Security readout for executives and security teams
Plain-English summary
CVE-2018-19350 is a stored cross-site scripting issue in SeaCMS v6.6.4. A malicious value saved through the password-change email field could later run script-like content in another user's browser. The sources do not provide a CVSS score, named patch, or evidence of active exploitation.
Executive priority
Address if SeaCMS v6.6.4 is exposed to untrusted users, especially on public sites. Business urgency is moderate because stored XSS can support account abuse, session theft, or admin-targeted attacks, but available sources do not confirm active exploitation or broad product impact.
Technical view
SeaCMS v6.6.4 stores unsafe content submitted through member.php?action=chgpwdsubmit in the email parameter during password change. The CVE record describes stored XSS demonstrated using a data URL inside an OBJECT element. Affected CPEs, vulnerable version range, CWE, and CVSS metrics are not provided in the bundle.
Likely exposure
Exposure appears limited to SeaCMS v6.6.4 deployments with the member password-change email update path enabled. The source bundle does not confirm other affected versions, CPEs, hosted services, or downstream forks.
Exploitation context
A public GitHub reference is listed for the issue, but the bundle does not show CISA KEV listing or other cited evidence of active exploitation. Treat it as publicly disclosed, not confirmed exploited in the wild.
Researcher notes
Evidence is sparse: the CVE record names SeaCMS v6.6.4, one parameter, one endpoint, and a public reference. No CVSS, CWE, CPE, affected range, patch version, or exploitation telemetry is included. Avoid expanding scope beyond the cited version without independent vendor evidence.
Mitigation direction
- Check SeaCMS or maintainer guidance for a fixed release or official advisory.
- Inventory and prioritize any internet-facing SeaCMS v6.6.4 instances.
- Restrict access to member account-management functions where feasible.
- Validate email fields strictly and encode stored values before rendering.
- Review stored user profile data for unexpected markup or data URLs.
Validation and detection
- Confirm whether any production asset runs SeaCMS v6.6.4.
- Review member.php password-change handling for email storage and rendering paths.
- Check whether email values are validated as email addresses only.
- Inspect logs and stored profiles for suspicious markup in email fields.
- Verify any vendor update or local fix in a staging environment first.
