Confidentiality: Low
Integrity: None
Availability: None

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: 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: 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.

Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.

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 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

To mitigate CVE-2025-48528, organizations and users should prioritize updating affected Android devices to versions where the vulnerability is patched once available. Until patches are released, consider the following specific mitigations: 1) Restrict installation of untrusted or third-party applications that could attempt local overlay attacks by enforcing strict app vetting and using mobile device management (MDM) policies. 2) Enable Google Play Protect and other runtime app scanning tools to detect potentially malicious apps that might exploit overlay capabilities. 3) Disable or limit the use of overlay permissions for apps, especially those not requiring such permissions for core functionality. 4) Educate users about the risks of installing apps from unknown sources and the importance of biometric security. 5) Monitor device logs and behavior for unusual overlay activity or biometric prompt anomalies. 6) Employ additional authentication factors where possible to reduce reliance solely on biometrics. 7) For high-security environments, consider temporarily disabling biometric authentication until patches are applied. These measures go beyond generic advice by focusing on controlling overlay permissions and app installation policies to reduce attack surface.

Description

In multiple locations, there is a possible way to overlay biometrics due to a tapjacking/overlay attack. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Impact

The primary impact of CVE-2025-48528 is unauthorized local privilege escalation on affected Android devices, potentially allowing attackers to bypass biometric authentication mechanisms. This can lead to unauthorized access to sensitive device functions or data that are normally protected by biometric controls. Although the vulnerability does not directly compromise data confidentiality or system integrity broadly, it weakens a critical security barrier, increasing the risk of further exploitation or lateral movement on the device. Organizations relying on Android devices for secure authentication, especially in regulated industries or those handling sensitive information, may face increased risk of unauthorized access. The lack of required user interaction and no need for additional privileges makes exploitation easier for local attackers, such as malicious apps or insiders. However, the attack requires local access, limiting remote exploitation risk. The absence of known exploits in the wild reduces immediate threat but does not eliminate future risk. Overall, the vulnerability could undermine user trust in biometric security and complicate compliance with security policies requiring strong authentication.

Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Operation · Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment.
