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. |
| Cross-site scripting (XSS) vulnerability in MIME/MIME/Contents.php in the MIME library in Horde 3.2.x before 3.2.2 allows remote attackers to inject arbitrary web script or HTML via the filename of a MIME attachment in an e-mail message. |
| Cross-site scripting (XSS) vulnerability in (1) Text_Filter/Filter/xss.php in Horde 3.1.x before 3.1.9 and 3.2.x before 3.2.2 and (2) externalinput.php in Popoon r22196 and earlier allows remote attackers to inject arbitrary web script or HTML by using / (slash) characters as replacements for spaces in an HTML e-mail message. |
| Unspecified vulnerability in the Horde API in Horde 3.1 before 3.1.6 and 3.2 before 3.2 before 3.2-RC2; Turba H3 2.1 before 2.1.6 and 2.2 before 2.2-RC2; Kronolith H3 2.1 before 2.1.7 and H3 2.2 before 2.2-RC2; Nag H3 2.1 before 2.1.4 and 2.2 before 2.2-RC2; Mnemo H3 2.1 before 2.1.2 and 2.2 before 2.2-RC2; Horde Groupware 1.0 before 1.0.3 and 1.1 before 1.1-RC2; and Groupware Webmail Edition 1.0 before 1.0.4 and 1.1 before 1.1-RC2 has unknown impact and attack vectors. |
| Multiple cross-site scripting (XSS) vulnerabilities in Horde Application Framework 3.2 before 3.2.5 and 3.3 before 3.3.5; Groupware 1.1 before 1.1.6 and 1.2 before 1.2.4; and Groupware Webmail Edition 1.1 before 1.1.6 and 1.2 before 1.2.4; allow remote attackers to inject arbitrary web script or HTML via the (1) crafted number preferences that are not properly handled in the preference system (services/prefs.php), as demonstrated by the sidebar_width parameter; or (2) crafted unknown MIME "text parts" that are not properly handled in the MIME viewer library (config/mime_drivers.php). |
| Multiple cross-site scripting (XSS) vulnerabilities in Horde before 3.0.7 allow remote attackers to inject arbitrary web script or HTML via the (1) gzip/tar and (2) css MIME viewers, which do not filter or escape dangerous HTML when extracting and displaying attachments. |
| 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. |
| services/go.php in Horde Application Framework 3.0.0 through 3.0.10 and 3.1.0 through 3.1.1 does not properly restrict its image proxy capability, which allows remote attackers to perform "Web tunneling" attacks and use the server as a proxy via (1) http, (2) https, and (3) ftp URL in the url parameter, which is requested from the server. |
| 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. |
| Horde library 1.02 allows attackers to execute arbitrary commands via shell metacharacters in the "from" address. |
| Horde before 2.2.4 allows remote malicious web sites to steal session IDs and read or create arbitrary email by stealing the ID from a referrer URL. |
| Multiple cross-site scripting (XSS) vulnerabilities in Horde 3.0 allow remote attackers to inject arbitrary web script or HTML via the (1) group parameter to prefs.php or (2) url parameter to index.php. |
| The default installation of Horde 3.0.4 contains an administrative account with a blank password, which allows remote attackers to gain access. |
| Unspecified cross-site scripting (XSS) vulnerability in Horde before 2.2.9 allows remote attackers to inject arbitrary web script or HTML via "not properly escaped error messages". |
| 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. |
| Multiple cross-site scripting (XSS) vulnerabilities in Horde Application Framework 3.0.0 through 3.0.10 and 3.1.0 through 3.1.1 allow remote attackers to inject arbitrary web script or HTML via a (1) javascript URI or an external (2) http, (3) https, or (4) ftp URI in the url parameter in services/go.php (aka the dereferrer), (5) a javascript URI in the module parameter in services/help (aka the help viewer), and (6) the name parameter in services/problem.php (aka the problem reporting screen). |
| Multiple cross-site scripting (XSS) vulnerabilities in Horde Application Framework before 3.0.8 allow remote authenticated users to inject arbitrary web script or HTML via multiple vectors, as demonstrated by (1) the identity field, (2) Category and (3) Label search fields, (4) the Mobile Phone field, and (5) Date and (6) Time fields when importing CSV files, as exploited through modules such as (a) Turba Address Book, (b) Kronolith, (c) Mnemo, and (d) Nag. |
| Cross-site scripting vulnerability in status.php3 for IMP 2.2.8 and HORDE 1.2.7 allows remote attackers to execute arbitrary web script and steal cookies of other IMP/HORDE users via the script parameter. |
| 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. |
| 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. |
