CVE-2022-20338

Status: ModifiedLow (3.3)—💥 PoC

In HierarchicalUri.readFrom of Uri.java, there is a possible way to craft a malformed Uri object due to improper input validation. This could lead to a local escalation of privilege, preventing processes from validating URIs correctly, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11 Android-12 Android-12LAndroid ID: A-171966843

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
