CVE-2026-87492 is a high-severity incorrect-authorization vulnerability in Google Chrome DevTools prior to version 153.0.8010.36. A remote attacker can use a crafted HTML page to trigger insufficient authorization in DevTools and potentially execute arbitrary code outside the browser sandbox.

This is a 100-file JavaScript/HTML proof-of-concept repository centered on a patched Chromium build with the experimental MojoJS Blink feature enabled. Most files under gen/ are auto-generated Chromium Mojo bindings; downloads.mjs supplies a generated-style binding for the Downloads WebUI PageHandler, and BufferHolder.js is a generic binary serialization helper. The meaningful exploit-stage code is bundled_2.js, which reads the first entry from the privileged downloads-manager element and calls its internal PageHandler.drag() method with that download's identifier. bop.html fetches a missing bundled_payload.js and sends a wildcard-origin postMessage to a nested opener frame, apparently providing cross-window orchestration. cdp_callback.html contains an incomplete Chrome DevTools Protocol callback scaffold and does not implement commands. The README identifies the project as an SI-bypass PoC and requires a specific Chromium source revision, a renderer patch, MojoJS enablement, and localhost/cross-site hosting on port 3020. The absent server script, patch, primary page, and bundled payload mean the provided snapshot cannot independently demonstrate the claimed full bypass.
