Unsafe echo of filename in phpMyFAQ\phpmyfaq\admin\attachments.php leading to allow execute JavaScript code in client side (XSS)
Details
On that snippet code of rendering the file attachments from user tables
<?php foreach ($crumbs as $item) : ?>
<tr id="attachment_<?= $item->id ?>" title="<?= $item->thema ?>">
<td><?= $item->id ?></td>
<td><?= $item->filename ?></td>
<td><?= $item->record_lang ?></td>
<td><?= Utils::formatBytes($item->filesize) ?></td>
<td><?= $item->mime_type ?></td>
<td>
The data directly rendering with short hand echo without any sanitation first, its recommend to use existing class of Strings::htmlentities on use phpMyFAQ\Strings;
<td><?= Strings::htmlentities($item->filename); ?></td>
<td><?= Strings::htmlentities($item->record_lang); ?></td>

<td><?= Strings::htmlentities($item->mime_type); ?></td>
Propose fixing on that pull request https://github.com/thorsten/phpMyFAQ/pull/2827
PoC
- An attacker with permission will upload the attachments image on http://{base_url}/admin/?action=editentry
- On endpoint of ajax upload image POST /admin/index.php?action=ajax&ajax=att&ajaxaction=upload
- Change the originally name file on parameters filename to a XSS payload
-
The XSS will trigger on attachment pages /admin/?action=attachments
-
Trigger XSS
-
Payload XSS
Impact
This vulnerability will allow an attacker with a permissions of uploading an attachment to storing the payload of XSS on database specific table faqattachment columns filename.
The XSS payload could be rendering on page that listing the file on tables, and impact to others user that on the hierarchy.
The payload XSS have several attack scenario such like
- Stealing the cookies (isn’t possible since HttpOnly)
- Crashing the application with a looping javascript payload

GHSA-7VPR-JM38-WR7W
Vulnerability from github – Published: 2025-12-10 15:46 – Updated: 2025-12-11 15:47Impact
A reflected XSS vulnerability in XWiki allows an attacker to send a victim to a URL with a deletion confirmation message on which the attacker-supplied script is executed when the victim clicks the "No" button. When the victim has admin or programming right, this allows the attacker to execute basically arbitrary actions on the XWiki installation including remote code execution.
Patches
This vulnerability has been patched in XWiki 16.10.10, 17.4.2 and 17.5.0 by using the affected URL parameter only in the intended context.
Workarounds
The patch can be manually applied to the templates that are present in the WAR. A restart of XWiki is needed for the changes to be applied.

GHSA-833M-37F7-JQ55
Vulnerability from github – Published: 2024-02-08 18:46 – Updated: 2024-10-16 17:25Impact
A vulnerability has been identified in which unauthenticated cross-site scripting (XSS) in the API Server's public API endpoint can be exploited. This can lead to an attacker exploiting the vulnerability to trigger JavaScript code and execute commands remotely.
The attack vector was identified as a Reflected XSS.
API Server propagates malicious payloads from user input to the UI, which renders the output. For example, a malicious URL gets rendered into a script that is executed on a page.
The changes addressed by this fix are:
- Encode input that comes from the request URL before adding it to the response.
- The request input is escaped by changing the URL construction that is used for links to use url.URL.
- The request input is escaped by escaping the JavaScript and CSS variables with attribute encoding as defined by OWASP.

Mitigation
Carefully check each input parameter against a rigorous positive specification (allowlist) defining the specific characters and format allowed. All input should be neutralized, not just parameters that the user is supposed to specify, but all data in the request, including hidden fields, cookies, headers, the URL itself, and so forth. A common mistake that leads to continuing XSS vulnerabilities is to validate only fields that are expected to be redisplayed by the site. We often encounter data from the request that is reflected by the application server or the application that the development team did not anticipate. Also, a field that is not currently reflected may be used by a future developer. Therefore, validating ALL parts of the HTTP request is recommended.
Mitigation MIT-30.1
Strategy: Output Encoding
- Use and specify an output encoding that can be handled by the downstream component that is reading the output. Common encodings include ISO-8859-1, UTF-7, and UTF-8. When an encoding is not specified, a downstream component may choose a different encoding, either by assuming a default encoding or automatically inferring which encoding is being used, which can be erroneous. When the encodings are inconsistent, the downstream component might treat some character or byte sequences as special, even if they are not special in the original encoding. Attackers might then be able to exploit this discrepancy and conduct injection attacks; they even might be able to bypass protection mechanisms that assume the original encoding is also being used by the downstream component.
- The problem of inconsistent output encodings often arises in web pages. If an encoding is not specified in an HTTP header, web browsers often guess about which encoding is being used. This can open up the browser to subtle XSS attacks.
Mitigation MIT-43
With Struts, write all data from form beans with the bean's filter attribute set to true.
Mitigation MIT-31
Strategy: Attack Surface Reduction
To help mitigate XSS attacks against the user's session cookie, set the session cookie to be HttpOnly. In browsers that support the HttpOnly feature (such as more recent versions of Internet Explorer and Firefox), this attribute can prevent the user's session cookie from being accessible to malicious client-side scripts that use document.cookie. This is not a complete solution, since HttpOnly is not supported by all browsers. More importantly, XmlHttpRequest and other powerful browser technologies provide read access to HTTP headers, including the Set-Cookie header in which the HttpOnly flag is set.
CAPEC-18: XSS Targeting Non-Script Elements
This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an adversary to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote adversary to collect and interpret the output of said attack.
CAPEC-193: PHP Remote File Inclusion
In this pattern the adversary is able to load and execute arbitrary code remotely available from the application. This is usually accomplished through an insecurely configured PHP runtime environment and an improperly sanitized "include" or "require" call, which the user can then control to point to any web-accessible file. This allows adversaries to hijack the targeted application and force it to execute their own instructions.
CAPEC-32: XSS Through HTTP Query Strings
An adversary embeds malicious script code in the parameters of an HTTP query string and convinces a victim to submit the HTTP request that contains the query string to a vulnerable web application. The web application then procedes to use the values parameters without properly validation them first and generates the HTML code that will be executed by the victim's browser.
CAPEC-86: XSS Through HTTP Headers
An adversary exploits web applications that generate web content, such as links in a HTML page, based on unvalidated or improperly validated data submitted by other actors. XSS in HTTP Headers attacks target the HTTP headers which are hidden from most users and may not be validated by web applications.
