Title
Photo Gallery, Sliders, Proofing and Themes <= 4.2.0 - Insecure Direct Object Reference to Authenticated (Subscriber+) Image Deletion via REST API
Summary
The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 4.2.0. This is due to insufficient object-level authorization in the image deletion REST flow where the permission callback for DELETE /imagely/v1/images/{id} only checks 'NextGEN Manage gallery' permissions and does not enforce gallery ownership or 'NextGEN Manage others gallery' permissions. This makes it possible for authenticated attackers, with Subscriber-level privileges and 'NextGEN Manage gallery' capability, to delete gallery images belonging to other users as well as their associated image files from disk when deleteImg is enabled (default).

This CVE ID has been rejected. GitLab determined that the reported behavior does not constitute a vulnerability: linking a group SAML identity requires the user to explicitly consent to that group controlling their GitLab account for sign-in, and management of group SAML identities by a group Owner is therefore expected behavior rather than an authorization bypass. No GitLab version was affected.

Title
Authorization bypass through User-Controlled key in SpiceJet Online Booking System
Summary
A vulnerability in SpiceJet’s booking API allows unauthenticated users to query passenger name records (PNRs) without any access controls. Because PNR identifiers follow a predictable pattern, an attacker could systematically enumerate valid records and obtain associated passenger names. This flaw stems from missing authorization checks on an endpoint intended for authenticated profile access.

Title
MW WP Form <= 5.1.2 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'post_id' Query Parameter
Summary
The MW WP Form plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 5.1.2 via the _get_post_property_from_querystring() function due to insufficient restrictions on which posts can be included. This makes it possible for unauthenticated attackers to extract data from password protected, private, or draft posts that they should not have access to.

Title
Oliver POS <= 2.4.2.6 - Unauthenticated Authorization Bypass Through User-Controlled Key to 'OliverAuth' Header
Summary
The Oliver POS – A WooCommerce Point of Sale (POS) plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.4.2.6. The plugin protects its entire /wp-json/pos-bridge/* REST API namespace through the oliver_pos_rest_authentication() permission callback, which uses a loose PHP comparison (==) to compare the attacker-supplied 'OliverAuth' header value against the 'oliver_pos_authorization_token' option. On fresh installations where the admin has not yet completed the connection flow, this option is unset (get_option returns false). Due to PHP's type juggling, the loose comparison '0' == false evaluates to true, allowing an unauthenticated attacker to bypass authentication by sending 'OliverAuth: 0'. This grants full access to all POS API endpoints, enabling attackers to read user data (including administrator details), update user profiles (including email addresses), and delete non-admin users. An admin account email reset can lead to site takeover.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
