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: 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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
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 impacted component 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 impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 30 May 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 2026-10-25.

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

1. Immediate upgrade to valtimo-backend-libraries version 12.13.0.RELEASE or later, where the vulnerability is patched. 2. If upgrading is not immediately feasible, implement the recommended workaround by overriding the endpoint security configurations in ObjectenApiHttpSecurityConfigurer and ObjectManagementHttpSecurityConfigurer to enforce strict authorization checks. Careful testing is required to ensure that this does not impair critical functionality. 3. Conduct a thorough audit of exposed object URLs and restrict their exposure through other channels (e.g., logs, APIs, or third-party integrations) to prevent unauthorized access. 4. Implement network-level access controls such as IP whitelisting and segmentation to limit access to the valtimo backend services. 5. Monitor logs and alerts for unusual activity related to object management endpoints, including unexpected listing, viewing, or modification attempts. 6. Educate development and operations teams about secure configuration practices to prevent similar authorization misconfigurations in the future. 7. Review and tighten role-based access controls (RBAC) within the platform to minimize privileges granted to users and services.

Description

Valtimo is a platform for Business Process Automation. In versions starting from 11.0.0.RELEASE to 11.3.3.RELEASE and 12.0.0.RELEASE to 12.12.0.RELEASE, all objects for which an object-management configuration exists can be listed, viewed, edited, created or deleted by unauthorised users. If object-urls are exposed via other channels, the contents of these objects can be viewed independent of object-management configurations. This issue has been patched in version 12.13.0.RELEASE. A workaround for this issue involves overriding the endpoint security as defined in ObjectenApiHttpSecurityConfigurer and ObjectManagementHttpSecurityConfigurer. Depending on the implementation, this could result in loss of functionality.

Impact

For European organizations using the valtimo-platform for business process automation, this vulnerability poses a significant risk. Unauthorized access to business process objects can lead to exposure of sensitive corporate data, unauthorized modifications that disrupt business workflows, and potential data integrity issues. Given the critical role of business process automation in operational efficiency, exploitation could result in operational disruptions, compliance violations (especially under GDPR if personal data is involved), and reputational damage. The ability to create or delete objects without authorization further increases the risk of sabotage or data loss. Since the vulnerability can be exploited remotely with low complexity, attackers could leverage it to gain broader access within the affected environment. Organizations in sectors such as finance, manufacturing, government, and healthcare that rely heavily on automated business processes are particularly at risk.

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.
