["GHSA-2wp6-4gxm-vfvx"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can delete recently-registered user accounts by exploiting a missing capability check in the Stripe subscription handler.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The User Registration \u0026 Membership  WordPress plugin before 5.2.3 does not perform a capability check for unauthenticated callers on one of its membership payment actions and acts on a caller-supplied user identifier, allowing unauthenticated attackers to delete recently-registered, payment-pending user accounts.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"User Registration \u0026 Membership \u003c 5.2.3 - Unauthenticated Limited User Deletion via Stripe Subscription Handler","id":"CVE-2026-11966","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Arbitrary code execution in MobaXterm Personal Edition (Portable)","id":"CVE-2026-11967"},"packages":[],"prev":{"headline":"User Registration \u0026 Membership \u003c 5.2.0 - Unauthenticated Paid Membership Bypass","id":"CVE-2026-11965"},"products":["User Registration \u0026 Membership"],"published":"2026-07-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-17","vendors":["Unknown"]},"summary":"Unauthenticated attackers can delete recently-registered user accounts by exploiting a missing capability check in the Stripe subscription handler.","url":"https://insights.sbomify.com/CVE-2026-11966/"}
