CVE-2025-39385 Overview
CVE-2025-39385 is a missing authorization vulnerability in the vowelweb Sirat WordPress theme. The flaw stems from incorrectly configured access control security levels [CWE-862]. It affects all versions of Sirat up to and including 1.5.1. Authenticated attackers with low privileges can abuse the missing authorization check over the network to affect integrity. The vulnerability requires no user interaction and can be triggered remotely against any WordPress site running an affected version of the theme.
Critical Impact
Authenticated low-privilege users can perform actions restricted to higher-privileged roles, resulting in unauthorized modifications within WordPress sites running the Sirat theme.
Affected Products
- vowelweb Sirat WordPress theme versions up to and including 1.5.1
- WordPress installations that have the Sirat theme active
- Multisite deployments where the vulnerable theme is network-enabled

Technical Details for CVE-2025-39385
Vulnerability Analysis
The Sirat theme exposes functionality without verifying that the requesting user has the required capability. WordPress relies on developers to invoke current_user_can() or nonce checks before privileged actions execute. The Sirat theme omits or misconfigures these checks on one or more handlers, allowing subscriber-level accounts to reach code paths intended for administrators or editors. The result is a broken access control condition that impacts data integrity within the theme's scope.
Because many WordPress deployments allow open user registration, an attacker can register a low-privilege account and immediately exercise the vulnerable endpoint. The confidentiality and availability of the site are not directly impacted by this issue, but integrity changes can enable follow-on attacks such as content manipulation or configuration tampering.
Root Cause
The root cause is a missing authorization check [CWE-862] in the Sirat theme's request handlers. The affected code paths trust the authenticated session without validating role or capability. See the Patchstack Vulnerability Report for the technical breakdown.
Attack Vector
Exploitation occurs over the network against the WordPress admin-ajax.php or a theme-registered REST route. The attacker authenticates as any registered user, then issues a crafted HTTP request to the vulnerable handler. No user interaction and no elevated privileges are required beyond a standard subscriber account.
No public proof-of-concept code is available. Refer to the Patchstack Vulnerability Report for advisory-level details.

Stop Identity AttacksDetection Methods for CVE-2025-39385
Indicators of Compromise
- Unexpected POST requests to /wp-admin/admin-ajax.php from accounts holding the subscriber role
- Modifications to theme options, posts, or settings by users without editor or administrator capabilities
- Newly registered accounts immediately issuing requests to Sirat theme handlers
Detection Strategies
- Audit WordPress access logs for repeated requests to theme-specific AJAX actions or REST endpoints prefixed with the Sirat namespace
- Correlate WordPress user role data with action logs to identify privilege mismatches on write operations
- Deploy a Web Application Firewall (WAF) rule that flags authenticated low-privilege requests targeting Sirat action names
Monitoring Recommendations
- Enable WordPress activity logging plugins that record user role, action, and target object for every administrative event
- Forward WordPress and web server logs to a centralized SIEM for correlation across authentication and application layers
- Alert on creation of new subscriber accounts followed by write operations to theme configuration
How to Mitigate CVE-2025-39385
Immediate Actions Required
- Inventory all WordPress sites and identify installations running the Sirat theme at version 1.5.1 or earlier
- Disable the Sirat theme on affected sites until a patched release is deployed
- Restrict new user registration or require administrator approval on public-facing WordPress sites
- Rotate credentials for any accounts that may have exercised the vulnerable endpoint
Patch Information
At the time of publication, the Patchstack Vulnerability Report lists all versions through 1.5.1 as affected. Monitor the vendor and Patchstack advisory for a fixed release and upgrade immediately once available.
Workarounds
- Switch to an alternative WordPress theme until the vendor issues a fix
- Deploy WAF rules that block unauthenticated and low-privileged access to Sirat theme AJAX actions and REST routes
- Enforce least-privilege role assignments and remove unused subscriber accounts
