Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-11963 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-2026-11963/ (Markdown: https://insights.sbomify.com/CVE-2026-11963/index.md)","id":"CVE-2026-11963","markdown":"https://insights.sbomify.com/CVE-2026-11963/index.md","name":"CVE-2026-11963","record":{"aliases":["GHSA-qxg2-gwhj-546g"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated users can modify other users' roles and membership tiers due to missing authorization checks in the User Registration \u0026 Membership plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[],"description":"The User Registration \u0026 Membership  WordPress plugin before 5.2.2 does not perform an authorization check on a membership-upgrade action and derives the user to modify from a caller-supplied identifier instead of the current user, allowing any authenticated user such as a subscriber to change another user's WordPress role and membership tier.","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 5.2.2 - Subscriber+ Cross-User Role and Membership Tier Modification via IDOR","id":"CVE-2026-11963","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":"Business logic in User Registration \u0026 Membership","id":"CVE-2026-11964"},"packages":[],"prev":{"headline":"FileOrganizer \u003c 1.2.0 - Authenticated Arbitrary File Upload via elFinder File Operations","id":"CVE-2026-11962"},"products":["User Registration \u0026 Membership"],"published":"2026-07-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-13","vendors":["Unknown"]},"summary":"Authenticated users can modify other users' roles and membership tiers due to missing authorization checks in the User Registration \u0026 Membership plugin.","url":"https://insights.sbomify.com/CVE-2026-11963/"}
