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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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.

Exploitation evidence

CVE published 6 Nov 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.

What to do

Upgrade WeblateOrg weblate to 5.14.1.

AI-suggested

The primary mitigation is to upgrade Weblate installations to version 5.14.1 or later, where the vulnerability is fixed by removing IP addresses from audit logs accessible to invited users. Until upgrading is possible, organizations should restrict audit log access strictly to trusted users and avoid inviting untrusted or external users to projects with sensitive audit logs. Additionally, review and adjust Weblate’s audit log permissions and visibility settings to minimize exposure of sensitive information. Implement network segmentation and monitoring to detect unusual access patterns that might indicate reconnaissance attempts. Educate project administrators and users about the risks of sharing audit log information and encourage minimal sharing of invitations. Finally, ensure compliance with data protection policies by treating IP addresses as sensitive personal data and applying appropriate controls to their storage and dissemination.

Description

Weblate is a web based localization tool. In versions 5.14 and below, Weblate leaks the IP address of the project member inviting the user to the project in the audit log. The audit log includes IP addresses from admin-triggered actions, which can be viewed by invited users. This issue is fixed in version 5.14.1.

Impact

For European organizations using Weblate versions prior to 5.14.1, this vulnerability could lead to unintended disclosure of IP addresses of project members, including administrators or other privileged users. While the direct impact on system integrity or availability is negligible, the confidentiality breach could facilitate targeted reconnaissance or social engineering attacks by revealing network information. Organizations involved in software localization, particularly those managing sensitive or proprietary projects, may face privacy compliance risks under regulations like GDPR if IP addresses are considered personal data. The exposure could also undermine trust among collaborators if sensitive information is leaked to unintended parties. However, since exploitation requires user invitation and interaction, the scope of impact is limited to invited users and their potential misuse of the information. Overall, the impact is primarily a privacy concern with limited operational consequences but should not be ignored in environments with strict data protection requirements.

CWE-212Improper Removal of Sensitive Information Before Storage or Transfer (opens in a new tab)
Base weakness
The product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors.
Requirements
Clearly specify which information should be regarded as private or sensitive, and require that the product offers functionality that allows the user to cleanse the sensitive information from the resource before it is published or exported to other parties.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
Implementation · Operation · Attack Surface Reduction
Some tools can automatically analyze documents to redact, strip, or "sanitize" private information, although some human review might be necessary. Tools may vary in terms of which document formats can be processed.
