Security readout for executives and security teams
Plain-English summary
CVE-2026-1573 affects the OMIGO WordPress plugin through version 3.3. A logged-in user with Contributor-level access or higher could place malicious script content into pages using the donation button shortcode. The script can run when someone views the affected page, potentially exposing session data or changing page behavior.
Executive priority
Treat as a moderate-priority website risk. It is not known to be actively exploited, but it can let a low-privileged account affect visitors or administrators. Prioritize sites with many contributors, public registration, or sensitive admin workflows.
Technical view
The issue is stored cross-site scripting in the `omigo_donate_button` shortcode. Sources attribute it to insufficient sanitization and output escaping of user-supplied shortcode attributes. It requires authenticated low-privilege access, is network exploitable, and has CVSS 3.1 score 6.4 with scope changed and low confidentiality/integrity impact.
Likely exposure
WordPress sites using the OMIGO plugin at versions up to and including 3.3 are potentially exposed, especially if untrusted users can create or edit posts. Sites without the plugin, without Contributor-level users, or without affected shortcode usage have lower practical exposure.
Exploitation context
No provided source indicates active exploitation, and it is not listed as KEV. Exploitation requires an authenticated Contributor-or-higher account and a page or post path where the shortcode can be saved and viewed by others.
Researcher notes
Evidence comes from the CVE description, Wordfence advisory, and WordPress plugin source reference. The bundle does not name a fixed version or vendor mitigation. Avoid assuming exploit availability; focus validation on plugin presence, version, role model, and shortcode usage.
Mitigation direction
- Check vendor or WordPress plugin guidance for a fixed OMIGO release.
- Update OMIGO if a patched version is available from trusted sources.
- Restrict Contributor and higher roles to trusted users only.
- Review pages and posts using the OMIGO donation shortcode.
- Remove suspicious shortcode attributes or unexpected script-like content.
Validation and detection
- Inventory WordPress sites for the OMIGO plugin.
- Confirm installed OMIGO versions, prioritizing versions 3.3 and earlier.
- Identify posts or pages containing the `omigo_donate_button` shortcode.
- Review recent Contributor-level content changes for suspicious embedded attributes.
- Monitor WordPress security feeds for vendor remediation updates.
