Security readout for executives and security teams
Plain-English summary
CVE-2026-1911 affects the WordPress Twitter Feeds plugin up to version 1.0.0. A logged-in user with Contributor-level access or higher could store malicious script through a shortcode attribute. That script may run when others view the affected page, creating risk to site users and administrators.
Executive priority
Treat as a moderate-priority web risk. It is not reported as actively exploited, but affected sites with multiple content contributors should act promptly because stored XSS can affect visitors and administrators viewing compromised pages.
Technical view
The issue is stored cross-site scripting in the 'TwitterFeeds' shortcode 'tweet_title' parameter, caused by insufficient input sanitization and output escaping. Wordfence rates it CVSS 6.4, vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N. CWE-79 applies. Public references point to plugin code around line 490.
Likely exposure
Exposure is limited to WordPress sites using Twitter Feeds versions up to and including 1.0.0, especially where untrusted or semi-trusted users have Contributor or higher roles. Sites without this plugin or without such users are less likely exposed.
Exploitation context
The source bundle does not show CISA KEV listing or public active exploitation. Exploitation requires authenticated WordPress access with Contributor-level privileges or above, but does not require victim interaction beyond viewing an injected page.
Researcher notes
The CVE record and Wordfence identify stored XSS via the tweet_title shortcode attribute. Public references include trunk and 1.0.0 code locations, but the provided sources do not name a specific patched version. Avoid assuming remediation beyond vendor guidance or plugin removal.
Mitigation direction
- Check vendor and Wordfence guidance for an official fixed version or remediation.
- If no fixed version is available, consider disabling or removing the plugin.
- Restrict Contributor and higher roles to trusted users only.
- Review posts and pages using the TwitterFeeds shortcode.
- Apply normal WordPress hardening, including least privilege and plugin inventory control.
Validation and detection
- Inventory WordPress sites for the Twitter Feeds plugin.
- Confirm installed plugin version is greater than 1.0.0, if a fixed release exists.
- Review content for TwitterFeeds shortcodes using the tweet_title attribute.
- Check WordPress users with Contributor, Author, Editor, or Administrator roles.
- Monitor web and WordPress logs for suspicious content edits.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
