# CVE-2026-103922: Capacitor Android and iOS: remote content can be loaded at the app origin via the internal HTTP proxy path

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.2% , percentile 11: FIRST’s model estimates a 0.2% chance of exploitation activity in the next 30 days, higher than 11% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes @capacitor/android (npm) >= 6.0.0, < 6.2.2, fixed in 6.2.2 ; @capacitor/android (npm) >= 7.0.0, < 7.6.9, fixed in 7.6.9 ; @capacitor/ios (npm) >= 6.0.0, < 6.2.2, fixed in 6.2.2 ; @capacitor/ios (npm) >= 7.0.0, < 7.6.9, fixed in 7.6.9 . Check your lockfile, including transitive dependencies.

## What it is

Capacitor is a cross-platform native runtime for web applications. From 6.0.0 until 6.2.2, 7.6.9, 8.3.5, 8.4.3, and 8.5.1, the Android and iOS WebView navigation guard validates a target URL's host and scheme but not its path, allowing a victim who activates an untrusted link to navigate a frame to /capacitorhttpinterceptor. The native proxy can fetch an attacker-selected URL and return the response as a document at the application's own origin, allowing script in that response to access same-origin storage, cookies, and registered Capacitor plugin capabilities. Applications remain affected when CapacitorHttp is disabled because affected releases serve the proxy path regardless of that setting. This issue is fixed in versions 6.2.2, 7.6.9, 8.3.5, 8.4.3, and 8.5.1.
