CVE-2026-5457 Details
Description
A security flaw has been discovered in PropertyGuru AgentNet Singapore App up to 23.7.10 on Android. This affects an unknown function of the file com/allproperty/android/agentnet/BuildConfig.java of the component com.allproperty.android.agentnet. The manipulation of the argument SEGMENT_ANDROID_WRITE_KEY/SEGMENT_TOS_WRITE_KEY results in use of hard-coded cryptographic key . The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in the PropertyGuru AgentNet Singapore App for Android, in versions prior to 23.7.10. The issue arises from hard-coded Segment write keys found in the BuildConfig.java file of the com.allproperty.android.agentnet component. This vulnerability allows local attackers to extract the keys through reverse engineering and use them to send arbitrary tracking events or modify user profiles via Segment's API. Such exploitation could inject fraudulent analytics data, corrupt business intelligence, disrupt user segmentation, and misuse downstream systems that rely on this data.
