CVE-2025-10827 Overview
CVE-2025-10827 is a reflected cross-site scripting (XSS) vulnerability in PHPJabbers Restaurant Menu Maker versions up to 1.1. The flaw resides in /preview.php, where the theme parameter is rendered without proper output encoding. Remote attackers can craft URLs containing malicious JavaScript that executes in a victim's browser when the link is opened. The issue is tracked under [CWE-79] and public exploit details have been published. The vulnerability affects a commercial PHP application used by restaurants to build and display digital menus.
Critical Impact
Attackers can execute arbitrary JavaScript in the context of the victim's browser session, enabling session theft, credential harvesting, and defacement of the menu preview page.
Affected Products
- PHPJabbers Restaurant Menu Maker versions up to and including 1.1
- Deployments exposing /preview.php to untrusted clients
- Instances where administrators or customers follow attacker-supplied preview URLs

Technical Details for CVE-2025-10827
Vulnerability Analysis
The vulnerability is a reflected cross-site scripting flaw in the preview.php endpoint of PHPJabbers Restaurant Menu Maker. The application accepts a theme argument from the HTTP request and reflects that value into the rendered HTML response without sanitization or contextual encoding. An attacker crafts a URL that embeds a JavaScript payload inside theme and delivers the link through phishing, chat, or a third-party site. When the victim opens the link, the browser executes the payload under the origin of the vulnerable application.
User interaction is required because the payload only fires after the victim loads the attacker-controlled URL. The confidentiality impact is limited, but attackers can still hijack authenticated sessions, exfiltrate cookies, and manipulate page content. Because the endpoint appears intended for public menu previews, exploitation does not require prior authentication.
Root Cause
The root cause is missing output encoding on the theme request parameter. preview.php inserts the parameter value directly into the HTML response, allowing HTML and script tokens supplied by the client to alter document structure. The application does not enforce an allow-list of valid theme identifiers and does not apply context-appropriate escaping.
Attack Vector
Exploitation is remote and requires only that a target user click a crafted link. A public writeup describing the injection point is available on the GitHub CVE Issue, and vulnerability metadata is tracked in the VulDB entry #325184.
The vulnerability manifests in the theme query parameter handler within /preview.php. Rather than treating the parameter as an identifier and validating it against a set of known themes, the code interpolates the attacker-controlled string into the HTML sent to the browser. Any script tags or event-handler attributes contained in the input become part of the parsed document.
Detection Methods for CVE-2025-10827
Indicators of Compromise
- HTTP requests to /preview.php containing script tokens, angle brackets, or event handler names in the theme parameter
- Web server access logs showing unusually long or URL-encoded theme values referencing javascript:, onerror=, or <script>
- Referrer headers pointing to unknown external domains that redirect users into preview.php
Detection Strategies
- Inspect web application firewall logs for reflected XSS signatures targeting the theme parameter of preview.php
- Correlate outbound browser traffic from administrative sessions that immediately follows access to a crafted preview URL
- Deploy Content Security Policy (CSP) reporting to capture blocked inline script execution attempts originating from the application
Monitoring Recommendations
- Alert on any preview.php request whose theme value contains characters outside a strict alphanumeric allow-list
- Monitor authenticated administrator sessions for anomalous cookie access or session token reuse from new IP addresses
- Track click-through patterns from external referrers to /preview.php and flag spikes indicative of phishing campaigns
How to Mitigate CVE-2025-10827
Immediate Actions Required
- Restrict public access to /preview.php behind authentication or IP allow-listing until a vendor patch is applied
- Deploy a WAF rule that blocks requests where the theme parameter contains HTML metacharacters such as <, >, ", or '
- Instruct administrators and staff to avoid clicking preview links delivered through email or messaging platforms
Patch Information
No vendor advisory or patched release has been published in the referenced sources at the time of writing. Track the VulDB CTI Report #325184 and the PHPJabbers product page for updates. Until a fixed version is released, treat all instances of Restaurant Menu Maker 1.1 and earlier as vulnerable.
Workarounds
- Implement a reverse-proxy filter that rewrites or drops requests carrying non-alphanumeric characters in the theme parameter
- Add a strict Content-Security-Policy header disallowing inline scripts and untrusted script sources to contain payload execution
- Enable HttpOnly and Secure flags on session cookies to reduce the impact of cookie theft through injected scripts
- Replace preview.php output rendering with server-side templating that HTML-encodes all request-derived values
