MantisBT: Stored XSS in print_all_bug_page_word.php

A missing output encoding call in print_all_bug_page_word.php allows any authenticated user to inject arbitrary HTML into an IMG tag's *alt* attribute via an image attachment with a crafted filename such as `probe." onload="alert(1)`. When any user views the HTML export page (print_all_bug_page_word.php?type_page=html&export=1), the rendered IMG tag becomes `<img src="..." alt="" onload="alert(1)" />`, breaking out of the alt attribute. ### Impact Cross-site scripting. Impact is limited by …

MantisBT: Injection of TIME_TRACKING and REMINDER Notes via REST and SOAP APIs

Unvalidated note_type Parameter in mc_issue_update SOAP Endpoint Allows creation of TIME_TRACKING and REMINDER Notes. The SOAP path passes the user-supplied note_type integer directly to bugnote_add() without validating that the user is authorized to create that type of note. If the user's access level is higher than *$g_time_tracking_view_threshold*, they can also inject arbitrary hours into billing reports. REST API also allows injection of TIME_TRACKING notes (but not REMINDER) through the s…

MantisBT: Reflected XSS in admin/install.php via unescaped printf

MantisBT 2.28.3 and earlier contains six reflected XSS injection points in `/admin/install.php`. User-supplied parameters are echoed into HTML without escaping via an unescaped printf format string. No authentication is required. A Content Security Policy (script-src 'self') prevents inline JavaScript execution, but the CSP is missing a form-action directive, allowing exploitation via credential-phishing form injection and <meta> open redirects. ### Impact - Credential phishing: Attacker craft…

MantisBT: Remote Code Execution via eval() Class Hoisting in adm_config_set.php

MantisBT 2.28.3 and earlier contains a remote code execution vulnerability in the admin "Manage Configuration" feature (adm_config_set.php). When setting a configuration value with a non-string type (integer, float, complex), the value is passed through ConfigParser -> Tokenizer, which calls *eval()* with a `return;` prefix intended to prevent code execution. However, PHP hoists function and class declarations at compile time, even past a *return* statement. An attacker can define a class in th…

MantisBT: SOAP API Authentication Bypass with Privilege Escalation to Administrator

MantisBT 2.28.3 and earlier contains a critical authentication bypass in the SOAP API's mci_check_login() function. Any user knowing any valid cookie_string can authenticate as any other user (knowing their username), including the administrator, without knowing the target's password. The vulnerability is exploitable with zero prior access on default MantisBT installations because self-registration is enabled by default ($g_allow_signup = ON). A self-registered user can use their own cookie_str…

MantisBT: SQL Injection via history_order Configuration Value

MantisBT 2.28.3 and earlier versions contains a SQL injection vulnerability in core/history_api.php. The history_order configuration value is concatenated directly into a SQL ORDER BY clause without any sanitisation, parameterization, or validation against a whitelist. An administrator can set this configuration value via the web UI (adm_config_set.php) or the REST API (PATCH /api/rest/config). The injected SQL then executes whenever any user views a bug with history entries. ### Impact - Sens…

MantisBT: Private Bugnote Attachment Content Leak via REST API

Mantis Bug Tracker (MantisBT) is an open source issue tracker. From 2.23.0 to 2.28.1, a missing authorization check in MantisBT's file visibility function allows any authenticated user (REPORTER+) to download attachments on private bugnotes they should not be able to access, via the REST API endpoint GET /api/rest/issues/{id}/files and SOAP API mc_issue_attachment_get endpoint. This vulnerability is fixed in 2.28.2.

MantisBT: Authorization Bypass in Bugnote Editing via Issue Update API

Mantis Bug Tracker (MantisBT) is an open source issue tracker. Prior to 2.28.2, the mc_issue_update() function in MantisBT allows users having update_bug_threshold access (UPDATER, with default settings) to edit, change view state, and modify time tracking on bugnotes belonging to other users — bypassing the default DEVELOPER (level 55) threshold required by the dedicated mc_issue_note_update() function. This vulnerability is fixed in 2.28.2.

MantisBT is Vulnerable to Stored XSS Through its Saved-Filter Owner Column

Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.11.0 through 2.28.1, a Stored XSS vulnerability is caused by incorrect escaping of a saved filter's owner, allowing an attacker to inject arbitrary HTML on systems where $g_show_user_realname = ON. Note that By default, only users with Manager access level or above can save their filters publicly. This issue has been fixed in version 2.28.2. If developers are unable to update immediately, they can work around this issue…

MantisBT has Potential Referer-Based Reflected HTML Injection / XSS in Tag Update Page

Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.28.1 and below, improper escaping of the redirection page (retrieved from the request's Referer header) allows an attacker to inject HTML. While this is generally not directly actionable as modern browsers will URL-encode special characters, on some specific server configurations this could poison the cache, leading to cross-site scripting. This issue has been fixed in version 2.28.2.

MantisBT has a Content Security Policy bypass via attachments

Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.28.1 and below, given any pre-existing XSS / HTML injection vulnerability, an attacker can bypass the Content Security Policy's script-src directive by uploading a crafted attachment to any issue that, when accessed via the file_download.php link, will be downloaded with a valid JavaScript MIME type resulting in script execution. The uploaded payload must be sniffed as a valid JavaScript MIME type by PHP finfo (see file…

MantisBT is Vulnerable to Stored XSS through Custom Field Textarea Values

Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions 2.28.1 and below contain flawed logic that causes improper escaping of a textarea custom field's contents in the Update Issue page, (bug_update_page.php) allowing an attacker to inject HTML and, if CSP settings permit, execute arbitrary JavaScript when the page is loaded. This facilitates session theft, leading to admin account takeover, full project data access. In order to exploit this issue, a textarea-type custom field m…

MantisBT authorization bypass allows continued access to self-uploaded attachments on private issues

Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions 2.28.1 and prior permit a user to list and download their own attachments from an Issue created by another user even after it becomes private, bypassing read access revocation. The loss of confidentiality caused by this vulnerability is minimal, considering that only attachments previously uploaded by the user themselves remain accessible. This issue has been fixed in version 2.82.2.
