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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: None: There is no loss of integrity within 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 2026-10-26.

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

Upgrade Drupal Entity Share to 3.13.0.

AI-suggested

1. Upgrade the Drupal Entity Share module to version 3.13.0 or later as soon as the patch is released to address the authorization flaw. 2. If you cannot patch yet, implement strict access control policies at the web server or application firewall level to restrict access to sensitive entity sharing endpoints. 3. Review and tighten Drupal user permissions related to entity sharing to minimize exposure. 4. Monitor web server and Drupal logs for unusual or unauthorized access attempts indicative of forceful browsing. 5. Employ network segmentation and limit public exposure of Drupal instances that handle sensitive data. 6. Conduct regular security audits and penetration testing focusing on authorization controls within Drupal modules. 7. Educate administrators and developers about the risks of incorrect authorization and best practices for secure module configuration. 8. Subscribe to Drupal security advisories and CVE databases to stay informed about patch releases and emerging threats related to this vulnerability.

Description

CVE-2025-13985 is an incorrect authorization vulnerability in the Drupal Entity Share module versions before 3.13.0. It allows unauthenticated attackers to perform forceful browsing, potentially accessing resources they should not be authorized to view. The vulnerability has a CVSS score of 5.3, indicating medium severity, with low impact on confidentiality and no impact on integrity or availability. Exploitation requires no privileges or user interaction and can be performed remotely. No known exploits are currently reported in the wild. European organizations using Drupal with the vulnerable Entity Share module should prioritize patching or mitigating this issue to prevent unauthorized data exposure. Countries with high Drupal adoption and critical public or private sector infrastructures using Drupal are more likely to be affected.

Impact

For European organizations, this vulnerability poses a risk of unauthorized data exposure through forceful browsing of shared entities in Drupal sites using the vulnerable Entity Share module. Confidentiality of sensitive information could be compromised, especially in sectors such as government, healthcare, finance, and education, where Drupal is widely used for content management. Although the impact on integrity and availability is negligible, unauthorized access to data can lead to privacy violations, regulatory non-compliance (e.g., GDPR), and reputational damage. Attackers can exploit this vulnerability remotely without authentication, increasing the risk of widespread scanning and data leakage. Organizations with public-facing Drupal sites or interlinked Drupal instances sharing sensitive entities are particularly at risk. The lack of known exploits in the wild currently reduces immediate threat but does not eliminate the risk of future exploitation once exploit code becomes available.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #17OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
