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: 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 8 Dec 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 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 enalean/tuleap to 17.0.99.1762431347.

AI-suggested

Immediate upgrade to the fixed Tuleap versions: Community Edition 17.0.99.1762431347 or Enterprise Edition 17.0-2, 16.13-7, or 16.12-10.
Conduct an audit of current user privileges and project access controls to ensure the principle of least privilege is enforced, minimizing the risk of low-privilege accounts being exploited.
Implement network segmentation and access restrictions to limit Tuleap server exposure to trusted internal networks and VPNs only.
Monitor Tuleap logs and access patterns for unusual activity, such as unauthorized attempts to access project files or release information.
Educate users and administrators about the risks of privilege misuse and encourage strong authentication practices, including multi-factor authentication where possible.
Review and update incident response plans to include scenarios involving unauthorized data disclosure from collaboration platforms.
If upgrading immediately is not feasible, consider temporary compensating controls such as disabling file release system features or restricting access to sensitive projects until patches can be applied.

Description

Tuleap is an Open Source Suite for management of software development and collaboration. Versions below 17.0.99.1762431347 of Tuleap Community Edition and Tuleap Enterprise Edition below 17.0-2, 16.13-7 and 16.12-10 allow attackers to access file release system information in projects they do not have access to. This issue is fixed in version 17.0.99.1762431347 of the Tuleap Community Edition and versions 17.0-2, 16.13-7 and 16.12-10 of Tuleap Enterprise Edition.

Impact

For European organizations, the primary impact of CVE-2025-64497 is the unauthorized disclosure of sensitive project and release information managed within Tuleap. This can lead to intellectual property theft, exposure of confidential development plans, and potential competitive disadvantages. Organizations in sectors such as software development, technology, finance, and government that rely on Tuleap for project management and collaboration are particularly vulnerable. The breach of confidentiality could also lead to compliance issues under regulations like GDPR if personal data or sensitive business information is exposed. While the vulnerability does not affect system integrity or availability, the leakage of sensitive information can undermine trust and damage reputations. Since exploitation requires only low privileges and network access, insider threats or compromised user accounts could be leveraged to exploit this flaw. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for targeted attacks, especially in high-value environments.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #24OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Architecture and Design · Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
