api.rexflash.app security report

External security assessment · 10 issues detected.

ScanLabsAI ran a standard security scan of api.rexflash.app, checking its SSL/TLS configuration, HTTP security headers, DNS records. The results below reflect what is detectable from outside the site and earned it an overall grade of C. api.rexflash.app has several security gaps. None may be critical alone, but together they widen the attack surface and should be addressed.

Issues detected

Missing Content Security Policy

A Content-Security-Policy header helps block cross-site scripting (XSS) and data-injection attacks by controlling which sources a browser may load. Without it, injected scripts are far easier to exploit.
Missing HTTP Strict Transport Security

HTTP Strict Transport Security (HSTS) forces browsers to use HTTPS, preventing protocol-downgrade and man-in-the-middle attacks against users who type the bare domain.
Missing X-Frame-Options

Without X-Frame-Options (or a CSP frame-ancestors rule) the site can be embedded in a hidden iframe and used for clickjacking attacks.
Server Software Disclosure

This issue was detected during an external security scan and can weaken the site’s resistance to common web attacks. Run a full scan to see its severity, evidence and remediation steps.
Missing X-Content-Type-Options

X-Content-Type-Options: nosniff stops browsers from MIME-sniffing responses, which can otherwise turn a harmless file into an executable script.
Missing Referrer-Policy

A Referrer-Policy header controls how much URL information leaks to third-party sites, protecting user privacy and internal paths.
Missing Permissions-Policy

A Permissions-Policy header restricts which powerful browser features (camera, microphone, geolocation) pages and embedded content may use.
Missing Cross-Origin-Opener-Policy

Cross-Origin-Opener-Policy isolates the browsing context, mitigating cross-window attacks and side-channel leaks such as Spectre.
Missing Cross-Origin-Resource-Policy

Cross-Origin-Resource-Policy limits which origins can load your resources, reducing the risk of cross-origin data leaks.
Missing Cross-Origin-Embedder-Policy

Cross-Origin-Embedder-Policy ensures resources are explicitly allowed to be embedded — a prerequisite for strong cross-origin isolation.

Frequently asked questions

Is api.rexflash.app safe?

Based on an external ScanLabsAI security scan, api.rexflash.app scored C (63/100). api.rexflash.app has several security gaps. None may be critical alone, but together they widen the attack surface and should be addressed. An external scan measures publicly detectable security posture, not internal controls.

What does a C security grade mean?

The C grade reflects the SSL/TLS, security-header, DNS and known-vulnerability checks ScanLabsAI observed from outside api.rexflash.app. api.rexflash.app has several security gaps. None may be critical alone, but together they widen the attack surface and should be addressed.

How is the api.rexflash.app security score calculated?

ScanLabsAI weights findings by severity: critical and high-severity issues reduce the score the most, while common medium and low issues (such as missing security headers) have a smaller impact. The result is a 0–100 score mapped to a letter grade from A+ to F.

How can api.rexflash.app improve its security score?

Address the 10 detected issues — starting with the highest severity — then re-scan to confirm. Common quick wins include adding missing security headers and enforcing HTTPS with HSTS.

How this report is produced

ScanLabsAI is an AI-powered website security scanner. This report is generated by a passive external scan — it reads publicly available information the way a visitor would and never attempts to exploit, alter or damage the site. Findings are weighted by severity to produce the 0–100 score and A+–F grade shown above. A grade reflects externally detectable posture and is not a guarantee of overall security.

ScanLabsAI runs a multi-engine security scan (SSL/TLS, security headers, DNS, and known-vulnerability checks) and grades a website's public security posture. Grades reflect issues detectable from the outside and are not a guarantee of overall security.
