Which packages are affected by GHSA-3r7j-8mqh-6qhx?

GHSA-3r7j-8mqh-6qhx affects the following packages: io.github.skylot:jadx-plugins-api (Maven). Ecosystems affected: Maven.

How do I fix GHSA-3r7j-8mqh-6qhx?

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 GHSA-3r7j-8mqh-6qhx is resolved across your whole dependency graph.

How do I detect GHSA-3r7j-8mqh-6qhx in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.github.skylot:jadx-plugins-api. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-3r7j-8mqh-6qhx if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against GHSA-3r7j-8mqh-6qhx?

O3 pinpoints whether GHSA-3r7j-8mqh-6qhx is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-3r7j-8mqh-6qhx actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-3r7j-8mqh-6qhx, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-3r7j-8mqh-6qhx?

GHSA-3r7j-8mqh-6qhx has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 23th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-3r7j-8mqh-6qhx?

GHSA-3r7j-8mqh-6qhx is classified as Improper Input Validation (CWE-20). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-3r7j-8mqh-6qhx published, and has it been updated?

GHSA-3r7j-8mqh-6qhx was published on October 20, 2022 and was last updated on December 1, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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.
	at java.desktop/javax.swing.text.html.HTMLEditorKit$HTMLFactory.create(HTMLEditorKit.java:1387)

	at java.desktop/javax.swing.text.CompositeView.loadChildren(CompositeView.java:112)

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);
