Security readout for executives and security teams
Plain-English summary
A WordPress plugin called Auto Login After Registration (version 1.0.0 and earlier) has a reflected cross-site scripting flaw. An attacker can craft a malicious link that, when clicked by a logged-in user, runs attacker-controlled code in that user's browser. This can lead to account hijack, data theft, or admin takeover on the affected site.
Executive priority
Schedule remediation in the next maintenance window. Risk is elevated because exploitation only requires luring a logged-in admin or user to a crafted link, but no active exploitation is reported.
Technical view
CVE-2025-49946 is a Reflected XSS (CWE-79) in the Cynob IT Consultancy Auto Login After Registration WordPress plugin through version 1.0.0. The plugin fails to neutralize untrusted input before reflecting it in a generated page. CVSS 3.1 score is 7.1 with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L; the Scope:Changed component is what elevates the score above a typical reflected XSS.
Likely exposure
Any WordPress site running Auto Login After Registration plugin version 1.0.0 or earlier with the plugin enabled and reachable on the public internet. Exposure is highest where administrators or privileged users may be phished into clicking attacker-crafted links.
Exploitation context
Patchstack classifies this as Reflected XSS, which typically requires the attacker to entice a victim (often an admin) into clicking a crafted URL. CVSS UI:R confirms user interaction is required. No KEV listing and no public exploitation campaigns are cited in the bundle.
Researcher notes
CVSS 7.1 with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L and Scope:Changed indicates the injected script can affect resources beyond the vulnerable component, which raises severity for an admin-targeted phishing scenario. CWE-79 confirms missing output encoding. Affected versions list "0" through 1.0.0; no patched version is named in the bundle, so vendor guidance must be checked directly. Confidence is medium because the source bundle relies on a single Patchstack vdb-entry without a public PoC or vendor advisory link.
Mitigation direction
- Inventory WordPress sites for the Auto Login After Registration plugin and record installed versions.
- Check the vendor and Patchstack listing for a fixed release; if none is available, disable or remove the plugin.
- Apply a Web Application Firewall rule to block reflected XSS payloads targeting this plugin's parameters.
- Remind administrators not to click unverified links into the WordPress admin area.
- Track the Patchstack advisory for updated remediation guidance.
Validation and detection
- List all WordPress installations and query plugin metadata for auto-login-after-registration and its version.
- Confirm whether the plugin is active; deactivated copies still warrant removal but are not exploitable in place.
- Review WAF and access logs for unusual query strings containing script tags or encoded HTML targeting plugin endpoints.
- After remediation, re-scan affected sites with a vulnerability scanner that consumes the Patchstack feed to confirm closure.
- Validate that administrators have unique credentials and MFA, since admin session theft is the primary impact path.
