CVE-2025-58179 – Astro Framework SSRF in Cloudflare Adapter — CyberDudeBivash Briefing

 


Summary of the Threat

  • Affected Product: @astrojs/cloudflare adapter for Astro (web framework)

  • Impacted Versions: >= 11.0.3, < 12.6.6

  • Issue Type: Server-Side Request Forgery (SSRF) permitting domain bypass

  • Endpoint in Question: /_image image optimization API (output: 'server', default imageService: 'compile')
    Attackers can exploit this to fetch any external URL via the origin server—regardless of image.domains or remotePatterns restrictions NVDmiggo.io.

Severity Metrics

  • CVSS v3.1 Score: 7.2 (High) — Network attack vector, low complexity, no privileges required, scope change, yet both confidentiality and integrity impacted moderately NVDOpenCVEFeedly.

  • CWE Classification: CWE-918 (Improper Restriction of Rendered URLs) NVDOpenCVE.

Technical Insights & PoC

  • The GET handler at /_image previously accepted arbitrary href parameters and performed an unguarded fetch, enabling SSRF.

  • Post-patch (v12.6.6), the adapter now enforces domain validation using functions like isRemoteAllowed against the configured whitelist miggo.io.

Risks & Consequences

  • Server Misuse as HTTP Proxy: Fetch internal services or external malicious content.

  • XSS Potential: If a crafted malicious asset is served under a trusted origin, it can bypass same-origin policies, leading to script-based attacks Daily CyberSecuritymiggo.io.

Published & Fixed Dates

  • CVE Published: September 4, 2025 via GitHub security advisory FeedlyOpenCVE.

  • Patch Available: Upgrade to @astrojs/cloudflare@12.6.6 or newer now suppresses the SSRF exploit.

CyberDudeBivash Remediation Playbook

Immediate Actions:

  1. Upgrade adapter to v12.6.6+.

  2. Confirm image.domains and image.remotePatterns whitelists are in place.

  3. If upgrading isn't immediate, disable image optimization entirely or restrict via your application/WAF layer.

Enhanced Defense Measures:

  • Use a Web Application Firewall (WAF) to intercept suspicious /_image?href= requests.

  • Monitor outbound image-optimization calls for anomalous behavior.

  • Audit third-party integrations using Astro in enterprise websites.

CyberDudeBivash Rapid Advisory — WordPress Plugin: Social-Login Authentication Bypass (Threat Summary & Emergency Playbook)

  TL;DR: A class of vulnerabilities in WordPress social-login / OAuth plugins can let attackers bypass normal authentication flows and obtain an administrative session (or create admin users) by manipulating OAuth callback parameters, reusing stale tokens, or exploiting improper validation of the identity assertions returned by providers. If you run a site that accepts social logins (Google, Facebook, Apple, GitHub, etc.), treat this as high priority : audit, patch, or temporarily disable social login until you confirm your plugin is safe. This advisory gives you immediate actions, detection steps, mitigation, and recovery guidance. Why this matters (short) Social-login plugins often accept externally-issued assertions (OAuth ID tokens, authorization codes, user info). If the plugin fails to validate provider signatures, nonce/state values, redirect URIs, or maps identities to local accounts incorrectly , attackers can craft requests that the site accepts as authenticated. ...
