Security readout for executives and security teams
Plain-English summary
CVE-2026-1570 affects the WordPress plugin Simple Bible Verse via Shortcode. A logged-in user with Contributor-level access or higher could store malicious script through the plugin’s shortcode. That script may run when others view the affected page, potentially exposing session data or enabling unauthorized actions in a user’s browser.
Executive priority
Treat as a moderate priority for affected WordPress sites, especially where many users can submit content. It is not described as unauthenticated or actively exploited, but stored XSS can affect administrators and visitors if malicious content is viewed.
Technical view
The issue is stored cross-site scripting in the plugin’s `verse` shortcode, caused by insufficient sanitization of user-supplied shortcode attributes and insufficient output escaping. The CVSS 3.1 score is 6.4. The described affected range is all versions up to and including 1.1. CWE-79 applies.
Likely exposure
Exposure is limited to WordPress sites using Simple Bible Verse via Shortcode versions up to 1.1 where untrusted or lower-privileged authenticated users can create content using shortcodes.
Exploitation context
Sources describe authenticated Contributor-or-higher stored XSS. The bundle does not cite active exploitation, and CISA KEV status is false. Successful exploitation requires an account with content creation capability and a victim viewing the injected page.
Researcher notes
The provided record identifies the vulnerable shortcode and links to plugin source around the relevant code. The affected-version metadata appears sparse, but the description states versions up to and including 1.1. No patch version is named in the supplied sources.
Mitigation direction
- Check vendor or plugin repository guidance for an updated fixed version.
- Remove or disable the plugin if it is not required.
- Restrict Contributor-level access to trusted users only.
- Review shortcode usage in existing posts and pages.
- Apply WordPress least-privilege controls for content authors.
Validation and detection
- Inventory WordPress sites for Simple Bible Verse via Shortcode.
- Confirm installed plugin version is above the affected range, if a fix exists.
- Review posts and pages using the `verse` shortcode.
- Check whether Contributors can publish or submit shortcode-containing content.
- Monitor for suspicious script-like content in shortcode attributes.
