CVSS v3.1 |
| Horde IMP's AppleDouble MIME viewer writes an attacker-controlled attachment name into an HTML status block without escaping it. In lib/Mime/Viewer/Appledouble.php, _IMPrender() obtains the name of the data part with IMP_Contents::getPartName(), which returns the MIME part's own name parameter as supplied by the message, and passes it through sprintf into the text of an IMP_Mime_Status object. IMP_Mime_Status::__toString() concatenates each text entry directly into the surrounding table markup, so the value reaches the rendered page verbatim. A message crafted as multipart/appledouble whose data part carries markup in its name parameter therefore executes script in the context of any user who views it, and the payload persists in the mailbox. Exploitation requires no account on the target system, only the ability to send mail to a user. Version 7.2.0 escapes the value with htmlspecialchars(). The researcher additionally chains this flaw with the arbitrary file read of CVE-2026-58451, and reports that script running in an administrator's session can reach an application code-execution path. |
| Horde IMP before 7.0.1 contains a path traversal vulnerability in lib/Compose.php that allows authenticated attackers to read arbitrary files from the server filesystem by embedding traversal sequences after a CKEditor path prefix in img src URLs. Attackers can bypass the stripos() prefix validation by appending sequences such as traversal segments after the matching prefix, causing file_get_contents() to read sensitive files whose contents are then exfiltrated as MIME parts in outgoing email; unauthenticated exploitation is also achievable via CSRF against an active authenticated session. |
| Horde Virtual File System (VFS) API before 3.0.1 contains an OS command injection vulnerability in the Horde_Vfs_Smb driver where the _escapeShellCommand() method fails to sanitize command substitution sequences, allowing authenticated attackers to inject arbitrary shell commands through user-controlled filenames. Attackers can supply malicious filenames containing unescaped command substitution payloads through operations such as file upload, folder creation, rename, or deletion, which are interpolated into a double-quoted shell context and executed via proc_open() through /bin/sh -c before smbclient runs, resulting in arbitrary command execution on the underlying system. |
| procmail in Ingo H3 before 1.1.2 Horde module allows remote authenticated users to execute arbitrary commands via shell metacharacters in the mailbox destination of a filter rule. |
| Unspecified vulnerability in the calendar component in Horde Groupware Webmail Edition before 1.0, and Groupware before 1.0, allows remote attackers to include certain files via unspecified vectors. NOTE: some of these details are obtained from third party information. |
| Directory traversal vulnerability in lib/FBView.php in Horde Kronolith H3 before 2.0.7 and 2.1.x before 2.1.4 allows remote attackers to include arbitrary files and execute PHP code via a .. (dot dot) sequence in the view parameter. |
| IMP 2.2 and earlier allows attackers to read and delete arbitrary files by modifying the attachment_name hidden form variable, which causes IMP to send the file to the attacker as an attachment. |
| Horde library 1.02 allows attackers to execute arbitrary commands via shell metacharacters in the "from" address. |
| Horde Application Framework 3.0.9 allows remote attackers to read arbitrary files via a null character in the url parameter in services/go.php, which bypasses a sanity check. |
| Cross-site scripting (XSS) vulnerability in horde/imp/search.php in Horde IMP H3 before 4.1.3 allows remote attackers to include arbitrary web script or HTML via multiple unspecified vectors related to folder names, as injected into the vfolder_label form field in the IMP search screen. |
| index.php in Horde Application Framework before 3.1.2 allows remote attackers to include web pages from other sites, which could be useful for phishing attacks, via a URL in the url parameter, aka "cross-site referencing." NOTE: some sources have referred to this issue as XSS, but it is different than classic XSS. |
| Cross-site scripting (XSS) vulnerability in horde 3 (horde3) before 3.1.1 allows remote attackers to inject arbitrary web script or HTML via (1) templates/problem/problem.inc and (2) test.php. |
| Eval injection vulnerability in Horde Application Framework versions 3.0 before 3.0.10 and 3.1 before 3.1.1 allows remote attackers to execute arbitrary code via the help viewer. |
| Horde Groupware v5.2.22 has a user enumeration vulnerability that allows an unauthenticated attacker to determine the existence of valid accounts on the system. To exploit the vulnerability, an HTTP request must be sent to ‘/imp/attachment.php’ including the parameters ‘id’ and ‘u’. If the specified user exists, the server will return the download of an empty file; if it does not exist, no download will be initiated, which unequivocally reveals the validity of the user. |
| Horde IMP through 6.2.27, as used with Horde Application Framework through 5.2.23, allows XSS that leads to account takeover via a crafted text/html e-mail message with an onerror attribute (that may use base64-encoded JavaScript code), as exploited in the wild in March 2025. |
| Remote Code Execution was found in Horde_Image 2.x before 2.5.0 via a crafted GET request. Exploitation requires authentication. |
| A Remote Code Execution vulnerability has been found in the Horde_Image library when using the "Im" backend that utilizes ImageMagick's "convert" utility. It's not exploitable through any Horde application, because the code path to the vulnerability is not used by any Horde code. Custom applications using the Horde_Image library might be affected. This vulnerability affects all versions of Horde_Image from 2.0.0 to 2.5.1, and is fixed in 2.5.2. The problem is missing input validation of the index field in _raw() during construction of an ImageMagick command line. |
| In Horde_Crypt before 2.7.6, as used in Horde Groupware Webmail Edition through 5.2.17, OS Command Injection can occur if the attacker is an authenticated Horde Webmail user, has PGP features enabled in their preferences, and attempts to encrypt an email addressed to a maliciously crafted email address. |
| In Horde_Crypt before 2.7.6, as used in Horde Groupware Webmail Edition 5.x through 5.2.17, OS Command Injection can occur if the user has PGP features enabled in the user's preferences, and has enabled the "Should PGP signed messages be automatically verified when viewed?" preference. To exploit this vulnerability, an attacker can send a PGP signed email (that is maliciously crafted) to the Horde user, who then must either view or preview it. |
| In Horde Groupware 5.2.19, there is XSS via the Name field during creation of a new Resource. This can be leveraged for remote code execution after compromising an administrator account, because the CVE-2015-7984 CSRF protection mechanism can then be bypassed. |
