- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- smub Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More: through 1.8.11.1

## Description

The Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More plugin for WordPress is vulnerable to Insecure Direct Object Reference / Authorization Bypass leading to Arbitrary Attachment Deletion in versions up to, and including, 1.8.11.1 via the profile avatar update flow. This is due to the save_avatar() function in Charitable_Profile_Form calling wp_delete_attachment() on an attachment ID read from the user's 'avatar' meta without validating that the attachment is owned by the user, combined with Charitable_Data_Processor::process_picture() returning the raw posted value when no file is uploaded, allowing the 'avatar' user meta to be poisoned with any attacker-chosen attachment ID. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary attachments from the Media Library by performing a two-request chain (first poisoning the stored avatar meta value with a target attachment ID, then triggering deletion via a normal avatar upload).
