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-2026-11961 in the wild and no public exploit code.\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-2026-11961/ (Markdown: https://insights.sbomify.com/CVE-2026-11961/index.md)","id":"CVE-2026-11961","markdown":"https://insights.sbomify.com/CVE-2026-11961/index.md","name":"CVE-2026-11961","record":{"aliases":["GHSA-55mp-h634-7h25"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can register with arbitrary membership tiers to gain elevated roles, including administrator, in the User Registration \u0026 Membership plugin.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"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:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The User Registration \u0026 Membership  WordPress plugin before 5.2.3 does not validate that the membership tier submitted during public registration is one of the tiers allowed by the registration form before assigning that tier's associated user role, allowing unauthenticated users to register into an arbitrary published membership tier and obtain its role — up to administrator when such a tier exists.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-07","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-07T04:19:01Z","kind":"github_poc","ref":"https://github.com/JohenLastGen-JLG/CVE-2026-11961","stars":1,"title":"CVE-2026-11961 — UserRegistration: WordPress User Registration \u003c= 5.2.2 Privilege Escalation.
