CVE-2026-82681
LowCVSS 2.0Summary
A vulnerability in ash_admin allows an attacker who controls a record's string primary key to rewrite the target of AshAdmin's row-action links. Links are built via raw string interpolation without URL-encoding, enabling parameter injection and redirecting admins to unintended actions.
Risk Assessment
An admin could be tricked into performing destructive actions (e.g., deletion) or accessing unauthorized resources, potentially leading to data integrity compromise.
Recommendation
Update ash_admin to version 1.3.1 or later, which includes the fix using URI.encode_query/1 for safe link construction.
Other vulnerabilities in ash_admin
See all- CVE-2026-82722High
A vulnerability in ash_admin allows any client that can reach the admin LiveView to exhaust the BEAM atom table and crash the entire node. Two LiveView event handlers intern atoms from unvalidated client input, and atoms are never garbage collected, leading to a crash.
- CVE-2026-82673High
A Path Traversal vulnerability in ash_admin allows writing attacker-controlled bytes to arbitrary paths on the server. The browser-supplied filename is not sanitized, allowing writes outside the temporary directory.
- CVE-2026-81853Low
A vulnerability in ash_admin allows authorization bypass through user-controlled keys, turning a record-lookup URL into an equality oracle over sensitive attributes. The primary key decoding does not verify that returned fields are actual primary key fields, enabling brute-force of sensitive values.
- CVE-2026-81852Low
A vulnerability in ash_admin involves the use of a hardcoded, publicly known CSP nonce, defeating nonce-based Content-Security-Policy protection. The default nonce is a constant known from the repository and is not rotated, allowing its reuse to run unauthorized scripts.
- CVE-2026-77850High
A Stored Cross-site Scripting vulnerability in ash_admin executes attacker-supplied record content as script in an administrator's browser. The RelationshipField and ManagedRelationshipSelectField components render labels without proper escaping.
- CVE-2026-75757High
A vulnerability in ash_admin relying on cookies without validation and integrity checking allows an attacker controlling a sibling subdomain to rebind an admin's session to a different actor, tenant, or authorization mode. Cookies are matched using an unanchored regular expression.
Original NVD description (English source)
Improper Encoding or Escaping of Output vulnerability in ash-project ash_admin lets an attacker who controls a record's string primary key rewrite the target of AshAdmin's row-action links. The Table, DataTable, and Show components built row-action URLs by raw string interpolation, splicing the primary key (and table, domain, and resource names) into the query string without URL-encoding. Ash resources routinely use user-settable string primary keys (slugs, emails). Because Plug.Conn.Query resolves duplicate parameters last-wins and primary_key is interpolated last, a stored key such as foo&action_type=destroy injects parameters that override the link, so an admin clicking edit is sent to a destroy form or an arbitrary resource; a # truncates the query into a fragment. The fix builds every link with URI.encode_query/1, encoding all interpolated values. This issue affects ash_admin: from 0.3.0-rc.0 before 1.3.1.
