CVE-2026-122140
Description
A flaw was found in trawl. This issue allows an unauthenticated remote attacker to bypass outbound URL security controls by supplying IPv4-mapped IPv6 addresses directly or through redirects. Successful exploitation of this Server-Side Request Forgery (SSRF) vulnerability allows an attacker to query restricted internal network endpoints, such as cloud metadata services and local loopback addresses, resulting in unauthorized information disclosure.
Statement
Moderate severity is assigned to this flaw because while an unauthenticated attacker can circumvent outbound request filters to query internal endpoints, the exploit only grants read access to network responses without enabling remote code execution or data tampering. Furthermore, the trawl package is not included or deployed in supported Red Hat products, significantly reducing direct exposure across enterprise environments.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Integrity
Technical Impact: Execute Unauthorized Code or Commands
Access Control
Technical Impact: Bypass Protection Mechanism
By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
