Integrity: None
Availability: None

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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 29 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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 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.

AI-suggested

Immediate mitigation involves upgrading Acquia DAM to version 1.1.5 or later once the patch is released by Drupal/Acquia. Until a patch is available, organizations should implement strict network-level access controls to restrict access to the DAM system only to trusted internal users and IP ranges. Employ web application firewalls (WAF) with rules to detect and block forceful browsing attempts, such as unusual URL patterns or repeated unauthorized access attempts. Conduct thorough access log monitoring to identify suspicious browsing behavior indicative of exploitation attempts. Enforce strong authentication and authorization policies, including role-based access control (RBAC) and least privilege principles, to minimize exposure. Regularly audit user permissions and remove unnecessary access rights. Consider segmenting the DAM environment from public-facing networks to reduce attack surface. Finally, prepare incident response plans to quickly address any detected unauthorized access incidents.

Description

Missing Authorization vulnerability in Drupal Acquia DAM allows Forceful Browsing.This issue affects Acquia DAM: from 0.0.0 before 1.1.5.

Impact

For European organizations, the primary impact of CVE-2025-9954 is the unauthorized disclosure of sensitive digital assets managed within Acquia DAM. This can lead to intellectual property theft, exposure of confidential marketing materials, product designs, or customer data embedded in digital assets. Such data leakage can result in reputational damage, regulatory non-compliance (e.g., GDPR breaches if personal data is exposed), and financial losses. Since the vulnerability does not affect integrity or availability, the risk of data tampering or service disruption is low. However, the ease of exploitation without authentication or user interaction increases the likelihood of opportunistic attacks. Organizations in sectors heavily reliant on digital media, such as advertising, publishing, and e-commerce, face elevated risks. Additionally, the exposure of proprietary content can weaken competitive advantage and invite further targeted attacks. The lack of known exploits in the wild provides a window for proactive defense, but the high CVSS score demands urgent attention.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
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.
