Arc Search: User Interface (UI) Misrepresentation of Critical Information

Published Updated By the CyberSecBulletin desk

CVE-2026-94183 is a high-severity user interface (UI) misrepresentation of critical information vulnerability in Arc Search from The Browser Company of New York, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 1.12.10 as the first without the flaw, so updating Arc Search to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Arc Search to 1.12.10 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Arc Search for Android before version 1.12.10 does not display a fullscreen notification when a page enters fullscreen mode while the app is running in the background. A remote attacker can exploit this via a specially crafted website to render fake UI elements, such as a spoofed address bar, misleading the user about the origin of displayed content and increasing the risk of phishing.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: User Interface (UI) Misrepresentation of Critical Information

The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.

How developers prevent this class of flaw

  • Perform data validation (e.g. syntax, length, etc.) before interpreting the data.
  • Create a strategy for presenting information, and plan for how to display unusual characters.
