Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Exploited in the wildExploited: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Organizations should immediately implement strict input validation and output encoding on the 'selected_date' parameter to prevent script injection. Employing a web application firewall (WAF) with custom rules to detect and block XSS payloads targeting this parameter can provide an effective interim defense. Regularly monitor web server logs and application behavior for signs of exploitation attempts or anomalous activity related to reservation inputs. If possible, isolate the reservation system from other critical infrastructure to limit lateral movement in case of compromise. Educate users and staff about phishing risks associated with XSS attacks to reduce the likelihood of successful social engineering. Engage in active threat intelligence sharing to stay informed about emerging exploits targeting this vulnerability. Finally, consider migrating to alternative, well-maintained reservation platforms if vendor support remains absent and patches are not forthcoming.

Description

A vulnerability was determined in jairiidriss RestaurantWebsite up to e7911f12d035e8e2f9a75e7a28b59e4ef5c1d654. Impacted is an unknown function of the component Make a Reservation. This manipulation of the argument selected_date causes cross site scripting. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, this vulnerability poses a risk primarily to those operating or managing online restaurant reservation platforms using the jairiidriss RestaurantWebsite or similar software. Successful exploitation could compromise user session data, enabling attackers to impersonate users or steal sensitive information such as personal details or reservation data. This can lead to reputational damage, loss of customer trust, and potential regulatory consequences under GDPR if personal data is compromised. Additionally, attackers could use the vulnerability to deliver phishing payloads or malware, increasing the risk of broader network compromise. The hospitality sector in Europe is significant, and many restaurants rely on online booking systems, making this vulnerability a potential vector for targeted attacks. The continuous delivery model and lack of vendor patching complicate timely remediation, increasing exposure duration. Organizations may also face indirect impacts such as increased support costs and customer dissatisfaction due to exploitation consequences.

Summary

CVE-2025-13802 identifies a cross-site scripting (XSS) vulnerability in the jairiidriss RestaurantWebsite, specifically within the 'Make a Reservation' feature. The vulnerability is caused by insufficient input validation and output encoding of the 'selected_date' parameter, which can be manipulated by remote attackers to inject malicious JavaScript code. This flaw allows attackers to execute scripts in the context of the victim's browser, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The vulnerability does not require authentication and can be exploited remotely, but user interaction is necessary to trigger the malicious payload. The product follows a continuous delivery model with rolling releases, complicating version tracking and patch management. The vendor has not responded to early notifications, and no patches or updated releases are currently available. The CVSS 4.0 base score is 5.3 (medium), reflecting the network attack vector, low complexity, no privileges required, but requiring user interaction and causing limited integrity impact. No known exploits are currently in the wild, but public disclosure increases the risk of exploitation attempts. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls.
