CVE-2026-27593: Statamic CMS Auth Bypass Vulnerability

CVE-2026-27593 Overview

CVE-2026-27593 is a password reset token capture vulnerability affecting Statamic, a Laravel and Git powered content management system (CMS). Prior to versions 6.3.3 and 5.73.10, an attacker could leverage a flaw in the password reset feature to capture a user's token and reset the password on their behalf.

The attack requires the attacker to know the email address of a valid account on the target Statamic site. Additionally, the victim must click the malicious link in their email, even though they did not request the password reset. This social engineering component makes successful exploitation dependent on user interaction.

Critical Impact

Successful exploitation allows attackers to take over user accounts by intercepting password reset tokens, potentially leading to complete account compromise and unauthorized access to the CMS.

Affected Products

• Statamic CMS versions prior to 6.3.3
• Statamic CMS versions prior to 5.73.10
• All Statamic installations using the vulnerable password reset feature

Technical Details for CVE-2026-27593

Vulnerability Analysis

This vulnerability is classified as CWE-640: Weak Password Recovery Mechanism for Forgotten Password. The flaw exists in how Statamic handles password reset URL validation. Prior to the security patches, the password reset mechanism did not properly validate the reset URL, allowing an attacker to craft malicious password reset links that could expose the user's reset token.

The vulnerability requires network access and user interaction to exploit. An attacker must convince a legitimate user to click on a manipulated password reset link, which would then allow the attacker to capture the reset token and subsequently reset the victim's password.

Root Cause

The root cause of this vulnerability lies in the ForgotPasswordController.php file, which lacked proper validation of password reset URLs. The fix introduced proper URL validation using the ValidationException class along with Site and Str facades to ensure reset URLs are properly validated before processing.

Attack Vector

The attack vector is network-based and requires the following conditions:

1. The attacker must know the email address of a valid user account on the Statamic site
2. The attacker initiates a password reset request or crafts a malicious reset URL
3. The legitimate user must click on the link in their email without having requested a password reset
4. The attacker captures the reset token from the manipulated URL
5. The attacker uses the captured token to reset the victim's password

The security patches add proper validation to the password reset flow, as shown in the commit changes:

use Illuminate\Support\Facades\Password;
use Statamic\Auth\Passwords\PasswordReset;
use Statamic\Auth\SendsPasswordResetEmails;
+use Statamic\Exceptions\ValidationException;
+use Statamic\Facades\Site;

use Statamic\Http\Middleware\RedirectIfAuthenticated;
+use Statamic\Support\Str;

Detection Methods for CVE-2026-27593

Indicators of Compromise

• Unusual password reset requests for accounts where users did not initiate the reset
• Multiple password reset attempts targeting the same user account in a short timeframe
• Password reset completions immediately followed by suspicious login activity
• User reports of receiving unexpected password reset emails

Detection Strategies

• Monitor authentication logs for password reset events followed by immediate password changes from different IP addresses
• Implement alerting on password reset requests from IP addresses that differ from the user's typical login locations
• Track failed login attempts that occur shortly after password reset completions
• Review web server logs for unusual patterns in password reset URL access

Monitoring Recommendations

• Enable detailed logging for all password reset operations in your Statamic installation
• Configure alerts for multiple password reset requests targeting the same email address
• Monitor for accounts where password resets occur without subsequent legitimate user activity
• Implement anomaly detection for authentication patterns following password changes

How to Mitigate CVE-2026-27593

Immediate Actions Required

• Upgrade Statamic CMS to version 6.3.3 or later for the 6.x branch
• Upgrade Statamic CMS to version 5.73.10 or later for the 5.x branch
• Review recent password reset activity for any suspicious patterns
• Notify users to be cautious of unexpected password reset emails and to report any they receive

Patch Information

The vulnerability has been addressed in the following releases:

• Statamic 6.3.3: GitHub Release v6.3.3
• Statamic 5.73.10: GitHub Release v5.73.10

The fix implements proper validation of password reset URLs in the ForgotPasswordController.php file. For detailed technical information, refer to the GitHub Security Advisory GHSA-jxq9-79vj-rgvw.

Workarounds

• If immediate patching is not possible, consider temporarily disabling the password reset functionality until the update can be applied
• Implement additional email verification steps for password reset requests
• Educate users to never click password reset links they did not request
• Consider implementing rate limiting on password reset endpoints to slow potential attacks

# Update Statamic via Composer to the patched version
composer update statamic/cms --with-dependencies

# Verify the installed version
composer show statamic/cms | grep version
