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-2026-18366 exists.\n\nAffected product: Unknown Events Manager. 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-2026-18366/ (Markdown: https://insights.sbomify.com/CVE-2026-18366/index.md)","id":"CVE-2026-18366","markdown":"https://insights.sbomify.com/CVE-2026-18366/index.md","name":"CVE-2026-18366","record":{"aliases":["GHSA-gpp5-qcrv-vm9j"],"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":"none","summary":"Unauthenticated attackers can escalate privileges to Administrator or delete accounts by exploiting flawed capability mapping in the Events Manager plugin.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-269","name":"Improper Privilege Management"}],"description":"The Events Manager  WordPress plugin before 7.4.1 does not properly scope its capability mapping, discarding the access control decisions WordPress already made for unrelated privileged actions, which allows unauthenticated users to change the password of, escalate to Administrator, or delete any account whose user ID happens to match the ID of one of the Events Manager  WordPress plugin before 7.4.1's own posts.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-16","github_poc":3,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-16T20:21:02Z","kind":"github_poc","ref":"https://github.com/Nxploited/CVE-2026-18366","stars":2,"title":"Events Manager \u003c 7.4.1 - Unauthenticated Privilege Escalation to Administrator"},{"date":"2026-08-20T18:32:56Z","kind":"github_poc","ref":"https://github.com/ghostpels/CVE-2026-18366","stars":0,"title":"CVE-2026-18366: Events Manager \u003c 7.4.1 — Unauthenticated Privilege Escalation to Administrator.
