EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.3 under NVD CVSS v3. EPSS exploit probability: 2.3%, top 18% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

APKLeaks is an open-source project for scanning APK file for URIs, endpoints & secrets. APKLeaks prior to v2.0.3 allows remote attackers to execute arbitrary OS commands via package name inside application manifest. An attacker could include arguments that allow unintended commands or code to be executed, allow sensitive data to be read or modified or could cause other unintended behavior through malicious package name. The problem is fixed in version v2.0.6-dev and above.
