Grav v1.7.49.5 / Admin v1.10.49.1 – User Enumeration & Email Disclosure Summary A user enumeration and email disclosure vulnerability exists in Grav v1.7.49.5 with Admin plugin v1.10.49.1. The "Forgot Password" functionality at /admin/forgot leaks information about valid usernames and their associated email addresses through distinct server responses. This allows an attacker to enumerate users and disclose sensitive email addresses, which can be leveraged for targeted attacks such as password spraying, phishing, or social engineering. Details The issue resides in the taskForgot() function, which handles the forgot password workflow. Relevant vulnerable logic: When an attacker submits the password reset form at /admin/forgot with an invalid username, the application responds with: However, when a valid username is supplied, and the attacker repeatedly triggers password reset requests, the application responds with: This discrepancy in responses enables: 1.

# Patch Next advisory brief: CVE-2025-66307

Advisory: Grav Admin Plugin vulnerable to User Enumeration & Email Disclosure
IDs: CVE-2025-66307, GHSA-q3qx-cp62-f6m7
Record: https://patchnext.com/advisories/cve-2025-66307 (revision 1, source checked 26 Oct 2026, 14:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: getgrav/grav 1.8.0-beta.27. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist getgrav/grav: affected < 1.8.0-beta.27; fixed in 1.8.0-beta.27

## Suggested inspection (read-only)
- Packagist getgrav/grav: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on getgrav/grav.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-q3qx-cp62-f6m7 (GitHub-reviewed advisory GHSA-q3qx-cp62-f6m7 lists affected ranges: Packagist getgrav/grav >=0 <1.8.0-beta.27)
