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: 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: 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: None: There is no impact to availability within the impacted component.

Detectable: 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 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

Immediate mitigation involves restricting the installation of untrusted or unknown applications on devices running GriceMobile com.grice.call 4.5.2. Organizations should implement mobile device management (MDM) policies to control app installations and monitor unusual call activity. Users and administrators should check for updates or patches from GriceMobile and apply them as soon as available. Developers and vendors must implement proper intent filtering and permission enforcement on sensitive components like MobileActivity to prevent unauthorized access. Additionally, monitoring telephony logs for unexpected call patterns can help detect exploitation attempts. Employing runtime application self-protection (RASP) or endpoint detection and response (EDR) solutions on mobile devices may provide further detection capabilities. Educating users about the risks of installing untrusted apps can reduce exposure.

Description

The GriceMobile com.grice.call application 4.5.2 for Android enables any installed application (with no permissions) to place phone calls without user interaction by sending a crafted intent via the com.iui.mobile.presentation.MobileActivity.

Impact

The vulnerability allows unauthorized applications to place phone calls silently, which can lead to several adverse impacts. Organizations may face financial losses due to toll fraud if attackers place premium-rate or international calls. Privacy is compromised as calls could be made without user knowledge, potentially leaking sensitive information or enabling stalking and harassment. The integrity of the device's telephony functions is undermined, reducing trust in the affected application and device security. Although availability is not impacted, the unauthorized call capability can disrupt normal phone usage and cause reputational damage. Enterprises relying on Android devices with this app installed may experience increased risk of insider threats or malware leveraging this flaw. The lack of required permissions and user interaction lowers the barrier for exploitation, increasing the threat surface significantly.

CWE-732Incorrect Permission Assignment for Critical Resource (opens in a new tab)
Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
Implementation
When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user), and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
Architecture and Design
Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly.
Architecture and Design · Operation · Sandbox or Jail
Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
