CVE-2026-8872
The Animate Your Content plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'animation-set' shortcode in versions up to, and including, 1.0.0. This is due to insufficient input sanitization and output escaping on user supplied attributes in the shortcode_args_to_html_attrs() function, which concatenates shortcode attribute values directly into double-quoted HTML attributes without calling esc_attr(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
- Base score: 6.4
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.19%
- Percentile among all scored CVEs: 8
- Score date: 10/5/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
