CVE-2026-10038: CWE-639 Authorization Bypass Through User-Controlled Key in smub Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More
The Charitable – Donation Plugin for WordPress (up to version 1.8.11.1) contains an authorization bypass vulnerability that allows authenticated users with Subscriber-level access or higher to delete arbitrary media attachments. This occurs because the plugin does not validate ownership of attachment IDs when updating user avatars, enabling attackers to poison the avatar meta with attacker-chosen attachment IDs and trigger deletion.
AI Analysis
Technical Summary
CVE-2026-10038 is an authorization bypass vulnerability in the Charitable – Donation Plugin for WordPress (up to 1.8.11.1). The vulnerability arises from the save_avatar() function calling wp_delete_attachment() on an attachment ID sourced from the user's 'avatar' meta without verifying ownership. The Charitable_Data_Processor::process_picture() method returns the raw posted value when no file is uploaded, allowing attackers to set the 'avatar' meta to arbitrary attachment IDs. Consequently, authenticated users with Subscriber-level privileges can delete arbitrary attachments from the Media Library by first poisoning the avatar meta and then triggering the deletion via a normal avatar upload.
Potential Impact
An attacker with authenticated access at Subscriber level or above can delete arbitrary media attachments from the WordPress Media Library. This leads to integrity loss of media content but does not affect confidentiality or availability of the system. The CVSS score is 4.3 (medium severity), reflecting the limited scope and required privileges.
Mitigation Recommendations
No official patch or remediation is currently confirmed. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict user roles and permissions carefully and monitor for suspicious activity related to avatar updates. Avoid granting unnecessary upload or media management capabilities to low-privilege users.
