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: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within 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), CVSS vector, 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 or the CVSS exploit maturity 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 prioritize updating givanz Vvveb to the forthcoming patched version once released by the vendor. Until then, they should implement strict network-level controls to limit access to the Vvveb service, such as IP whitelisting and firewall rules restricting inbound traffic to trusted sources. Monitoring and logging access to the Image Handler component can help detect suspicious activity indicative of exploitation attempts. Conducting an internal audit to identify all instances of the affected versions is critical to ensure comprehensive remediation. Additionally, organizations should review and minimize the sensitive information processed or stored by the Image Handler to reduce potential exposure. Employing web application firewalls (WAFs) with custom rules targeting known exploitation patterns may provide temporary protection. Finally, organizations should prepare incident response plans to address potential information disclosure incidents, including notification procedures aligned with GDPR requirements.

Description

A security flaw has been discovered in givanz Vvveb up to 1.0.7.2. This affects an unknown part of the component Image Handler. Performing manipulation results in information disclosure. Remote exploitation of the attack is possible. The exploit has been released to the public and may be exploited. 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 using givanz Vvveb versions 1.0.7.0 to 1.0.7.2, this vulnerability poses a risk of unauthorized information disclosure, which could compromise sensitive business or user data. The exposure of such information could aid attackers in crafting more targeted attacks, including phishing, social engineering, or exploitation of other vulnerabilities. While the vulnerability does not directly affect system integrity or availability, the confidentiality breach could lead to reputational damage, regulatory non-compliance (especially under GDPR), and potential financial losses. Organizations in sectors handling sensitive or personal data—such as finance, healthcare, and government—are particularly at risk. The remote exploitability without authentication means that attackers can attempt exploitation over the network, increasing the attack surface. The absence of known exploits in the wild currently limits immediate risk, but the public availability of exploit code raises the likelihood of future attacks.

Summary

CVE-2025-11028 is a medium-severity information disclosure vulnerability affecting the givanz Vvveb product, specifically versions 1.0.7.0 through 1.0.7.2. The flaw resides within the Image Handler component, where certain manipulations can lead to unauthorized exposure of sensitive information. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 base score is 6.9, reflecting a network attack vector with low complexity and no privileges or user interaction needed. The impact is limited to confidentiality, with no direct effect on integrity or availability. Public exploit code has been released, indicating that attackers could leverage this flaw to extract sensitive data from vulnerable systems. Given the nature of the flaw in an image handling component, the leaked information could include internal metadata, configuration details, or other sensitive content processed or stored by the component. This could facilitate further attacks or information gathering by adversaries.
