CVE-2026-89079The Theme My Login plugin for WordPress is vulnerable to privilege escalation via account takeover in versions up to, and including, 7.2.1. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords on multi-site setups in certain configurations.

CVE-2026-103768The ELEX WordPress HelpDesk & Customer Ticketing System plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.3.7 via the initMailPart function. This is due to insufficient file type validation when saving IMAP email attachments. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.

CVE-2026-109515The MailOptin – Popup, Optin Forms & Email Newsletters for Mailchimp, HubSpot, AWeber Etc. plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2.78.6 This is due to the `subscribe_to_email_list` endpoint accepting an attacker-supplied `optin_data[form_custom_field_mappings]` parameter without any allow-list validation on destination keys, allowing the attacker-controlled mapping to override the administrator's saved mapping and pass arbitrary `wp_users` column names — including `ID` and `user_pass` — directly into `wp_insert_user()` via the `subscribe()` function. This makes it possible for unauthenticated attackers to force `wp_insert_user()` into UPDATE mode on any existing account by supplying a target user's numeric `ID`, overwrite that account's password with a pre-hashed value of their choosing, and thereby take over any WordPress user account — including administrators — leading to full site compromise. Exploitation requires that a WordPress User Registration opt-in form is published somewhere on the site, though the form's UUID is visible in page source and no authentication, nonce, or capability check is required to reach the vulnerable endpoint.

CVE-2026-104798The My Calendar – Accessible Event Manager plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.8.7. The public `mcs` GET parameter is reflected into post content unsanitized before WordPress core's `do_shortcode` filter runs, allowing an unauthenticated attacker to inject a nested `[my_calendar above=...]` shortcode; `mc_generate_calendar_nav()` then splits the `above` attribute on commas and dispatches each element via `call_user_func()` with no authentication, authorization, or callable allowlist check. This makes it possible for unauthenticated attackers to invoke arbitrary loaded PHP functions, enabling a call chain in which the shortcode `$params` array is passed to `edit_user()` — which PHP coerces to integer `1` as the `$user_id` argument — overwriting the credentials of the initial Administrator account (user ID 1) and granting the attacker full wp-admin access. Exploitation is trivially reachable via the plugin's auto-generated `/my-calendar/` page, which is publicly accessible by default upon plugin activation.

CVE-2026-111444Wheels through 4.1.2 allows SQL injection on MySQL/MariaDB with backslash escaping enabled (NO_BACKSLASH_ESCAPES absent) when an application supplies request data to inline-literal paths. These include opt-in parameterize=false queries and IN lists, and positions in developer-written where strings that the parser does not bind, such as BETWEEN bounds, function arguments and LIKE ESCAPE literals. Doubling single quotes without accounting for backslash escapes allows a value to alter the query. Bound paths are not affected; whereBetween() is bound from 4.1.2. This is fixed in 4.2.0.
