Intermesh Group-Office before 6.8.181, 25.0.116, and 26.0.58 contains a missing authorization vulnerability that allows authenticated users to download form reports via api/download.php without permission checks. Attackers can request the business/forms/report blob with a form ID to export every submission as an XLSX file, disclosing submissions they are not permitted to see.

Group-Office before 6.8.181, 25.0.116, and 26.0.58 Local File Read via processUploadQueue

Group-Office before 6.8.181, 25.0.116, and 26.0.58 contains an arbitrary local file read vulnerability in FolderController::actionProcessUploadQueue that allows authenticated users to read server files by supplying absolute paths in the blobs parameter. Attackers can have files hard-linked or copied into their own folder and downloaded, exposing other users' stored files and config.php database credentials.

Group-Office before 6.8.181, 25.0.116, and 26.0.58 Stored XSS via filterXSS Bypass

Intermesh Group-Office before 6.8.181, 25.0.116, and 26.0.58 contains a stored cross-site scripting vulnerability in the email viewer due to a flawed regex in StringHelper::filterXSS. Remote attackers can send emails containing tags like svg/onload, which MessagePanel.js renders raw, executing script in the recipient's session when opened.

Intermesh Group-Office < 3.5.5 Path Traversal via compress.php

Intermesh Group-Office 3.3.0 before 3.5.5 contains an unauthenticated path traversal vulnerability in compress.php that allows remote attackers to read arbitrary files by manipulating the 'file' parameter. Attackers can send GET requests to /compress.php with '../' sequences in the 'file' parameter, which is appended to the cache path and passed to readfile(), to read files such as /etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-21.

Group-Office: Authenticated Stored XSS in Administrator Context via Arbitrary Cross-User Setting Write

Group-Office is an enterprise customer relationship management and groupware tool. Prior to 26.0.25, 25.0.100, and 6.8.165, GroupOffice allows authenticated users to persist arbitrary legacy settings for any user_id via index.php?r=core/saveSetting. A separate client-side sink in the email module injects the email_font_size setting directly into JavaScript without escaping. By combining these two issues, any low-privileged authenticated user can overwrite an administrator's email_font_size setting with a JavaScript payload and trigger stored XSS in the administrator's browser when the GroupOffice web client loads views/Extjs3/modulescripts.php. This vulnerability is fixed in 26.0.25, 25.0.100, and 6.8.165.

Authenticated SQL Injection in Contact/query addressBookIds filter

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.158, 25.0.92, and 26.0.17, an authenticated SQL Injection vulnerability in the JMAP `Contact/query` endpoint allows any authenticated user with basic addressbook access to extract arbitrary data from the database — including active session tokens of other users. This enables full account takeover of any user, including the System Administrator, without knowing their password. Versions 6.8.158, 25.0.92, and 26.0.17 fix the issue.

Group-Office has stored XSS vulnerability via unsanitized filenames

Group-Office is an enterprise customer relationship management and groupware tool. In versions 6.8.148 and below, and 25.0.1 through 25.0.79, the application stores unsanitized filenames in the database, which can lead to Stored Cross-Site Scripting (XSS). Users who interact with these specially crafted file names within the Group-Office application are affected. While the scope is limited to the file-viewing context, it could still be used to interfere with user sessions or perform unintended actions in the browser. This issue is fixed in versions 6.8.149 and 25.0.80.

Group-Office Argument Injection in MaintenanceController::actionZipLanguage

Group-Office is an enterprise customer relationship management and groupware tool. Prior to 6.8.150, 25.0.82, and 26.0.5, the MaintenanceController exposes an action zipLanguage which takes a lang parameter and passes it directly to a system zip command via exec(). This can be combined with uploading a crafted zip file to achieve remote code execution. This vulnerability is fixed in 6.8.150, 25.0.82, and 26.0.5.

Group-Office is vulnerable to RCE due to Command Injection via TNEF Attachment Handler

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.150, 25.0.82, and 26.0.5, there is a remote code execution (RCE) vulnerability in Group-Office. The endpoint email/message/tnefAttachmentFromTempFile directly concatenates the user-controlled parameter tmp_file into an exec() call. By injecting shell metacharacters into tmp_file, an authenticated attacker can execute arbitrary system commands on the server. This issue has been patched in versions 6.8.150, 25.0.82, and 26.0.5.

Group-Office is vulnerable to SSRF and File Read in WOPI service discovery

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.150, 25.0.82, and 26.0.5, an authenticated user within the System Administrator group can trigger a full SSRF via the WOPI service discovery URL, including access to internal hosts/ports. The SSRF response body can be exfiltrated via the built‑in debug system, turning it into a visible SSRF. This also allows full server-side file read. This issue has been patched in versions 6.8.150, 25.0.82, and 26.0.5.

Group-Office Has Authenticated SQL Injection in advancedQueryData.comparator

Group-Office is an enterprise customer relationship management and groupware tool. Versions prior to 26.0.8, 25.0.87, and 6.8.153 have a SQL Injection (SQLi) vulnerability, exploitable through the `advancedQueryData` parameter (`comparator` field) on an authenticated endpoint. The endpoint `index.php?r=email/template/emailSelection` processes `advancedQueryData` and forwards the SQL comparator without a strict allowlist into SQL condition building. This enables blind boolean-based exfiltration of the `core_auth_password` table. Versions 26.0.8, 25.0.87, and 6.8.153 fix the issue.

Group-Office Vulnerable to Remote Code Execution (RCE)

Group-Office is an enterprise customer relationship management and groupware tool. Versions prior to 26.0.9, 25.0.87, and 6.8.154 have an authenticated Remote Code Execution vulnerability in the TNEF attachment processing flow. The vulnerable path extracts attacker-controlled files from `winmail.dat` and then invokes `zip` with a shell wildcard (`*`). Because extracted filenames are attacker-controlled, they can be interpreted as `zip` options and lead to arbitrary command execution. Versions 26.0.9, 25.0.87, and 6.8.154 fix the issue.

Group-Office: Self XSS in GroupOffice Installer License Page (install/license.php)

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.155, 25.0.88, and 26.0.10, there is a reflected XSS vulnerability in the GroupOffice installer, endpoint install/license.php. The POST field license is rendered without escaping inside a <textarea>, allowing a </textarea><script>...</script> breakout.. This issue has been patched in versions 6.8.155, 25.0.88, and 26.0.10.

Group-Office: Reflected XSS in JavaScript context

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.155, 25.0.88, and 26.0.10, there is a reflected XSS vulnerability in GroupOffice on the external/index flow. The f parameter (Base64 JSON) is decoded and then injected into an inline JavaScript block without strict escaping, allowing </script><script>...</script> injection and arbitrary JavaScript execution in the victim's browser. This issue has been patched in versions 6.8.155, 25.0.88, and 26.0.10.

Group-Office: Authenticated Remote Code Execution via PHP Insecure Deserialization in `AbstractSettingsCollection`

Group-Office is an enterprise customer relationship management and groupware tool. Prior to versions 6.8.156, 25.0.90, and 26.0.12, a vulnerability in the AbstractSettingsCollection model leads to insecure deserialization when these settings are loaded. By injecting a serialized FileCookieJar object into a setting string, an authenticated attacker can achieve Arbitrary File Write, leading directly to Remote Code Execution (RCE) on the server. This issue has been patched in versions 6.8.156, 25.0.90, and 26.0.12.
