{"schema":"threatline.record/2","record":{"id":"CVE-2026-109400","aliases":[],"summary":"InstaWP Connect <= 0.1.4.1 - Authenticated (Subscriber+) Privilege Escalation via Role-as-Capability Admin Page and API Key Disclosure via 'instawp_sync_tab_roles' Role-as-Capability Setting","details":"The InstaWP Connect – 1-click WP Staging & Migration plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 0.1.4.1 This is due to the plugin registering its admin page via `add_management_page()` using a role name returned by `InstaWP_Setting::get_allowed_role()` as the required capability — which WordPress resolves as a real capability match for any user holding that role — combined with `generate_section_field()` rendering the master API key from the `instawp_api_options` option directly as the `value` attribute of a plain-text HTML input with no additional `manage_options` or equivalent capability check. This makes it possible for authenticated attackers with Subscriber-level access and above to read the plaintext master API key, use its SHA-256-derived secret as a bearer token accepted by the plugin's REST API `validate_api_request()`, and call `POST /wp-json/instawp-connect/v2/auto-login` to mint a 30-second single-use login URL that sets an administrator authentication cookie — fully escalating their privileges. Exploitation requires the site to be actively connected to InstaWP and an administrator to have added the attacker's role to the plugin's Sync Tab Access list (`instawp_sync_tab_roles`); notably, the settings tab suppression logic only hides the tab when `administrator` is absent from the list entirely, meaning a mixed configuration retaining administrator alongside a lower role still serves the full settings page — including the API key — to the lower-privileged user.","categories":["Unclassified"],"product":"InstaWP Connect – 1-click WP Staging & Migration","vendor":"instawp","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109400","source_modified_at":"2026-10-16T15:46:59.318Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"InstaWP Connect – 1-click WP Staging & Migration","vendor":"instawp","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.1.4.1","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0035,"percentile":0.27485,"score_date":"2026-10-23"},"published_at":"2026-10-16T04:27:01.115Z","modified_at":"2026-10-16T15:46:59.318Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109400","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T15:46:59.318Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109400","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/925b009e-3aeb-496d-8218-6ea5dc9d9989?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/instawp-connect/tags/0.1.4.1/includes/class-instawp-setting.php#L186"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/instawp-connect/tags/0.1.4.1/admin/class-instawp-admin.php#L153"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/instawp-connect/tags/0.1.4.1/includes/class-instawp-setting.php#L91"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/instawp-connect/tags/0.1.4.1/includes/apis/class-instawp-rest-api.php#L663"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/instawp-connect/tags/0.1.4.1/includes/class-instawp-hooks.php#L194"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/instawp-connect/tags/0.1.4.1/includes/functions.php#L1041"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3743786/instawp-connect/trunk/includes/class-instawp-setting.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-16T15:45:59.923711Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T15:46:59.318Z","content_hash":"a8cb3e05f56d9df7f4c7b72fa215159e4663f2eae90dfc97279515fb4afbc1cb"}}
