CVE Summary Severity CVSS EPSS Priority Signals
CVE-2023-5949 The SmartCrawl WordPress plugin before 3.8.3 does not prevent unauthorised users from accessing password-protected posts' content. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available. HIGH 7.5 0.8% 58
PoC No patch
CVE-2022-1009 The Smush WordPress plugin before 3.9.9 does not sanitise and escape a configuration parameter before outputting it back in an admin page when uploading a malicious preset configuration, leading to a. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available. MEDIUM 6.1 0.8% 50
PoC No patch
CVE-2026-15748 Unauthenticated arbitrary file upload leading to remote code execution affects the Forminator Forms WordPress plugin (WPMU DEV) in all versions through 1.56.1. The public form-submission handler trusts attacker-controlled upload field configuration injected through a forged Select field value, and the dangerous-extension blocklist in handle_file_upload uses exact-key matching that is bypassed with pipe-alternative MIME type keys, letting an attacker drop an executable PHP file on the server. Reported by Wordfence and carrying a CVSS 9.8, this is a critical, network-reachable flaw with no authentication barrier, though there is no public exploit identified at time of analysis. CRITICAL 9.8 1.2% 50
No patch
CVE-2026-83627 Remote code execution in the Hummingbird performance/caching plugin for WordPress (versions up to and including 3.21.0) lets unauthenticated attackers write arbitrary PHP into a web-accessible debug-log file and execute it with a single anonymous request. The plugin's protective '<?php die(); ?>' header is silently dropped due to a PHP namespace bug in a class_exists() check, and unsanitized cookie names are written straight into wp-content/wphb-logs/page-caching-log.php. Reported by Wordfence with no public exploit identified at time of analysis; exploitation depends on a non-default Debug Log configuration. CRITICAL 9.8 0.8% 50
No patch
CVE-2026-76581 Authentication bypass in the WPMU DEV Dashboard WordPress plugin (all versions through 5.0.1) lets an unauthenticated attacker forge a valid administrator session by abusing an HMAC signature-verification flaw in the Hub SSO login flow. Because the signing routine in the unauthenticated wdpsso_step1 action covers a different, unseparated field concatenation than the verifier in wdpsso_step2, an attacker can obtain a legitimately signed token and replay it with fields rearranged to authenticate as admin. No public exploit is identified at time of analysis, but the network-reachable, unauthenticated nature and 9.8 CVSS make this a high-priority patch item. CRITICAL 9.8 0.3% 49
No patch
CVE-2023-5089 The Defender Security WordPress plugin before 4.1.0 does not prevent redirects to the login page via the auth_redirect WordPress function, allowing an unauthenticated visitor to access the login. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available. MEDIUM 5.3 2.2% 46
PoC No patch
CVE-2024-0368 The Hustle - Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.8.3 via hardcoded API Keys. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Insufficiently Protected Credentials vulnerability could allow attackers to obtain user credentials due to weak protection mechanisms. HIGH 8.6 1.3% 44
CVE-2024-7052 The Forminator Forms WordPress plugin before 1.38.3 does not sanitise and escape some of its settings, which could allow high privilege users such as Admin to perform Stored Cross-Site Scripting. Rated medium severity (CVSS 4.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available. MEDIUM 4.8 0.1% 44
PoC No patch
CVE-2024-10402 The Forminator Forms - Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available. HIGH 8.8 0.5% 44
No patch
CVE-2021-4425 The Defender Security plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.4.6. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available. MEDIUM 4.3 0.2% 42
PoC
CVE-2026-15459 Authentication bypass in WPMU DEV Dashboard (WordPress plugin) versions up to and including 5.0.0 enables unauthenticated remote attackers to invoke privileged Hub actions - including remote code execution by installing a plugin from an attacker-controlled URL, takeover of an administrator account via SSO, deletion of plugins and themes, and forced WordPress core upgrades - on any site not yet connected to the WPMU DEV Hub. The default post-installation state is unconnected, meaning every fresh installation is immediately exposed until Hub onboarding is completed. No public exploit or CISA KEV listing has been identified at time of analysis, though the impact ceiling (unauthenticated RCE) and the breadth of default-state exposure make this a high-priority remediation target. HIGH 8.1 0.5% 41
No patch
CVE-2017-15079 The Smush Image Compression and Optimization plugin before 2.7.6 for WordPress allows directory traversal. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available. HIGH 7.5 0.9% 38
No patch
CVE-2026-5192 Path Traversal in Forminator Forms plugin allows unauthenticated remote attackers to read arbitrary files from WordPress servers, potentially exposing database credentials, configuration files, and sensitive user data. Exploitation requires a publicly accessible form with File Upload field and specific 'Save and Continue' behavior settings enabled. CVSS 7.5 (High) with network vector and no authentication required. No CISA KEV listing or public exploit identified at time of analysis, suggesting limited active exploitation despite high theoretical severity. HIGH 7.5 0.0% 38
No patch
CVE-2026-18323 Stored Cross-Site Scripting in the Forminator Forms WordPress plugin (all versions through 1.57.0.2) allows unauthenticated attackers to inject persistent JavaScript payloads that auto-execute in the WordPress admin panel when an administrator views the Submissions page. The attack vector is the Save-and-Continue draft AJAX endpoint, which is registered without privilege checks (nopriv), bypassing radio field option-membership validation and permitting arbitrary values to be stored. Payload execution is triggered automatically via the bundled Inputmask library's data-attribute callback binding, requiring no further attacker interaction after initial injection. No public exploit code or CISA KEV listing is identified at time of analysis, though the unauthenticated, zero-complexity attack path and high-value admin-panel target represent meaningful real-world risk. HIGH 7.2 0.3% 36
No patch
CVE-2026-18324 Stored Cross-Site Scripting in the Forminator Forms WordPress plugin (all versions through 1.57.0.1) enables unauthenticated attackers to inject persistent malicious scripts via Rich-Text Textarea fields, which execute in any visitor's or administrator's browser upon page access. The flaw originates from insufficient input sanitization at submission time and missing output escaping at render time, with vulnerable code paths confirmed across multiple plugin files including textarea.php, abstract-class-front-action.php, and admin-page-entries.php. A patched release (1.57.0.2) is confirmed available via the WordPress plugin repository changeset; no public exploit code or CISA KEV listing has been identified at time of analysis. HIGH 7.2 0.3% 36
