Broadcast Receiver Public Access Enables Unauthorized Admin Operations

Unchecked public access permissions on a core Broadcast Receiver allow unauthorized local software components to invoke administrative operations.

Casky was already ahead

This CVE exploits attack patterns that Casky's 203matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-49189 exposes a critical privilege escalation vulnerability in Android applications where Broadcast Receivers—components designed to receive system-wide messages—lack proper permission checks and are publicly accessible. This allows any local application on a device to invoke administrative operations without authorization, effectively bypassing intended access controls. Organizations deploying applications built on vulnerable frameworks are at risk, particularly in enterprise environments where multiple apps coexist on shared devices. The CVSS score of 7.8 reflects the high impact: attackers gain local privilege escalation to perform sensitive administrative functions, potentially compromising data integrity, system configuration, and operational security.

Casky's 203 mapped security skills leverage Claude AI's extended reasoning to identify the attack chain behind this vulnerability across MITRE ATT&CK Privilege Escalation techniques (TA0004). Practitioners using Casky would detect suspicious patterns including: unexpected inter-process communication (IPC) calls to Broadcast Receivers without credential validation, unauthorized invocations of administrative intents, and permission model violations in component declarations. The platform's skills enable detection of both the misconfiguration (overly permissive intent filters) and exploitation attempts (local processes triggering admin operations). Security teams gain visibility into which components lack proper export controls, how threat actors enumerate accessible receivers, and real-time identification of privilege escalation attempts—transforming static code analysis into dynamic threat detection across their application ecosystem.
