Answer in brief
CVE-2026-81852 records a Low severity (CVSS 2.1) vulnerability in AshAdmin ships a hardcoded CSP nonce, allowing nonce-based CSP bypass. The current sources do not mark it as known exploited. The current feed maps ash-project/ash_admin (generic), ash-project/ash_admin (generic), ash-project/ash-project/ash_admin (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 2.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Use of Insufficiently Random Values vulnerability in ash-project ash_admin ships a hardcoded, publicly known CSP nonce, defeating nonce-based Content-Security-Policy protection. When mounted without :csp_nonce_assign_key, AshAdmin.Router.ash_admin/2 defaulted the img, style, and script nonces to the literal constant ash_admin-Ed55GFnX, which AshAdmin.Layouts wrote verbatim into the nonce attribute of its inline <style> and <script> tags on every response. The value is a compile-time constant published in the repository and is never rotated per request. If an application's CSP script-src allow-lists that documented default, any HTML-injection sink on an admin page can reuse the known nonce to run inline scripts the policy was meant to block. The fix generates a fresh random nonce per request. This issue affects ash_admin: from 0.10.8 before 1.3.1.
