CVE-2026-58836
HighCVSS 7.8Summary
In handlePackagePostInstall of InstallPackageHelper.java, there is a possible Enhanced Confirmation Mode (ECM) bypass vulnerability that allows a sideloaded application to modify the package source during a self-update due to a logic error in the code. This could lead to local escalation of privilege with User execution privileges needed.
Risk Assessment
An attacker could bypass the package installation confirmation mechanism, enabling installation of malicious software and privilege escalation.
Recommendation
Update the system to the latest vendor-patched version. Avoid installing applications from unknown sources.
