CVE-2026-107774 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It affects Dokan: AI Powered WooCommerce Multivendor Marketplace Solution; fixed in 5.3.3.

## Summary

The Dokan multivendor marketplace plugin for WordPress and WooCommerce lets an attacker use the store contact form to make the site send emails to its vendors that appear to come from an address on the site's own domain, such as its administrator. Because these emails align with the domain's SPF and DKIM records, they can pass email authentication checks.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unknown Dokan: AI Powered WooCommerce Multivendor Marketplace Solution: fixed in 5.3.3

## Description

The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution WordPress plugin before 5.3.3 does not use a trusted site-owned sender address when relaying its store contact form, instead placing the unauthenticated submitter's supplied address directly in the message's From header rather than a Reply-To, allowing unauthenticated attackers to make the site email its own vendors with the sender spoofed to an address at the site's own domain (such as its administrator), aligned with the domain's own SPF/DKIM.
