CVE-2026-101925 · Severity: medium · CVSS 6.4 · Published 2026-10-01

The BBP Style Pack plugin for WordPress allows authenticated users to inject malicious scripts that persist on the site and execute when other users view affected pages. An attacker with subscriber-level access can craft a reply in a way that bypasses WordPress's text sanitization, leading to account takeover, credential theft, or malware distribution to all site visitors.

## Technical details

A stored XSS vulnerability exists in the BBP Style Pack plugin (versions up to 6.4.8) due to insufficient input sanitization and output escaping of the display_name and bbp_reply_content parameters. An authenticated attacker with subscriber-level privileges can inject arbitrary JavaScript by wrapping their crafted reply in a <pre> block, which prevents WordPress's wpautop/wptexturize processors from neutralizing the injected payload. The payload executes whenever any user accesses the injected page.
