CVE-2026-116563

Photo Gallery, Sliders, Proofing and Themes <= 4.5.4 - Unauthenticated Stored DOM-Based Cross-Site Scripting via Comment `title` Attribute via Shutter Lightbox innerHTML

The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.5.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the site to have Shutter or Shutter Reloaded selected as the active lightbox, and the injected comment must be approved through WordPress's standard moderation workflow before the payload is rendered to other visitors.

SEOPress <= 10.3 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'display_name' Profile Field via %%archive_title%% Template Tag

The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name' parameter in all versions up to, and including, 10.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by any Subscriber who sets their display_name to a string containing the literal %%archive_title%% token alongside HTML event-handler payloads, as WordPress stores display names without HTML filtering and the plugin substitutes the token after escaping has already occurred.

Relevanssi <= 4.28.5 - Unauthenticated Stored Cross-Site Scripting via Comment Content via Late Entity Decode

The Relevanssi – A Better Search plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.28.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the site to have both the comment indexing and comment highlighting options enabled, and the payload only fires when a visitor reaches a singular page via a Relevanssi search-result permalink carrying the highlight query parameter.

PPWP <= 1.9.26 - Unauthenticated Stored Cross-Site Scripting via '[ppwp]' Shortcode 'desc_below_form' Attribute via Placeholder Marker Collision

The PPWP – Password Protect Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment / shortcode attribute desc_below_form (and placeholder as the marker-smuggling helper)' parameter in all versions up to, and including, 1.9.26 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by unauthenticated attackers because WordPress's comment_content filter leaves bare shortcode text (containing no HTML tags) untouched, and the comment_whitelist setting auto-approves subsequent comments from a previously approved name and email without administrator intervention.

CVE-2026-115840

VikRentCar Car Rental Management System <= 1.4.9 - Unauthenticated Stored Cross-Site Scripting via 'poplink' Parameter

The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'poplink' parameter in all versions up to, and including, 1.4.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The handler requires only a WordPress nonce (vikwp_nonce), which the plugin itself emits to unauthenticated visitors on the public booking-confirmation page, allowing an attacker to obtain a valid token without any account.

W3 Total Cache <= 2.10.7 - Unauthenticated Stored Cross-Site Scripting via Comment Content Cached as HTML after License Expiry

The W3 Total Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 2.10.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that a Pro license was previously active with REST caching enabled and has since become inactive while Disk Enhanced page caching remains configured, and that the attacker holds a previously approved commenter identity.

CVE-2026-111070

Content Pilot <= 2.2.4 - Unauthenticated Stored Cross-Site Scripting via RSS-linked article `<meta name="description">`

The Content Pilot – Autoblogging & Affiliate Marketing Suite plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.2.4. This is due to the plugin extracting the HTML meta description from each remotely-fetched article (WPCP_Readability::parse_meta()), piping that value through the article template substitution and html_entity_decode() in WPCP_Module::insert_post(), and then calling wp_insert_post() after switching the current user to the configured campaign author (an Administrator with the unfiltered_html capability by default) — so no wp_kses_post sanitization is applied to the attacker-controlled HTML before it is persisted as post_content and rendered on the front end. This makes it possible for unauthenticated attackers who control the content of any RSS source an administrator has configured a Content Pilot RSS campaign to consume to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Ninja Forms <= 3.15.5 - Unauthenticated Stored Cross-Site Scripting via 'extra' Parameter via Metadata Key Normalization

The Ninja Forms – Contact Form Builder with Calculators, Quizzes, Signatures & AI Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'formData.extra' parameter in all versions up to, and including, 3.15.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The nf_ajax_submit endpoint issues a valid nonce to any requester on failure, effectively neutralizing the nonce check and making exploitation trivially achievable in a single unauthenticated request.

CVE-2026-107759

WPO365 | MICROSOFT 365 GRAPH MAILER <= 6.2 - Unauthenticated Stored Cross-Site Scripting via Email Subject via wp_mail

The WPO365 | MICROSOFT 365 GRAPH MAILER plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Subject (via wp_mail/PHPMailer, e.g. CF7 your-subject)' parameter in all versions up to, and including, 6.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is stored without authentication via any mail-sending feature that forwards a submitter-controlled subject (e.g. a Contact Form 7 form) when the Graph Mailer is enabled but OAuth authorization has not been completed, a default state immediately after plugin activation.

PDF Invoices & Packing Slips for WooCommerce <= 5.16.4 - Unauthenticated Stored Cross-Site Scripting via Billing First Name / Last Name / Company / Customer Note fields at guest checkout

The PDF Invoices & Packing Slips for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'billing_address.first_name / last_name / company, customer_note' parameter in all versions up to, and including, 5.16.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is an incomplete fix for CVE-2026-92244: the wp_kses() allow-list introduced in 5.16.2 correctly blocks raw-tag payloads but is bypassed by entity-encoded payloads (e.g., &lt;img onerror=…&gt;) that contain no literal angle-bracket characters and are therefore passed through unmodified before the trailing decode rematerializes them.

FlexStock <= 3.17.2 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'post_content' Parameter via REST update endpoint

The FlexStock – Product Stock Sync with Google Sheets for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'products[].post_content' parameter in all versions up to, and including, 3.17.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by any Subscriber-level user because the plugin's admin_enqueue_scripts callback exposes the REST bearer token in the Dashboard page source via wp_localize_script() without a capability check, and the REST endpoint's permission_callback validates only that bearer token rather than performing a current_user_can() capability check.

The SureCart – Ecommerce Made Easy For Selling Physical Products, Digital Downloads, Subscriptions, Donations, & Payments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.9.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful execution requires the injected comment to be visible on a page that loads SureCart's web-component bundle (e.g. a page containing a SureCart Buy Button block), and the comment must be auto-approved or approved by a moderator.

User Frontend <= 4.3.13 - Reflected Cross-Site Scripting via 'field_attr[required]' Parameter

The User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'field_attr[required]' parameter in all versions up to, and including, 4.3.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The nonce check on the wpuf_get_child_cat AJAX action is not an effective security barrier because the wpuf_nonce value is publicly localized to every anonymous visitor of any page containing a WPUF shortcode, making it freely harvestable by an unauthenticated attacker.

Ninja Forms <= 3.15.5 - Reflected DOM-Based Cross-Site Scripting via 'querystring:<key>' URL Parameter

The Ninja Forms – Contact Form Builder with Calculators, Quizzes, Signatures & AI Form Builder plugin for WordPress is vulnerable to Reflected DOM-Based Cross-Site Scripting via 'querystring:<key>' URL Parameter in all versions up to, and including, 3.15.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This bypass is triggered when an attacker supplies a matching field:&lt;key&gt; URL parameter that causes the server to fully resolve the {field:*} placeholder, forcing the client-side else-branch to abandon the server-sanitized value and reconstruct field content from the raw query string.

Quay: ldap referral filter injection in quay external ldap authentication

A flaw was found in Red Hat Quay's external Lightweight Directory Access Protocol (LDAP) authentication handling. When an LDAP referral is returned during authentication, the system does not properly escape the username input. This allows an attacker to inject LDAP filter metacharacters, enabling user-existence oracle attacks at the referral Directory Name (DN). This could also potentially influence which DN is used for password binding in multi-domain Active Directory environments.
