Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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.
Exploit Code Maturity: Unproven: No exploit code is available, or an exploit is theoretical.
Remediation Level: Official Fix: A complete vendor solution is available. Either the vendor has issued an official patch, or an upgrade is available.
Report Confidence: Confirmed: Detailed reports exist, or functional reproduction is possible (functional exploits may provide this). Source code is available to independently verify the assertions of the research, or the author or vendor of the affected code has confirmed the presence of the vulnerability.

Exploitation evidence

Disclosed: evidence found.
CVE published 14 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 2026-10-25.

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. Upgrade affected systems from Windows 10 Version 1507 (build 10.0.10240.0) to a supported and fully patched Windows 10 version or later to eliminate the vulnerability. 2. Restrict local access to sensitive systems by enforcing strict access controls and monitoring for unauthorized local logins. 3. Employ endpoint detection and response (EDR) solutions to detect suspicious local activity that could indicate exploitation attempts. 4. Limit the number of users with local privileges on affected systems to reduce the attack surface. 5. Monitor wireless network configurations and credentials for signs of compromise or unauthorized access. 6. Apply any future security updates from Microsoft addressing this vulnerability as soon as they become available. 7. Conduct regular vulnerability assessments and audits to identify legacy systems still running outdated OS versions. 8. Educate users and administrators about the risks of running unsupported OS versions and the importance of timely patching and upgrades.

Description

Out-of-bounds read in Windows WLAN Auto Config Service allows an authorized attacker to disclose information locally.

Impact

The primary impact of CVE-2025-55695 is the potential unauthorized disclosure of sensitive information on affected Windows 10 Version 1507 systems. This could include credentials, configuration data, or other memory-resident sensitive information related to wireless networking. While the vulnerability does not allow code execution or system compromise, the confidentiality breach could facilitate further attacks such as privilege escalation or lateral movement within a network. Organizations still operating legacy Windows 10 Version 1507 systems, especially in environments with sensitive wireless network configurations, face increased risk of data leakage. The requirement for local access limits remote exploitation, but insider threats or attackers with initial footholds could leverage this vulnerability. The lack of known exploits reduces immediate risk, but the vulnerability remains a concern for environments with outdated OS versions. Overall, the impact is medium severity due to confidentiality loss without direct integrity or availability effects.
