• Severity: medium (CVSS 5.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-06-12 · updated 2026-06-17
• Weakness: CWE-79

Description

The BuddyPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘display_name’ parameter in versions up to, and including, 12.4.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• BuddyPress: before 12.5.1 — fixed in 12.5.1

How to fix

Upgrade to a fixed version: BuddyPress 12.5.1. Check the vendor advisory for mitigations.
