Dns-Rebinding

A DNS rebinding vulnerability in the NLTK pathsec module allows attackers to bypass SSRF filters and access restricted internal resources by manipulating hostname resolution during the validation and connection phases.

The `datamodel-code-generator` tool is vulnerable to a Server-Side Request Forgery (SSRF) protection bypass, identified as CVE-2026-55391, due to a time-of-check/time-of-use (TOCTOU) race condition through DNS rebinding, allowing attackers to access internal services like cloud instance metadata endpoints when processing attacker-influenced URLs.

A race condition exists in OpenClaw versions before 2026.5.28 within the MS Teams safeFetch DNS rebinding check, allowing a lower-trust caller to exploit a timing window between the DNS validation check and its use, potentially bypassing authorization or policy checks if the affected feature is enabled and reachable.

PraisonAI versions prior to 1.6.78 are vulnerable to server-side request forgery (SSRF) within its web_crawl tool, allowing attackers to bypass hostname validation using DNS rebinding and retrieve sensitive internal HTTP response bodies from private or loopback services.

PraisonAI versions prior to 1.6.78 are vulnerable to server-side request forgery (SSRF) due to an issue in the Crawl4AI/Chromium backend, allowing attackers to bypass existing SSRF validation by employing DNS rebinding and HTTP redirects to access and exfiltrate sensitive internal responses, including canary values.

An unspecified attacker can achieve remote code execution in Serena agent versions prior to 1.5.2 by leveraging an unauthenticated Flask dashboard, DNS rebinding, and memory poisoning, enabling persistent attacker-controlled command execution.

The `rmcp` crate before v1.4.0 is vulnerable to DNS rebinding attacks via the Streamable HTTP server transport due to missing Host header validation, potentially allowing arbitrary code execution on a victim's machine if they visit a malicious website.

A DNS rebinding vulnerability exists in java-sdk versions prior to 1.0.0, allowing an attacker to access a locally or network-private java-sdk MCP server via a victim's browser, potentially enabling unauthorized tool calls to the server.
