What is CVE-2026-129155?

DjangoBlog versions 2.0.0.0 through 2.1.0.0 are vulnerable to a stored cross-site scripting flaw due to improper handling of event-handler attributes in the comment sanitizer class_filter. This vulnerability allows authenticated users to submit comments containing malicious script via div elements with autofocus and onfocus attributes, which executes automatically whenever the page is accessed. This puts all visitors at risk, including administrators, by compromising the integrity of the site.

Affected Version(s)

DjangoBlog 2.0.0.0 <= 2.1.0.0
