A cross-site scripting (XSS) vulnerability in the configuration report page (adm_config_report.php) in MantisBT 1.2.13 allows remote authenticated users to inject arbitrary web script or HTML via a project name.

MantisBT 1.2.12 before 1.2.15 allows authenticated users to by the workflow restriction and close issues.

A cross-site scripting (XSS) vulnerability in MantisBT 1.2.14 allows remote attackers to inject arbitrary web script or HTML via a version, related to deleting a version.

MantisBT before 1.3.20 and 2.22.1 allows Post Authentication Command Injection, leading to Remote Code Execution.

The Timeline feature in my_view_page.php in MantisBT through 2.21.1 has a stored cross-site scripting (XSS) vulnerability, allowing execution of arbitrary code (if CSP settings permit it) after uploading an attachment with a crafted filename. The code is executed for any user having visibility to the issue, whenever My View Page is displayed.

A cross-site scripting (XSS) vulnerability in the View Filters page (view_filters_page.php) and Edit Filter page (manage_filter_edit_page.php) in MantisBT 2.1.0 through 2.17.0 allows remote attackers to inject arbitrary code (if CSP settings permit it) through a crafted PATH_INFO. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-13055.

An issue was discovered in MantisBT through 1.3.14, and 2.0.0. Using a crafted request on bug_report_page.php (modifying the 'm_id' parameter), any user with REPORTER access or above is able to view any private issue's details (summary, description, steps to reproduce, additional information) when cloning it. By checking the 'Copy issue notes' and 'Copy attachments' checkboxes and completing the clone operation, this data also becomes public (except private notes).

A cross-site scripting (XSS) vulnerability in the Edit Filter page (manage_filter_edit page.php) in MantisBT 2.1.0 through 2.17.1 allows remote attackers (if access rights permit it) to inject arbitrary code (if CSP settings permit it) through a crafted project name.

A cross-site scripting (XSS) vulnerability in the Manage Filters page (manage_filter_page.php) in MantisBT 2.1.0 through 2.17.1 allows remote attackers (if access rights permit it) to inject arbitrary code (if CSP settings permit it) through a crafted project name.

An issue was discovered in the Source Integration plugin before 1.5.9 and 2.x before 2.1.5 for MantisBT. A cross-site scripting (XSS) vulnerability in the Manage Repository and Changesets List pages allows execution of arbitrary code (if CSP settings permit it) via repo_manage_page.php or list.php.
