CVE-2026-10973: Uninitialized Use in Dawn in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to leak cross-origin data via a crafted HTML pag

Noroxi assessment

Priority: Monitor (action score 29/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.98% (FIRST EPSS); higher than 62.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Microsoft Edge (Chromium-based) 149.0.4022.52.

Low priority for now. Upgrade to Microsoft Edge (Chromium-based) 149.0.4022.52 or later.
