A vulnerability has been found in SourceCodester CET Automated Grading System with AI Predictive Analytics 1.0. The impacted element is an unknown function of the file /index.php. The manipulation of the argument action leads to cross site scripting. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used.
The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'bookly-customer-full-name' cookie in versions up to, and including, 27.2 due to insufficient input sanitization and output escaping.

Exploitation requires 'Remember personal information in cookies' setting to be enabled (disabled by default).
The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Anchor block in versions up to, and including, 2.0.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Allegra downloadAttachment Cross-Site Scripting Authentication Bypass Vulnerability. This vulnerability allows remote attackers to execute arbitrary script on affected installations of Allegra. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the downloadAttachment method. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of arbitrary script. An attacker can leverage this vulnerability to execute script in the context of the current user. Was ZDI-CAN-28236.
Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in WPVibes WP Mail Log allows DOM-Based XSS. This issue affects WP Mail Log: from n/a through 1.0.2.
Similar SeverityMEDIUM
Linux-PAM through 1.7.2 contains an observable timing discrepancy (CWE-208) in the pam_userdb module's plaintext-password comparison path in modules/pam_userdb/pam_userdb.c that allows a local or network-adjacent attacker able to repeatedly drive authentication through a calling service to recover the plaintext password of a target account by measuring response-timing differences. The comparison uses strncmp() (or strncasecmp() when PAM_ICASE_ARG is set) preceded by a length-equality check, so the time to reject a candidate depends on the index of the first differing byte and on whether the candidate's length matches the stored password, leaking the password length and individual prefix bytes. The vulnerable path is reached when the administrator configures pam_userdb with crypt=none, with an unrecognized crypt method, or without a crypt= argument, causing the module to store and compare credentials in plaintext.
In OpenStack Ironic through 35.0.1, when applying a PATCH to update fields in volume properties the user is authorized for, Ironic can return unredacted sensitive information (such as iSCSI credentials). The PATCH outcome is a security issue; the POST outcome is not a security issue.
A vulnerability was detected in CodeAstro Student Attendance Management System 1.0. Impacted is an unknown function of the file /attendance-php/Admin/createStudents.php. Performing a manipulation of the argument admissionNumber results in sql injection. Remote exploitation of the attack is possible. The exploit is now public and may be used.
The Meow Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the REST API endpoint /wp-json/meow-gallery/v1/save_shortcode in all versions up to, and including, 5.4.4 This makes it possible for authenticated attackers, with Author-level access and above, to arbitrarily create or overwrite existing gallery shortcode records by supplying a user-controlled id value. The endpoint performs database update operations without verifying that the requesting user is authorized to modify the referenced gallery record or create their own.
