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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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 impacted component.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 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.

What to do

Upgrade Drupal Mini site to 3.0.2.

AI-suggested

European organizations should immediately inventory their Drupal Mini site installations to identify affected versions prior to 3.0.2. Until an official patch or upgrade is applied, restrict privileges associated with the vulnerable actions to the minimum necessary users and roles, applying the principle of least privilege. Implement Web Application Firewalls (WAF) with rules to detect and block common XSS payloads targeting Drupal endpoints. Conduct thorough code reviews and input validation enhancements to sanitize user inputs and outputs within the Mini site module. Monitor logs for unusual activity indicative of stored XSS exploitation attempts, such as unexpected script injections or anomalous user behavior. Educate administrators and developers about the risks of unsafe privilege assignments and encourage prompt application of security updates once available. Additionally, consider deploying Content Security Policy (CSP) headers to mitigate the impact of injected scripts. Regularly back up Drupal site data and configurations to enable rapid recovery if an attack occurs. Finally, coordinate with Drupal community channels to stay informed about patches and advisories related to this vulnerability.

Description

CVE-2025-13979 is a medium severity vulnerability in the Drupal Mini site module versions before 3.0.2. It involves a privilege defined with unsafe actions (CWE-267) that allows an authenticated user with certain privileges to perform stored Cross-Site Scripting (XSS) attacks without requiring user interaction. The vulnerability impacts confidentiality and integrity but does not affect availability. Exploitation requires network access and low complexity with privileges, but no user interaction. There are no known exploits in the wild yet, and no patches have been linked. European organizations using affected Drupal Mini site versions should prioritize updating to mitigate risks, especially those with web-facing Drupal installations. Countries with higher Drupal adoption and critical infrastructure relying on Drupal are more likely to be impacted.

Impact

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive information and compromise of user accounts through stored XSS attacks. Attackers exploiting this flaw could execute malicious scripts in the context of other users, potentially stealing session tokens, redirecting users to malicious sites, or performing actions on behalf of legitimate users. This undermines the confidentiality and integrity of data managed by Drupal Mini site installations. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that use Drupal-based web portals are at higher risk due to the sensitive nature of their data and the potential reputational damage from a successful attack. The medium severity rating indicates that while the vulnerability is not critical, it still requires timely remediation to prevent exploitation. Since exploitation requires authenticated privileges, insider threats or compromised accounts could be leveraged to exploit this vulnerability. The absence of user interaction lowers the barrier for exploitation once privileges are obtained. Overall, the impact includes potential data breaches, loss of user trust, and increased risk of further attacks leveraging the initial XSS foothold.

CWE-267Privilege Defined With Unsafe Actions (opens in a new tab)
Base weakness
A particular privilege, role, capability, or right can be used to perform unsafe actions that were not intended, even when it is assigned to the correct entity.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Operation · Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment.
