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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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

Disclosed: evidence found.
CVE published 27 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.
CVSS exploit maturity: proof of concept public
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

Apply the official patch released by givanz identified by commit b0fa7ff74a3539c6d37000db152caad572e4c39b immediately to all affected Vvveb installations.
If patching is temporarily not possible, restrict network access to the Vvveb Code Editor component by implementing firewall rules or network segmentation to limit exposure to trusted users only.
Conduct a thorough audit of server file permissions to ensure that sensitive files are not accessible by the web server user beyond what is necessary.
Implement web application firewalls (WAF) with custom rules to detect and block path traversal patterns in HTTP requests targeting the vulnerable endpoint.
Monitor logs for suspicious file path requests or unusual access patterns that may indicate exploitation attempts.
Educate development and operations teams about secure input validation and sanitization practices to prevent similar vulnerabilities in future code.
Regularly update and patch all components of the web application stack to minimize exposure to known vulnerabilities.

Description

A weakness has been identified in givanz Vvveb up to 1.0.7.3. This issue affects the function sanitizeFileName of the file system/functions.php of the component Code Editor. Executing a manipulation of the argument File can lead to path traversal. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. This patch is called b0fa7ff74a3539c6d37000db152caad572e4c39b. Applying a patch is advised to resolve this issue.

Impact

The primary impact of CVE-2025-12203 is unauthorized access to files on the affected server due to path traversal. This can lead to disclosure of sensitive data such as configuration files, source code, credentials, or other protected information. While the vulnerability does not directly allow code execution or system takeover, the information gained can facilitate further attacks, including privilege escalation or lateral movement within a network. The ease of remote exploitation without authentication increases the threat level, especially for internet-facing deployments of Vvveb. Organizations relying on Vvveb for web editing or content management may face data breaches or operational disruptions if attackers leverage this vulnerability. The medium severity rating reflects the moderate risk posed by this vulnerability, balancing the limited impact with the ease of exploitation and potential for information disclosure.
