Security readout for executives and security teams
Plain-English summary
CVE-2022-37720 is a stored XSS issue in Orchard CMS 1.10.3. A lower-privileged author or publisher can place malicious HTML and JavaScript in a blog post. If an administrator opens that post, the attack may run in the admin’s browser and lead to account takeover or privilege escalation.
Executive priority
Treat this as urgent for affected Orchard CMS 1.10.3 sites because compromise can cross from a low-privileged content account to administrator control. Prioritize externally reachable or multi-user publishing environments.
Technical view
The source describes CWE-79 stored cross-site scripting in Orchardproject Orchard CMS 1.10.3 blog post handling. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H, reflecting network reachability, low attack complexity, required low privileges, required victim interaction, changed scope, and high impact.
Likely exposure
Exposure is most likely on Orchard CMS 1.10.3 sites where authors or publishers can create blog posts with HTML or script-like content, especially when administrators review or load those posts while authenticated.
Exploitation context
The bundle does not show CISA KEV listing or confirmed active exploitation. The described attack requires a low-privileged account and a victim, such as an administrator, loading the malicious blog post in a browser.
Researcher notes
The CVE record provides strong severity detail but limited structured affected-product data, listing affected fields as n/a while the title and description name Orchard CMS 1.10.3. No patch details are included in the provided bundle.
Mitigation direction
- Identify any Orchard CMS 1.10.3 deployments and prioritize review.
- Check Orchard project or vendor guidance for patched versions or official mitigations.
- Restrict blog post HTML/script capabilities for low-privileged users.
- Limit author and publisher accounts to trusted users only.
- Review existing blog posts from low-privileged accounts for suspicious embedded content.
Validation and detection
- Confirm whether Orchard CMS 1.10.3 exists in the environment.
- Review roles allowed to create, edit, or publish blog posts.
- Verify content sanitization prevents script execution in rendered posts.
- Check logs for suspicious blog edits before administrator access.
- Confirm remediation against official vendor or project guidance.

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.
