EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.0 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 90% 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).

jadx is a Dex to Java decompiler. Prior to 1.5.6, jadx-gui is affected by an HTML injection vulnerability in the Summary tab because SummaryNode.java appends arches and perArchCount values derived from .so file path components inside an APK into an HTML panel without escaping. A malicious APK with an HTML URL-encoded ZIP entry name can force rendering of arbitrary HTML, perform out-of-band requests, disclose the victim IP address, or interact with locally exposed applications. This issue is fixed in version 1.5.6.
