The vulnerability exists due to insufficient sanitization of user-supplied data in the module list filter within course search. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.


2) Information disclosure (CVE-ID: CVE-2025-26525)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to insufficient sanitizing in the TeX notation filter. A remote attacker can gain unauthorized access to sensitive information on sites where pdfTeX is available.


3) Improper access control (CVE-ID: CVE-2025-26526)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to feedback response viewing and deletions do not respect Separate Groups mode. A remote attacker can view or delete the responses in Feedback activities.


4) Information disclosure (CVE-ID: CVE-2025-26527)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to non-searchable tags can still be discovered on the tag search page and in the tags block. A remote user can gain unauthorized access to sensitive information on the system.


5) Improper access control (CVE-ID: CVE-2025-26531)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to the IDOR issue in badges. A remote user can disable badges they do not have permission to access.


6) Improper access control (CVE-ID: CVE-2025-26532)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A remote user can evade trusttext config when restoring glossary entries.


7) Stored cross-site scripting (CVE-ID: CVE-2025-26528)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
