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: None: There is no loss of confidentiality within 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 25 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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 Material Icons and drupal/material_icons to 2.0.4.

AI-suggested

To mitigate CVE-2026-3210, organizations should immediately identify Drupal installations using the Material Icons module and verify the version in use. Upgrading the module to version 2.0.4 or later, once released, is the most effective remediation. If you cannot patch yet, organizations should restrict access to the affected module's resources by implementing strict web server access controls or Drupal permission configurations to prevent unauthorized browsing. Conduct thorough audits of user roles and permissions to ensure least privilege principles are enforced. Employ web application firewalls (WAFs) to detect and block suspicious forceful browsing attempts targeting the module's endpoints. Additionally, implement comprehensive logging and alerting to detect anomalous access patterns indicative of exploitation attempts. Regularly review and update Drupal core and contributed modules to minimize exposure to known vulnerabilities. Consider isolating critical Drupal instances behind VPNs or IP whitelisting where feasible to reduce attack surface.

Description

Incorrect Authorization vulnerability in Drupal Material Icons allows Forceful Browsing.This issue affects Material Icons: from 0.0.0 before 2.0.4.

Impact

The impact of CVE-2026-3210 is significant for organizations using Drupal with the vulnerable Material Icons module. Unauthorized access through forceful browsing can lead to exposure of sensitive data or unauthorized modification of site content or settings. This can undermine the confidentiality and integrity of web applications, potentially damaging organizational reputation and trust. Attackers could leverage this vulnerability to gain footholds in web infrastructure, facilitating further attacks such as privilege escalation or data exfiltration. For e-commerce, government, healthcare, and other sectors relying on Drupal, this could result in compliance violations and financial losses. The absence of known exploits currently reduces immediate risk but does not diminish the urgency for remediation, as public disclosure often leads to rapid development of exploit code. The vulnerability's ease of exploitation, without requiring user interaction, increases the threat level. The scope of affected systems is broad due to Drupal's global adoption, especially in enterprise and public sector websites. Failure to address this vulnerability promptly could lead to widespread exploitation and significant operational disruptions.

CWE-863Incorrect Authorization (opens in a new tab)
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.
