Stored XSS via unsanitized article titles

Published Mar 24, 2026 · Updated Mar 24, 2026

Stored XSS in bolo-blog Bolo-Solo 2.6.0 through 2.6.4 allows remote authenticated users to execute script in article visitors’ browsers. The article-creation endpoint stores the articleTitle value without sanitization, and the rendered title executes attacker-supplied HTML and script. Access to the administrative article editor is required to plant a payload; every visitor who opens the published article triggers it.
