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-2026-12255 exists.\n\nAffected product: Unknown MainWP Child. 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-2026-12255/ (Markdown: https://insights.sbomify.com/CVE-2026-12255/index.md)","id":"CVE-2026-12255","markdown":"https://insights.sbomify.com/CVE-2026-12255/index.md","name":"CVE-2026-12255","record":{"aliases":["GHSA-4ph4-5rpm-wrw9"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication and gain administrator access if passwordless login is enabled in the MainWP Child plugin.","user_interaction":"not_required","vuln_class":"auth_bypass"},"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-287","name":"Improper Authentication"}],"description":"The MainWP Child  WordPress plugin before 6.1.2 does not verify the requester's identity in its site-registration request handler when password authentication has been disabled for the targeted account, allowing an unauthenticated attacker to obtain a valid authentication session as that account, including an administrator, by naming its login in a single registration request.","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":"MainWP Child \u003c 6.1.2 - Unauthenticated Administrator Authentication Bypass via Passwordless Site Registration","id":"CVE-2026-12255","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Fusion Builder plugin \u003c= 3.15.3 - PHP Object Injection vulnerability","id":"CVE-2026-12256"},"packages":[],"prev":{"headline":"Netskope Client Captive Portal WebView Persistence allowing SWG bypass issue","id":"CVE-2026-12254"},"products":["MainWP Child"],"published":"2026-07-27","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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-27","vendors":["Unknown"]},"summary":"Unauthenticated attackers can bypass authentication and gain administrator access if passwordless login is enabled in the MainWP Child plugin.","url":"https://insights.sbomify.com/CVE-2026-12255/"}
