Description
Impact
Using jadx-gui to open a special zip file with entry containing HTML sequence like <html><frame> will cause interface to get stuck and throw exceptions like:
java.lang.RuntimeException: Can't build aframeset, BranchElement(frameset) 1,3
:no ROWS or COLS defined.

Guideline 3-7 / INJECT-7: Disable HTML display in Swing components:
Many Swing pluggable look-and-feels interpret text in certain components starting with <html> as HTML. If the text is from an untrusted source, an adversary may craft the HTML such that other components appear to be present or to perform inclusion attacks.
To disable the HTML render feature, set the "html.disable" client property of each component to Boolean.TRUE (no other Boolean true instance will do).
label.putClientProperty("html.disable", true);

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.github.skylot:jadx-plugins-api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update io.github.skylot:jadx-plugins-api to 1.4.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-39259 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
