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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
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

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 2026-10-25.

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.

AI-suggested

European organizations should immediately identify any deployments of givanz Vvveb versions 1.0.7.0 through 1.0.7.2, particularly those exposing SVG file handling functionality to end users or external inputs. The primary mitigation is to upgrade to the vendor's patched version once released. Until then, organizations should implement strict input validation and sanitization on SVG files, disallowing or filtering potentially malicious scripts or embedded content. Employ Content Security Policy (CSP) headers to restrict script execution contexts and reduce the impact of XSS attacks. Additionally, disable or restrict SVG file uploads or processing where feasible. User awareness training to recognize phishing attempts that might exploit this vulnerability is recommended. Monitoring web application logs for unusual activity related to SVG handling can help detect exploitation attempts. Finally, conduct regular security assessments and penetration tests focusing on SVG and file upload features to identify residual risks.

Description

A vulnerability was identified in givanz Vvveb up to 1.0.7.2. Affected by this issue is some unknown functionality of the component SVG File Handler. Such manipulation leads to cross site scripting. The attack may be launched remotely. The exploit is publicly available and might be used. Once again the project maintainer reacted very professional: "I accept the existence of these vulnerabilities. (...) I fixed the code to remove these vulnerabilities and will push the code to github and make a new release."

Impact

For European organizations, this vulnerability poses a moderate risk, especially for those using the affected versions of givanz Vvveb in web development or content management workflows involving SVG files. Exploitation could lead to theft of user credentials, session tokens, or unauthorized actions performed on behalf of users, potentially compromising sensitive data or internal systems. Organizations in sectors with high web presence such as e-commerce, media, and government services could face reputational damage and regulatory scrutiny if user data is compromised. The requirement for user interaction reduces the likelihood of widespread automated exploitation but targeted phishing or social engineering campaigns could leverage this vulnerability. Since the exploit is publicly available, opportunistic attackers might attempt to exploit unpatched systems. The vulnerability's medium severity suggests it should be prioritized but is not critical. However, failure to patch could lead to chained attacks or serve as an entry point for more severe compromises.

Summary

CVE-2025-11027 is a cross-site scripting (XSS) vulnerability affecting the givanz Vvveb product, specifically versions 1.0.7.0 through 1.0.7.2. The vulnerability resides in an unspecified functionality within the SVG File Handler component. This flaw allows an attacker to inject malicious scripts that can be executed in the context of a victim's browser session when interacting with the vulnerable component. The attack can be launched remotely without requiring authentication, but it does require user interaction (e.g., the victim must visit a crafted page or interact with malicious SVG content). The vulnerability has a CVSS 4.8 (medium) score, reflecting moderate impact and exploitability. The vendor has acknowledged the issue and committed to releasing a patched version. No known exploits are currently observed in the wild, but public exploit code is available, increasing the risk of exploitation. The vulnerability impacts confidentiality and integrity to a limited extent by enabling script execution, potentially leading to session hijacking, defacement, or other client-side attacks. Availability impact is negligible. The vulnerability does not require elevated privileges but does require user interaction, which somewhat limits the attack surface. The SVG File Handler component's role in processing SVG files suggests that any feature allowing user-uploaded or externally sourced SVG content could be an attack vector. Given the nature of XSS, the vulnerability primarily threatens web applications or services that embed or process SVG content using the affected versions of Vvveb.
